                                  PART I

ITEM I.  BUSINESS

Tellabs, Inc., an Illinois corporation, began operations in 1975 and became
publicly owned in 1980.  During 1992, the Illinois corporation merged with
and into Tellabs Operations, Inc., a wholly owned subsidiary.  As a result
of the merger, Tellabs Operations, Inc., became a subsidiary of Tellabs,
Inc., a Delaware corporation (with its subsidiaries, unless the context
indicates otherwise, "Tellabs" or the "Company").  The Company designs,
manufactures, markets and services voice and data transport and network
access systems that are used worldwide by public telephone companies,
long-distance carriers, alternate service providers, cellular and other
wireless service providers, cable operators, government agencies,
utilities, and business end-users.

Products provided by the Company include digital cross-connect systems,
managed digital networks, network access and wireless system products.
Digital cross-connect systems include the Company's TITAN (a registered
trademark of Tellabs Operations, Inc.) 5500 and 5300 series of digital
cross-connect systems.  Managed digital networks include the Company's
Martis (a registered Finnish trademark of Tellabs Oy) DXX (a registered
Finnish trademark of Tellabs Oy) integrated access and transport system
(the Martis DXX system), statistical multiplexers, packet switches, and T1
multiplexers, and network management systems.  Network access products
include digital signal processing (DSP) products such as echo cancellers
and T-coders; special service products (SSP) such as voice frequency
products; and local access products such as the CABLESPAN (a registered
trademark of Tellabs Operations, Inc.) system.  The Company, through the
acquisition of the outstanding shares of the Steinbrecher Corporation
(presently known as the Tellabs Wireless Systems Division), acquired
technology that will form the basis of a new wireless local loop product
which is expected to be introduced during 1997 as well as the existing
DataCell (a trademark of Tellabs Operations, Inc.) Mobile Data Base Station
product.

The Company's products are sold in both the domestic and international
marketplaces (under the Tellabs name and trademarks and under private
labels) through the Company's field sales force and selected distributors
to a major customer base.  This base includes Regional Bell Operating
Companies (RBOCs), independent telephone companies (ITCs), interexchange
carriers (IXCs), local telephone administrations (PTTs), local exchange
carriers (LECs), original equipment manufacturers (OEMs), cellular and
other wireless service companies, cable operators, alternate service
providers, system integrators, government agencies, and business end-users
ranging from small businesses to Fortune 500 companies.

The availability of digital technology along with the use of
microprocessors and other custom and standard very large-scale integrated
(VLSI) circuitry continues to make it economically possible for the Company
to expand its product lines to meet the changing customer demands and
industry trends inherent in today's dynamic telecommunications environment.
This expansion primarily involves the development of broad lines of
service-provider-oriented networking systems that meet the ever increasing

                                   2 

demands for efficient, multipurpose data, video, and voice communications
services. 

This same availability of technology in capital equipment makes it possible
for the Company to efficiently and competitively continue to produce its
own products in its world class manufacturing facilities located throughout
the world. 

Each of the Company's manufacturing operations is registered under the ISO
9000 standard.  ISO 9000 is an international set of standards developed to
provide quality assurance for companies seeking to improve their quality
standards and customer service. 

Digital Cross-Connect Systems 

The TITAN product family consists of software intensive digital
cross-connect systems and network management platforms.  These flagship
products address the needs of RBOCs, PTTs, IXCs, alternate local exchange,
cellular, cable, government and Fortune 500 companies.  These complex
transmission systems are designed to meet or exceed domestic and
international telephone industry standards. 

The SONET (synchronous optical network) digital cross-connect systems
operate under software control and are typically used to build and control
the wideband and broadband transmission infrastructure of telecommunication
service providers.  Telecommunication managers utilize the digital
cross-connect systems to reduce cycle time while minimizing capital and
operating expense.  Key applications include centralized and remote testing
of transmission facilities, grooming of voice, data, and video signals,
automated provisioning of new services, and restoration of failed
facilities.  All of the TITAN systems include a feature for monitoring
facility performance which enhances "process of elimination
troubleshooting" in a complex network.  The user can determine the early
warnings of facility degradation rather than reacting to a network outage.
The digital cross-connect system also converts international to domestic
transmission and signaling standards.  These products augment the ability
of users to provide current, emerging, and future service to business and
residential customers.  Advanced survivable business services also utilize
the TITAN products for interconnecting fiber transmission. 

The TITAN systems vary in switching rate and facility interface speed.
Tellabs offers the SONET TITAN 5300 series of cross-connect systems that
can interface facilities at STS-1, DS3, DS1, E1, DS0, and subrate levels,
and can switch them at DS0 levels and below.  The systems in this series
allow modular non-service affecting growth with capacities ranging from 8
to 4,000 ports. 

Tellabs also offers the Company's flagship SONET TITAN 5500 system which
interfaces facilities at the DS1, DS3, STS-1 and/or fiber optic OC-N
levels, and cross-connects them at levels of DS1/VT1.5 and above.  The
TITAN 5500 is the first digital cross-connect system in the world to
integrate optical (N=3,12) equipment.  A single TITAN 5500 system can
carry the equivalent of 700,000 simultaneous phone conversations. 

In 1997, the Company plans to introduce the TITAN 5200 Broadband Node,
which will extend the benefits of the wideband digital cross-connect
system, such as the TITAN 5500, to small end office, point-of-presence,
outside plant, and customer premise locations.  This product, which is

                                   3 
based on technology acquired from TRANSYS Networks, Inc. in June of 1996,
will interoperate with TITAN 5500 nodes on OC-3 and OC-12 rings and provide
flexible bandwidth management for DS1, DS3, and other customer facilities.

Digital cross-connect system products accounted for approximately 57
percent, 49 percent, and 46 percent of 1996, 1995, and 1994 sales,
respectively. 

Managed Digital Networks 

Since Tellabs' entry into the data communications marketplace in 1983, the
Company has developed a comprehensive family of networking products to
address the requirements and flexibility demanded by the users of
communications services.  Products within this group include the Martis DXX
system and the CROSSNET ( a registered trademark of Tellabs Operations,
Inc.) family of network-compatible T1/E1 time division multiplexers. 

The Martis DXX system is a complete managed access and transport network
system designed to be used by telecommunications service providers
worldwide for the delivery of business services, digital leased lines and
integrated customer access.  Typical business service applications include
PABX networking, high speed data access, value added data services such as
frame relay and X.25, and voice telephony.  An additional application of
the Martis DXX system is the provision of the transport infrastructure for
mobile networks such as digital and analog cellular, paging, trunked mobile
radio and mobile data.  The Martis DXX systems are also used as general
purpose backbone networks carrying the wide variety of services that may be
provided by the public telecommunications service provider. 

Recent enhancements to the DXX system have focused on extending the
current product portfolio with new features and functions including a wider
variety of access configurations and speeds as well as significant
enhancements to the DXX network management system to provide advanced
management options to the public telecommunications service provider.  The
DXX system has also been enhanced to provide high speed optical synchronous
digital hierarchy (SDH) interfaces and to support cell and packet-based
technologies such as frame relay and ATM planned for the future. 

The CROSSNET 440, 441 and 442 products are a family of intelligent T1/E1
multiplexers that interface voice, data and video devices (up to 2.048Mbps)
and multiplex them over private time division multiplexing networks.  The
CROSSNET 445 provides timeslot interchange and DS0/DS1 switching and is
used to network 440, 441 and 442 nodes.  This family of intelligent
multiplexers can be provisioned (network-wide) from any one node.  In
addition, they can automatically provision many of the voice and data
applications and have an integrated network management system that can
adjust the bandwidth in 400bps increments for highly efficient use of the
DS1 or fractional DS1 facility.  The CROSSNET family of multiplexers
provides low bit rate voice (LBRV) compression at 8 and 16 kbps in its DS0
channels and T1 trunks, enhanced analog voice capability for competing in
the growing branch office multiplexer market and a variable-speed network
interface (NX64) to the CROSSNET 44X for use with international networks or
satellite radio channels. 

These products compete in the Wide Area Network (WAN) access market.  End-
users buy these products through value added re-sellers, service providers
and direct from the Company.  The products are used to combine voice, data
and video applications for transmission over T1, FT1, E1, NX56 and NX64

                                   4 
facilities.  They provide for more efficient utilization of the bandwidth
and access to dedicated services. 

Although the CROSSNET product line serves a maturing market that is
migrating to newer technologies such as frame relay and ATM, there
continue to be significant opportunities for the traditional CROSSNET
multiplexers in both the domestic and international markets.

Managed digital networks accounted for approximately 28 percent, 28
percent, and 27 percent, of 1996, 1995, and 1994 sales, respectively. 

Network Access Systems 

Network access products are primarily modular in design and can be used
either individually or in complex systems and assemblies.  The three areas
making up network access products are DSP products, SSP products, and local
access products.  The products are designed to meet telephone industry
standards, and, in many applications, they directly interface with customer
premises equipment.  These products enhance the ability of LECs, PTTs,
IXCs, wireless, private networks, alternate service providers and cable
providers to provide current, emerging, and future services to their
business customers through innovative products and systems that provide
more cost-effective provisioning of existing basic services.  In order to
continue to grow this product area, state-of-the-art technology will be
deployed and value-added content will be provided. 

DSP products primarily address the needs of cellular companies, LECs, and
IXCs, both domestically and internationally.  Such products include the
Company's echo cancellation (or control) and voice compression products.
The echo control products primary function is to provide voice quality
enhancements such as the removal of irritating feedback (from one's own
voice) that occurs on virtually all long distance connections and many
wireless connections.  The voice compression product (T-Coder) doubles the
capacity of digital transmission facilities used for voice and data
services.  This product has great economic appeal to cellular companies,
IXCs, and end-users who want to double T1 or E1 capacity without incurring
the cost of a new facility.  These DSP products have benefited from the
growth of the markets that these products address. 

SSP products provide transmission and signaling conversion between the
central office and the customers' terminal equipment.  These products
include: line amplifiers that compensate for loss and distortion in voice
and analog data transmission applications; terminating devices that provide
conversion between 4 wire transmission facilities and 2 wire local lines;
signaling equipment and systems that convert station on-hook/off-hook,
dialing and ringing information to signaling formats compatible with
transmission over metallic voice channels; and loop treatment equipment
typically used to extend the distance from a central office at which a
telephone functions satisfactorily.  The Company also designs, manufactures
and sells a line of voice conferencing and alerting systems and a series of
products with remote alignment and diagnostic maintenance capabilities.

The Company's CABLESPAN 2300 system is a local access product developed
between the Company and Advanced Fibre Communications, Inc. (AFC),
designed to address the emerging cable and alternate service provider
markets.  The CABLESPAN 2300 "Universal Telephony Distribution System" is a
next-generation, multiple services delivery system that allows cable
television (CATV) providers, alternate access carriers (ALTs), and

                                   5 
competitive access providers (CAPs) to build flexible communication
networks that support the integrated delivery of video, voice, data and
information services.  The product provides maximum application flexibility
through its ability to support a wide variety of network topologies,
interface with various forms of transmission media and provide the
modularity required to support both residential and business customers.
The CABLESPAN system can be managed either directly from an integral
interface that provides local and remote management or from a PC-based
stand-alone Element Management System (EMS) that allows the management of
multiple CABLESPAN systems and supports multiple network operators while
interfacing with other operational support systems. 

Network access products accounted for approximately 15 percent, 21
percent, and 26 percent of 1996, 1995, and 1994 sales, respectively. 

Wireless Systems Division 

In April 1996, the Company acquired all of the outstanding shares of
Steinbrecher Corporation.  This acquisition formed the basis of a new
division within the Company, the Tellabs Wireless Systems Division
(Wireless Systems Division). 

Steinbrecher, through over 20 years of performing subcontractor activities,
primarily in military projects, had gained unique insights in the
development of sophisticated radio frequency (RF) designs.  The new
Wireless Systems Division is engaged in the completion of a software
programmable wideband digital base station (base station) which was
initiated prior to the Company's acquisition of Steinbrecher.  This base
station product will be used in conjunction with the Company's other
products such as the TITAN digital cross-connects, Martis DXX system and
echo cancellers to expand the product portfolio offered to the wireless
marketplace as well as to allow the Company to provide more comprehensive
wireless solutions. 

The Company's intention is for the Wireless Systems Division to pursue
two markets.  The first target market is wireless local loop - a new market
for wireless technology which uses radio technology to provide residential
and small business with telephony services.  This type of sophisticated
radio is proving to be a very economical alternative to the traditional
method of installing buried copper wires to provide these same services.
The Company believes that the primary addressable markets for this wideband
wireless local loop technology will be in the Asia/Pacific and Latin
America regions. 

The second marketplace for this technology lies in providing microcell
solutions using this same wideband base station.  The market for this
technology is primarily in developed areas of the world (including the
United States) where cellular or PCS wireless networks are being built out.
The systems' small form factor and lower initial price allow it to be a
very effective tool to provide RF coverage in harder to cover areas such
as indoor and underlay applications or interleaving larger macrocells
where focused RF coverage is required.  In addition, the system can also be
used to provide targeted increased capacity for higher congestion areas
such as busy airports or downtown areas where not enough simultaneous users
can be supported within the current macrocellular approach. 

The Company expects to begin field trials of both the wireless local loop
and base station products during 1997.

                                   6 
The DataCell Mobile Data Base Station, Steinbrecher's commercially
available product acquired in the acquisition, is used by 800 MHz AMPs
cellular companies to provide wireless packet services.  The market for
this product is primarily in the United States and Latin America. 

MARKETING

Sales are generated through the Company's direct sales organization and
selected distributors.  The United States sales group consists of
approximately 77 direct sales personnel, and additional sales agents and
sales support personnel located throughout the United States.  The
International sales group consists of approximately 50 direct sales
personnel, and additional sales agents and sales support personnel in
Canada, Latin America, South America, Europe, the Middle East, Africa, Asia
and Australia. 

The United States sales organization conducts its activities from the
corporate headquarters and six regional or district offices.  The
International sales organization conducts its activities from the corporate
headquarters and twenty-five regional offices.  The regional offices are
generally staffed by a regional sales manager, system sales engineers, and
additional personnel as required. 

Direct orders through the Company's field sales organization accounted for
approximately 89 percent of 1996 sales.   

The Company has national account managers to coordinate sales activities
for its major customer groups, and product managers to coordinate the
marketing activities for each major product area.

The United States sales organization uses a vertical markets approach for
the sales of its products.  As a result, large accounts such as RBOCs,
IXCs, Wireless, Alternate Service Providers, and General Market Customers
are serviced by teams to better represent both product and service
offerings.  The International sales organization is structured to support
activities on a regional basis. 

The Company has arrangements with a number of distributors of
telecommunications equipment, both in the United States and
internationally, some of whom maintain inventories of the Company's
products to facilitate prompt delivery.  These distributors provide
information on the Company's products through their catalogs and through
trade show demonstrations.  The Company's field sales force also assists
these distributors with regular calls to them and their customers.
Distributors, as a group, accounted for approximately 11 percent of 1996
sales.  No single distributor accounted for more than 10 percent of 1996
sales. 

CUSTOMER SERVICE 

The Company maintains a worldwide customer service organization focused
on providing its customers high quality technical and administrative
product support.  To ensure global support, Tellabs has five worldwide
logistic centers (Lisle, Illinois; Shannon, Ireland; Mississauga, Canada;
Espoo, Finland; and Hong Kong). 

The Company's customer service organization supports its customers with a
wide range of services that include application engineering and support,

                                   7 
installation, service agreements, on-site training, product repair
(warranty administration), on-site maintenance, third party maintenance,
consultation, logistics management, and 24-hour technical support via
telephone and the Internet. 

The Company's technical support organization consists of unique and
highly-trained teams that focus on customer support of the TITAN 5500 and
5300 series, CROSSNET 44X and 33X, CABLESPAN, Voice Frequency and Martis
DXX product lines.  All teams utilize a problem tracking system to capture,
collect and report on a number of data points specific to product
performance and overall customer profiles.  The technical support teams
also utilize a call director system to track the status of customers'
calls until completion. 

The Company provides product warranties for periods ranging from one to
five years for the repair or replacement of customer premises-located
modules and systems found to be faulty due to defective material.  Tellabs
has an expedited replacement service that is used to immediately provide
the customer with needed module replacements in response to a time-critical
service outage.

RESEARCH AND DEVELOPMENT 

The telecommunications industry continues to be characterized by rapid
technological change.  Historically, the technology of this industry had
been mainly analog, characterized by signals continuous in time with
information contained in the frequency and amplitude of the signals.  The
industry has rapidly shifted toward digital technology in which information
is coded in discrete pulses.  The Company's current product development
effort is directed almost entirely toward designing new products utilizing
digital, fiber optic and ATM technology.  The Company has also focused much
of its research and development efforts on large system software
development and associated processes. 

Many products used in network access system applications are well-suited to
the use of digital implementation techniques, including utilization of
microprocessors and other VLSI devices.  The Company's ability to combine
analog and digital technologies has been an important ingredient in its
product development.  The Company currently manufactures a number of
products using microprocessor control circuitry which make extensive use of
microprocessors and complex system software.  The Company is also
actively developing products which utilize high speed fiber optic
technologies to provide higher performance transmission characteristics in
today's telecommunication networks.  The Company is continually updating
its research and development capabilities through the addition of new
computer-aided design (CAD) and computer-aided software engineering (CASE)
tools, which assist in electronic, mechanical, and software design.  Use of
such tools is imperative as the Company seeks to respond to industry and
customer demands for intelligent digital systems and networking products
with capabilities for automated remote maintenance and provisioning. 

During 1996, the Company made two research and development-oriented
acquisitions designed at advancing and expanding the Company's existing
product portfolios and performance capabilities.  In the first, the
acquisition of Steinbrecher Corporation in April 1996, the Company expanded
its product offerings to include wireless communications infrastructure
products and systems for use in cellular and other wireless networks in
order to create a comprehensive wireless network offering from the
Company.  In the second acquisition, the Company acquired the broadband
access product line of TRANSYS Networks Inc in June 1996.  The move was
designed to provide the Company with broadband access and transport

                                   9 
technology that would complement the technology that already exists in its
TITAN line of SONET-based digital cross-connect systems.

In early January, 1997, the Company acquired wave-length division
multiplexing and optical networking technology from IBM's Thomas J. Watson
Research Center which included rights to or ownership of several patents
and patent applications and will compliment the Company's transport and
access product portfolio.  Under the terms of the agreement, the Research
Center's optical network development team joined the Company. 

The Company is also involved in product-oriented alliances.  In December
1996, the Company and AFC, a Petaluma, California-based provider of
next-generation digital loop carrier equipment, terminated the joint
venture agreement signed in April 1994, and entered into a licensing
agreement for the development, manufacturing, and marketing of the
CABLESPAN product. 

These acquisitions and alliances allow the Company access to technology
that is important to the future of its products.  In addition, to ensure
that the technologies the Company uses reflect the most recent industry
developments and to increase the Company's ability to develop new
technologies, the Company conducts research at its laboratories in
Mishawaka, Indiana; Burlington, Massachusetts; Espoo and Oulu, Finland; and
Shannon, Ireland. 

Research and development expenses were $107.3 million in 1996, $81.9
million in 1995, and $64.8 million in 1994.  (The 1996 research and
development expense does not reflect the $74.7 million one-time charge
for acquired research and development taken in conjunction with the
Steinbrecher acquisition.) The Company plans to spend approximately $150
million on research and development in 1997.  These expenditures reflect
the Company's commitment to the enhancement of existing products and
development of new products designed to satisfy the needs of communications
service providers worldwide. 

MANUFACTURING AND EMPLOYEES 

The Company assembles its products from standard components and from
fabricated parts which are manufactured by others to the Company's
specifications.  Such purchased items represented approximately 74 percent
of cost of sales in 1996. 

Most purchased items are standard commercial components available from a
number of suppliers with only a few items procured from a single-source
vendor.  Management believes that alternate sources could be developed for
those parts and components of proprietary design and those available only
from single or limited sources.  However, future shortages could result in
production delays that could adversely affect the Company's business. 

As part of the manufacturing process, hazardous waste materials that are
present are handled and disposed of in compliance with all Federal, State
and local provisions.  These waste materials and their disposal have no
significant impact on either the Company's production process or its
earnings or capital expenditures. 

At December 27, 1996, the Company had 3,418 employees, of which 732 were
employed in the sales, sales support and marketing area, 997 in product  
development, 1,385 in manufacturing, and 304 in administration.  The

                                   10 
Company considers its employee relations to be good.  It is not a party to
any collective bargaining agreement. 

TRADEMARKS, PATENTS AND COPYRIGHTS 

The Company has various trade and service marks, both registered and
unregistered, in the U.S. and in numerous foreign countries (collectively,
Marks).  All of these Marks are important in that they differentiate the
Company's products and services within the industry through brand name
recognition.  Current Marks of the Company include TELLABS, MARTIS, 310
Datavoice System, ACSYS, ALTA, AN2100, ASC, ATM to the Core, CABLESPAN,
CLEARCALL, CROSSNET, DATACELL, DATAPLEXER, DXX, DYNAMIC SIGNAL TRANSFER,

CORE, T-CODER, TELEMARK, TITAN, TURNING YOUR COPPER INTO GOLD, UNLOCK THE

not aware of any factor which would affect its ability to utilize any of
its major trademarks. 

The Company currently holds 25 U.S. and 3 Canadian patents.  The Company
has also developed certain proprietary, confidential hardware designs and
software programs.  The Company owns various rights, which are protectable
under copyright and trade secret laws, in such designs and programs. 

The Company believes that trademarks, patents, copyrights and trade secrets
are important to its business. 

BUSINESS SEGMENT AND GEOGRAPHICAL INFORMATION 

The Company operates in one business segment.  Information with respect to
the Company's operations in its two geographical areas for the fiscal
years ended December 27, 1996, December 29, 1995 and December 30, 1994,
is set forth in Note I on page 32 of the registrant's Annual Report to
Stockholders and is incorporated herein by reference. 

ITEM 2.  PROPERTIES 

The Company's corporate headquarters is located on 18-1/2 acres of
Company-owned land approximately 30 miles west of Chicago in Lisle,  
Illinois.  Located on this property are three buildings.  The first is a
65,000 square foot building that functions as the Company's headquarters
and houses a portion of the Digital Systems division's marketing and
engineering personnel.  The second is a 103,000 square foot building which
houses customer service, research and development and administrative
functions.  The third building is a 54,000 square foot building utilized by
the majority of the Digital Systems division's engineering operations. 

The Company also owns 50 acres of land in Bolingbrook, Illinois (near
Lisle) where a 230,000 square foot manufacturing, engineering and office
building was completed and occupied in July 1993.  During 1996, the Company
began construction of a new 308,000 square foot addition to this facility.
Construction of the addition is expected to be completed by mid-1997 at a
cost of approximately $33,000,000.  The new addition will provide for
necessary manufacturing capacity expansion as well as allowing additional
space for expansion of the sales and administrative functions. 


                                   11 


The Company also owns approximately 75 acres of land in Round Rock, Texas,
and approximately 2.6 acres of land in Mississauga, Ontario, Canada.  The
Texas property includes a recently expanded 125,000-square foot
manufacturing facility.  The Canadian property includes a 20,000-square
foot office/warehousing building.  The Company also owns three
office/manufacturing facilities in Espoo, Finland used as follows: a
52,000-square foot building which is currently being used for engineering,
marketing, and administrative offices; a 42,000-square foot production
facility; and a 35,000-square foot office building, which is currently used
for engineering offices.  In addition, approximately 12 acres of land were
purchased in April, 1996 in Espoo for the construction of a new
150,000-square foot production and engineering facility scheduled for
completion in December 1997.  Also existing on this property is a
100,000-square foot building (currently leased to a third party). 

The Company leases additional facilities at the following locations: Lisle,
Illinois (training); Naperville, Illinois (sales); Mishawaka, Indiana
(research); Costa Mesa, California (sales); Littleton, Colorado (sales);
Atlanta, Georgia (sales); Rockville, Maryland (sales); St. Louis, Missouri
(sales); Irving, Texas (sales); White Plains, New York (customer service);
and two buildings (90,000 square feet) in Burlington, Massachusetts for
sales, research, production and administration.  Some of the Company's
international subsidiaries also lease space for their operations,
including: a 56,000-square foot sales, research and production facility and
a 5,000-square foot administrative facility in County Clare, Ireland;
40,000 square feet in Espoo, Finland for administration and engineering,
and 15,000 square feet for production; and 12,000 square feet in Oulu,
Finland for research and development. 

The Company owns substantially all the equipment used in its business.  The
Company believes that its facilities are adequate for the level of
production anticipated in 1997, and that suitable additional space and
equipment will be available to accommodate expansion as needed.

The Company is not involved in any material litigation.

          TG from time to time as determined by Tellabs' Board of Directors
          or the Committee.  Each such grant shall be evidenced by a notice

          are made.  The maximum number of employees of Tellabs TG to whom
          Bonus Stock Awards may be granted however is 50.

     2.2  Terms of Bonus Stock Awards

          Bonus Stock Awards shall be subject to the following terms and
          conditions.

          a)   Number of Shares and Other Terms

          The number of shares of Common Stock subject to Bonus Stock Award
          granted to any one person pursuant to this Plan shall be no
          greater than 500, subject to adjustment as provided in Section 3.3 
          hereof.

          b.   Vesting and Forfeiture

          One-half of the number of shares of Common Stock subject to a
          Bonus Stock Award shall vest and be payable on the first

                                   2

          anniversary of the Closing Date and the other half of such number 
          shall vest and be payable on the second anniversary of the
          Closing Date, in each case, subject to Section 2.3 b), if the 
          holder of such award remains continuously in the employment of
          Tellabs or Tellabs TG until such anniversary date of the Closing
          Date.  Such holder shall forfeit the unvested portion of any such
          shares if such holder does not remain continuously in the
          employment of Tellabs or Tellabs TG as specified above, except as 
          otherwise provided in Section 2.3 b) hereof.

     c.   Share Certificates

          Upon the vesting of a portion of a Bonus Stock Award pursuant to
          Section 2.2 b), 2.3 b) or 3.5, in each case subject to Tellabs or
          Tellabs TG rights to require payment of any taxes in accordance
          with Section 3.2, a certificate or certificates evidencing
          ownership of the number of shares of Common Stock so vested shall 
          be delivered to and in the name of the holder of such award.
          Notwithstanding the foregoing, in lieu of the delivery of shares
          representing all or a portion of the vested portion of a Bonus
          Stock Award, the Committee may, in its sole discretion, deliver
          to the holder cash in an amount equal to the Fair Market Value on
          the date such shares become vested equal to the vested portion of
          such award, less any applicable withholding, as required by
          Section 3.2, as the case may be.

     d.   Price

          No payment shall be required or exigible by a recipient of a
          Bonus Stock Award or Common Stock pursuant to this Plan.  Bonus 
          Stock Awards and Common Stock issued pursuant to this Plan shall
          be granted by Tellabs as consideration for a recipient's having
          decided to remain as an employee of Tellabs TG following its
          acquisition by Tellabs.

     2.3  Termination of Employment.

     a.   Termination Resulting in Forfeiture

          If the employment with Tellabs or Tellabs TG of the holder of
          a Bonus Stock Award is (i) terminated by Tellabs or Tellabs TG
          for Cause, (ii) if such employment terminates by reason of the
          holder's Disability, or death, or (iii) if a holder voluntarily
          terminates his employment with Tellabs or Tellabs TG for any
          reason, the portion of such award which is not vested pursuant
          to Section 2.2(b) shall be forfeited by such holder and such
          portion shall be canceled by Tellabs.

     b.   Other Termination

          If Tellabs or Tellabs TG terminates the employment of the
          holder of a Bonus Stock Award for any reason other than Cause or
          Disability, the portion of such award which is not otherwise
          vested shall vest pursuant to Section 2.2(b) without regard to
          such termination.


                                   3


3.   GENERAL

     3.1  Amendments

          The Board may amend this Plan as it shall deem advisable,
          provided, however, that no amendment shall be made if such  
          amendment would increase the maximum number of shares of Common
          Stock available under this Plan (subject to Section 3.3).  No
          amendment may impair the rights of a holder of an outstanding  
          award without the consent of such holder.

     3.2  Tax Withholding

          Tellabs and Tellabs TG shall have the right to require, prior
          to the issuance or delivery of any shares of Common Stock or the
          payment of any cash pursuant to an award made hereunder, payment
          by the holder of such award of any federal, provincial, local or
          other taxes which may be required to be withheld or paid in
          connection with such award.  The Committee may allow shares of  
          Common Stock to be delivered or withheld having an aggregate Fair
          Market Value not in excess of the minimum amount required to be
          withheld.  Any fraction of a share of Common Stock which would be
          required to satisfy such an obligation shall be disregarded and
          the remaining amount due shall be paid in cash by the holder.

     3.3  Adjustment

          In the event of any stock split, stock dividend,
          recapitalization, reorganization, merger, consolidation,  
          combination, exchange of shares, liquidation, spin-off or other
          similar change in capitalization or event, or any distribution to
          holders of Common Stock other than a regular cash dividend, the
          number and class of securities available under this Plan, the
          number and class of securities subject to each outstanding Bonus 
          Stock Award shall be adjusted or modified accordingly, as
          determined by the Committee, which adjustment may include providing 
          for payment of an asset not constituting a security upon the
          vesting of an outstanding Bonus Stock Award.  The decision of the  
          Committee regarding any such adjustment shall be final, binding
          and conclusive.  If any such adjustment would result in a
          fractional security being (i) available under this Plan, such  
          fractional security shall be disregarded, or (ii) subject to an
          award under this Plan, Tellabs or Tellabs TG shall pay the holder
          of such award, in connection with the first vesting of such
          award, in whole or in part, occurring after such adjustment, an  
          amount in cash determined by multiplying (i) the fraction of such
          security (rounded to the nearest hundredth) by (ii) the excess,
          if any, of the Fair Market Value on the vesting date.

     3.4  Minimum Sum to be Collected

          Given that Bonus Stock Awards and Common Stock issued pursuant
          to this Plan without any payment being required or exigible, no
          minimum sum will be collected.  Bonus Stock Awards and Common
          Stock issued pursuant to this Plan shall be granted by Tellabs
          as consideration for a recipient's having decided to remain as
          an employee of Tellabs TG following its acquisition by Tellabs.

                                   4

     3.5  No Assignment

          It is a condition of this Plan, and the rights of all holders
          of Bonus Stock Awards shall be subject thereto, that no right or
          interest of any such holder shall be assignable or transferable
          in whole or in part, either directly or by operation of law or
          otherwise, including, but not by way of limitation, execution,
          levy, garnishment, attachment, pledge or bankruptcy, and no right
          or interest of any such holder under this Plan shall be liable
          for, or subject to, any obligation of any such holder, including
          claims for alimony or the support of any spouse.

     3.6  No Right of Employment

          Neither this Plan nor any award made hereunder shall confer upon
          any person any right to continued employment by Tellabs, Tellabs
          TG or any subsidiary or affiliate thereof or affect in any manner
          the right of Tellabs, Tellabs TG or any subsidiary or affiliate
          thereof to terminate the employment of any person at any time
          without liability hereunder.

     3.7  Right as Stockholder

          No person shall have any right as a stockholder of Tellabs with
          respect to any shares of Common Stock or other equity security of
          Tellabs which is subject to an award hereunder unless and until
          such person becomes a stockholder of record with respect to such
          shares of Common Stock or equity security.  Tellabs's obligation
          to deliver shares of Common Stock pursuant to this Plan shall be
          unfunded, and Tellabs shall not be obligated to set aside any of
          its assets for the purpose of satisfying its obligations
          hereunder.  The claims of holders of Bonus Stock Awards shall be  
          solely those of an unsecured creditor of Tellabs.

     3.8  Governing Law

          This Plan and each award hereunder, and all determinations made
          and actions taken pursuant hereto, to the extent not otherwise
          governed by the laws of the United States, shall be governed by
          the laws of the State of Delaware and construed in accordance
          therewith without giving effect to principles of conflicts of laws. 

     3.9  Effective Date

          This Plan shall have retroactive effect from the Closing Date
          following its approval by the Commission des valeurs mobilieres
          du Quebec.

     2.2  Terms of Bonus Stock Awards

          Bonus Stock Awards shall be subject to the following terms and
          conditions.

     a.   Number of Shares and Other Terms

          The number of shares of Common Stock subject to a Bonus Stock
          Award granted pursuant to this Plan shall be the number of such
          shares set forth opposite the name of such employee on Schedule
          A hereto.

     b.   Vesting and Forfeiture

          One-half of the number of shares of Common Stock subject to a
          Bonus Stock Award shall vest and be payable on the first
          anniversary of the Closing Date and the other half of such number 
          shall vest and be payable on the second anniversary of the

                                   2
          Closing Date, in each case, subject to Section 2.3(b), if the 
          holder of such award remains continuously in the employment of
          Tellabs or a Subsidiary until such anniversary date of the
          Closing Date.  Such holder shall forfeit the unvested portion of  
          any such shares if such holder does not remain continuously in
          the employment of Tellabs or a Subsidiary as specified above,
          except as otherwise provided in Section 2.3(b) hereof.

     c.   Shares Certificates

          Upon the vesting of a portion of a Bonus Stock Award pursuant
          to Section 2.2(b) or 2.3(b), in each case subject to Tellabs or
          a Subsidiary rights to require payment of any taxes in accordance
          with Section 3.2, a certificate or certificates evidencing
          ownership of the number of shares of Common Stock so vested shall  
          be delivered to and in the name of the holder of such award.
          Notwithstanding the foregoing, in lieu of the delivery of shares
          representing all or a portion of the vested portion of a Bonus
          Stock Award, the Committee may, in its sole discretion, deliver
          to the holder cash in an amount equal to the Fair Market Value on
          the date such shares become vested equal to the vested portion of
          such award, less any applicable withholding, as required by
          Section 3.2, as the case may be.

     2.3  Termination of Employment

     a.   Termination Resulting in Forfeiture

          If (i) employment with Tellabs or a Subsidiary of the holder of a
          Bonus Stock Award is terminated by Tellabs or a Subsidiary for
          Cause, (ii) such employment terminates by reason of the holder's
          Disability or death, or (iii) a holder voluntarily terminates his
          employment with Tellabs or a Subsidiary for any reason, the
          portion of such award which is not vested pursuant to Section 2.2(b) 
          shall be forfeited by such holder and such portion shall be
          canceled by Tellabs.

     b.   Other Termination

          If Tellabs or a Subsidiary terminates the employment of the
          holder of a Bonus Stock Award for any reason other than as provided  
          in Section 2.3(a), the portion of such award which is not
          otherwise vested shall vest pursuant to Section 2.2(b) without  
          regard to such termination and be payable within thirty (30) days
          of such termination, in accordance with Section 2.2(c).

3.   GENERAL

     3.1  Amendments

          The Board or the Committee may amend this Plan as it shall deem
          advisable, provided, however, that no amendment shall be made if
          such amendment would increase the maximum number of shares of
          Common Stock available under this Plan (subject to Section 3.3). 
          No amendment may impair the rights of a holder of an outstanding
          award without the consent of such holder.


                                   3     

     3.2  Tax Withholding

          Tellabs shall have the right to require, prior to the issuance
          or delivery of any shares of Common Stock or the payment of any
          cash pursuant to an award made hereunder, payment by the holder
          of such award of any federal, provincial, local or other taxes
          which may be required to be withheld or paid in connection with
          such award.  The Committee may allow shares of Common Stock to
          be delivered or withheld having an aggregate Fair Market Value
          not in excess of the minimum amount required to be withheld and
          in such event, any fraction of a share of Common Stock which
          would be required to satisfy such an obligation shall be
          disregarded and the remaining amount due shall be paid in cash  
          by the holder.

     3.3  Adjustment

          In the event of any stock split, stock dividend,
          recapitalization, reorganization, merger, consolidation,  
          combination, exchange of shares, liquidation, spin-off or other
          similar change in capitalization or event, or any distribution to
          holders of Common Stock other than a regular cash dividend, the
          number and class of securities available under this Plan, the
          number and class of securities subject to each outstanding Bonus 
          Stock Award shall be adjusted or modified accordingly, as
          determined by the Committee, which adjustment may include providing  
          for payment of an asset not constituting a security upon the
          vesting of an outstanding Bonus Stock Award.  The decision of the  
          Committee regarding any such adjustment shall be final, binding
          and conclusive.  If any such adjustment would result in a
          fractional security being (i) available under this Plan, such 
          fractional security shall be disregarded, or (ii) subject to an
          award under this Plan, Tellabs shall pay the holder of such
          award, in connection with the first vesting of such award, in whole  
          or in part, occurring after such adjustment, an amount in cash
          determined by multiplying (a) the fraction of such security
          (rounded to the nearest hundredth) by (b) the excess, if any, of  
          the Fair Market Value on the vesting date.

     3.4  No Assignment

          It is a condition of this Plan, and the rights of all holders
          of Bonus Stock Awards shall be subject thereto, that no right or
          interest of any such holder shall be assignable or transferable
          in whole or in part, either directly or by operation of law or
          otherwise, including, but not by way of limitation, execution,
          levy, garnishment, attachment, pledge or bankruptcy, and no right
          or interest of any such holder under this Plan shall be liable
          for, or subject to, any obligation of any such holder, including
          claims for alimony or the support of any spouse.

     3.5  No Right of Employment

          Neither this Plan nor any award made hereunder shall confer upon
          any person any right to continued employment by Tellabs, Tellabs
          Operations or any Subsidiary or affiliate thereof or affect in
          any manner the right of Tellabs, Tellabs Operations or any

                                   4 

          Subsidiary or affiliate thereof to terminate the employment of
          any person at any time without liability hereunder.

     3.6  Right as Stockholder

          No person shall have any right as a stockholder of Tellabs with
          respect to any shares of Common Stock or other equity security of
          Tellabs which is subject to an award hereunder unless and until
          such person becomes a stockholder of record with respect to such
          shares of Common Stock or equity security.  Tellabs' obligation
          to deliver shares of Common Stock pursuant to this Plan shall be
          unfunded, and Tellabs shall not be obligated to set aside any of
          its assets for the purpose of satisfying its obligations
          hereunder.  The claims of holders of Bonus Stock Awards shall be 
          solely those of an unsecured creditor of Tellabs. 

     3.7  Governing Law

          The corporate law of the State of Delaware shall govern all
          issues concerning the relative rights of Tellabs and the holders 
          of Bonus Stock Awards with respect to this Plan.  The law of the
          State of Illinois, except its law with respect to choice of law,
          shall be controlling in all other matters relating to the Plan.

     3.8  Effective Date

          This Plan shall become effective on the Closing Date.

Management Statement of Financial Responsibilities

The financial statements of Tellabs, Inc., and Subsidiaries have been
prepared under the direction of management in conformity with generally
accepted accounting principles.  In the opinion of management, the
financial statements set forth a fair presentation of the consolidated
financial condition of Tellabs, Inc., and Subsidiaries at December 27,
1996, and December 29, 1995, and the consolidated results of its operations
for the years ended December 27, 1996, December 29, 1995, and December 30,
1994.

The Company maintains accounting systems and related internal controls
which, in the opinion of management, provide reasonable assurances that
transactions are executed in accordance with management's authorization,
that financial statements are prepared in accordance with generally
accepted accounting principles, and that assets are properly accounted for
and safeguarded.

Ethical decision-making is fundamental to the Company's management
philosophy.  Management recognizes its responsibility for fostering a
strong ethical climate so that the Company's affairs are conducted to the
highest standards of personal and corporate conduct.  Employee awareness of
these objectives is achieved through key written policy statements.

The Board of Directors has appointed two of its non-employee members as an
Audit Committee.  This committee meets periodically with management and the
independent certified public accountants, who have free access to this
committee without management present, to discuss the results of their
audit work and their evaluation of the internal control structure and the
quality of financial reporting.

Report of Independent Certified Public Accountants

We have audited the accompanying consolidated balance sheets of
Tellabs, Inc., and Subsidiaries as of December 27, 1996, and
December 29, 1995, and the related consolidated statements of earnings,
stockholders' equity and cash flows for the years ended December 27, 1996,
December 29, 1995 and December 30, 1994.  These financial statements are
the responsibility of the Company's management.  Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free
of material misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial
statements.  An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating
the overall financial statement presentation.  We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Tellabs,
Inc., and Subsidiaries at December 27, 1996, and December 29, 1995, and the
consolidated results of its operations and its consolidated cash flows for
the years ended December 27, 1996, December 29, 1995 and December 30,
1994, in conformity with generally accepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note A: Summary of Significant Accounting Policies

Nature of Business 
Operating in one business segment, the Company and its Subsidiaries
design, assemble, market and service a diverse line of electronic
communications equipment used in public and private communications
networks worldwide.

Consolidation 
The consolidated financial statements include the accounts of the
Company and its Subsidiaries.  All significant intercompany balances and
transactions have been eliminated.  The results of the Tellabs Wireless
Systems Division and the Tellabs Transport Group are included since
their respective purchase dates of April 17, 1996, and June 28, 1996.
(See Note K.) 

Certain reclassifications have been made in the 1994 and 1995 consolidated
financial statements to conform to the 1996 presentation.  The presentation
of the consolidated financial statements requires the use of estimates by
management.

Cash Equivalents 
The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents.

Fair Value of Financial Instruments 
The Company's financial instruments include cash and cash equivalents,
marketable securities, cost-basis investments, and long-term debt.  The
carrying value of the cash and cash equivalents and long-term debt
approximates their estimated fair values based upon quoted market prices.
The fair value of investments in marketable securities is estimated based
on quotes from brokers or current rates offered for instruments with
similar characteristics.   
 
Inventories 
Inventories are stated at the lower of cost or market.  Cost is determined
by the first-in, first-out method.

Depreciation 
Depreciation is provided for in amounts sufficient to relate the cost of
depreciable assets to operations over their estimated service lives, on
both the declining-balance and straight-line methods.

Income Taxes 
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective
tax bases at enacted tax rates when such amounts are expected to be
realized or settled.

Goodwill 
On an ongoing basis, management reviews the valuation and amortization of
goodwill.  As part of this review, the Company estimates the value and
future benefits of the net income generated by the related subsidiaries to
determine that no impairment has occurred.  Goodwill is amortized over
both 20 and 10 years using the straight-line method.  The accumulated
amortization of goodwill is approximately $9,775,000 and $6,092,000 as of
December 27, 1996 and December 29, 1995, respectively. 
Note A: Summary of Significant Accounting Policies (continued)

Stock Awards  
The Company has a program to award shares of the Company's common stock
to employees in recognition of their past service.  Each full-time
employee who has worked for a continuous 5- or 20-year period is awarded
10 or 25 shares, respectively.  When an employee stock award is granted,
compensation expense is charged for the fair market value of the shares
issued.

Revenue Recognition 
The Company recognizes revenue at the date of shipment.

Earnings Per Share 
Earnings per share are based on the weighted average number of common and
common equivalent shares outstanding during each period along with the
dilutive effect of outstanding stock options.  On April 22, 1994, April 25,
1995, and October 24, 1996, the Company declared 2-for-1 stock splits
payable in the form of a 100 percent stock dividend.  All references to the
number of common shares and per share amounts have been retroactively
restated to give effect to the stock dividends.

Foreign Currency Translation 
The financial statements of the Company's subsidiaries are generally
measured using the local currency as the functional currency.  Accordingly,
the effect of translating a subsidiary's financial statements into U.S.
dollars is recorded as a separate component of stockholders' equity.

Foreign Exchange  
Gains and losses from changes in exchange rates are recognized in "Other
Income (Expense)".  Net losses of $273,000, $302,000 and $1,555,000 were
recorded in 1996, 1995 and 1994, respectively. 

Foreign Exchange Contracts 
The Company enters into foreign exchange contracts as a hedge against
net foreign accounts receivable and payable.  Market value gains and
losses on the contracts are recognized and are combined with offsetting
foreign exchange gains or losses on those accounts.

Note B: Investments

Available-for-sale marketable securities are accounted for at market with
the unrealized gain or loss net of deferred income taxes shown as a
separate component of stockholders' equity.  At December 27, 1996, and
December 29, 1995, they consisted of the following:

</TABLE>
Held-to-maturity securities are carried at their amortized cost.  During
1996, all such investments had matured.  At December 29, 1995, the
balance of $1,300,000, consisting entirely of U.S. government and
corporate debt obligations, was included in "Investments in Marketable
Securities". 

The Company has an investment in a company that had an initial public
offering (IPO) during 1996.  The Company has marked this investment to
market subject to the constraints of the security sale limitations of the
IPO.  Under these constraints, only those shares that can be traded within
the next year are included in "Investment in Marketable Securities" while
the remaining shares are included in "Other Assets" at their historical
cost. 

During 1996, the Company committed to make a $8,500,000 contribution to the
Tellabs Foundation.  The contribution will consist of stock from the
aforementioned investment.  Investments in marketable securities have been
reduced accordingly. 

In the ordinary course of managing its assets and liabilities, the Company
uses financial instruments, which are not reflected in the financial
statements, to reduce or eliminate its exposure to foreign exchange risks.
Foreign currency risk is managed through forward exchange contracts.



Note B: Investments (Continued)

The Company had forward exchange contracts, generally having maturities of
less than 120 days, in the amount of $57,409,000 and $41,914,000 at
December 27, 1996, and December 29, 1995, respectively.  These contracts
are primarily denominated in Finnish markka, Irish punts and Canadian
dollars. 


Note C:  Long-Term Debt

The long-term debt of $2,850,000 comprises industrial revenue bonds that
were issued on December 20, 1991, with the principal payable in October
2014.  Interest is payable quarterly based on a variable interest rate set
weekly based on market conditions for similar instruments.  The effective
rates for 1996, 1995 and 1994 were 3.51 percent, 3.94 percent and 2.88
percent, respectively.  The debt is unsecured.  The provisions of the loan
agreement contain restrictive covenants, including a minimum net worth and
debt-to-equity ratio.


Note D:  Stock Options

At December 27, 1996, the Company had seven stock-based compensation plans,
which are described below.  The Company applies APB Opinion 25 and its
related interpretations in accounting for its plans.  No compensation cost
has been recognized for its fixed stock option plan grants.  Had
compensation cost for the Company's stock-based compensation plans been
determined using the fair value at the grant dates for awards under those
plans consistent with the method of FASB Statement 123, the Company's net
income and earnings per share would have been reduced to the pro forma
amounts indicated below:

</TABLE>

The fair value of each option is estimated on the date of grant using the
Black-Scholes option pricing model with the following weighted-average
assumptions used for grants in 1996 and 1995, respectively: dividend yield
of zero percent for both years; expected volatility of 51.2 percent and
52.4 percent; risk-free interest rates of 5.26 percent to 6.65 percent and
5.25 to 7.88 percent; and expected lives of 2.53 years to 5.53 years and
2.6 years to 5.6 years. 

The Company's 1981 Incentive Stock Option Plan is a tax-qualified plan that
provided for 4,320,000 shares of common stock to be reserved for options
issued under the plan.  No grants have been made under the 1981 Plan since
its expiration on November 24, 1991.  At December 29, 1995, all shares
that had been granted under the 1981 Plan had been exercised or cancelled. 
Note D:  Stock Options (continued)

The Company's 1984 Incentive Stock Option Plan is a tax-qualified plan that
provides for 4,800,000 shares of common stock to be reserved for options
that may be issued under the plan.  The plan also provides that the option
price shall be the market value of the shares as of the date of grant,
except for options granted to holders of 10 percent or more of the
outstanding shares, in which case the option price shall be 110 percent of
the market value of the shares as of the date of grant. 

The Company's 1986 Non-Qualified Stock Option Plan provides for 12,000,000
shares of common stock to be reserved for options that may be issued under
the plan.  The plan provides that the option price shall be the market
value of the shares as of the date of grant.   

The Company's 1987 Stock Option Plan for Non-Employee Corporate Directors
provides for the non-discretionary grant of options to non-employee
directors of the Company to purchase a combined maximum of 1,200,000
shares of common stock of the Company at a per-share price not less than
the market value per share of the common stock on the date of grant.  The
plan provides that each non-employee director, on the date such person
becomes a non-employee director, will be granted options to purchase 10,000
shares of common stock and, provided such person is still serving as a
non-employee director, will automatically be granted options to purchase
6,000 additional shares of common stock each year thereafter on the
anniversary of the last day of the month in which the initial options were
granted.  Options granted under the 1987 plan expire five years from the
grant date.

The Company's 1989 Stock Option Plan provides for 12,000,000 shares of
common stock to be reserved for options under the plan.  The plan allows
grants to employees of incentive or non-qualified options for up to
12,000,000 shares and up to 12,000,000 stock appreciation rights (SARs).
The SARs may be granted in conjunction with, or independently of, the
options under the plan.  The plan provides that the option price and the
SAR price shall be the market value of the Company's shares as of the date
of grant.  At December 27, 1996, 1,524,000 SARs with grant prices ranging
from $0.75 to $1.08 and 5-year terms and 786,220 SARs with a grant price
of $1.58 and $28.63 and 10-year terms had been granted.  At that date, a
total of 2,094,000 SARs had been exercised and 15,400 had been cancelled,
leaving 200,820 outstanding.

The Company's 1991 Stock Option Plan provides for 6,000,000 shares of
common stock to be reserved for options under the plan.  The plan allows
grants to employees of incentive or non-qualified options for up to
6,000,000 shares.  The plan provides that the option price shall be the
market value of the Company's shares as of the date of grant.

The Company's 1994 Stock Option Plan provides for 8,000,000 shares of
common stock to be reserved for options under the plan.  The plan allows
grants to employees of incentive or non-qualified options for up to
8,000,000 shares.  The plan provides that the option price shall be the
market value of the Company's shares as of the date of grant.   

In July 1996, the Company began a Global Option Program under which all
full-time employees below the director level as of July 8, 1996, were
granted non-qualified options or SARs to purchase 400 shares plus 20 shares
for each year of service.  The grants were dated July 22, 1996, with a
price of $28.63.  The options were granted from the 1994 Plan and the SARs
from the 1989 Plan. 
Note D:  Stock Options (continued)

Unless the option agreements provide otherwise, options or SARs granted
under the 1981, 1984, 1986, 1989, 1991, and 1994 plans become exercisable
on a cumulative basis at a rate of 25 percent on each of the second through
fifth anniversaries of the grant date.  Unless the option agreements
provide otherwise, options under the 1981 and 1986 plans terminate at the
end of 5 years after the grant while options or SARs granted under the
1984, 1989, 1991, and 1994 plans terminate at the end of 10 years after the
grant.

Note E: Employee Benefit and Retirement Plans

The Company maintains a defined contribution 401(k) retirement plan for the
benefit of eligible employees.  Under the plan, a participant may elect to
defer a portion of annual compensation.  Matching contributions equal to
the first 3 percent of annual compensation were made by the Company for
all eligible participants.  The Company may contribute additional amounts
at the discretion of the Board of Directors.  Company contributions to the
plan were $6,035,000, $4,707,000, and $3,480,000 in 1996, 1995 and 1994,
respectively.  Contributions to the plan are immediately vested in plan
participants' accounts.

The Company maintains a deferred compensation plan that permits officers
and certain management employees to defer portions of their compensation.
Unless the plan is amended by the Company, the deferred amounts earn an
annual interest rate of 12 percent during the term of the plan.  The
liabilities for the deferred salaries plus interest are included in "Other
Long-Term Liabilities".

The Company maintains money purchase and profit sharing plans for the
benefit of eligible employees.  Under the plans, 4 percent of eligible
annual compensation was contributed by the Company for each participant. No
part of the contribution is vested until after a service period of five
years, at which time the participant is fully vested.  Company
contributions to the plan were $4,056,000, $3,451,000, and $3,134,000 for
1996, 1995 and 1994, respectively.

Note G: Income Taxes (continued)

The net deferred income tax liability increased to $16,990,000 at
December 27, 1996, from $3,301,000 at December 29, 1995.  The increase of
the deferred tax balance is attributable to deferred taxes provided on the
mark-to-market adjustment on investments in accordance with FASB 115 and
the intangibles associated with the acquisition of the Wireless Systems
Division offset by a net operating loss also attributable to the acquisition. 

The Company recorded deferred tax assets for research and development
credits and net operating loss carryovers associated with the acquisition
in the amount of approximately $21,100,000.  A valuation allowance is
provided when it is more likely than not that some portion of the
deferred tax asset will not be realized.  The Company has established a
valuation allowance of $13,300,000 associated with the net operating
losses and research and credit carryovers of the acquisition.  The net
operating loss carryforwards and research and development tax credits
will expire at various dates through the year 2010.  If the Company
utilizes these carryforwards, they will be recognized as a reduction of
goodwill. 

Deferred U.S. income taxes are not provided on the undistributed
cumulative earnings of foreign subsidiaries because such earnings are
considered to be permanently invested in those operations.  The cumulative
earnings of foreign subsidiaries were approximately $173,549,000 at
December 27, 1996.  The amount of unrecognized deferred tax liability for
undistributed cumulative earnings of foreign subsidiaries at December 27,
1996, was approximately $28,893,000.




Note H: Major Customers

No single customer accounted for more than 10 percent of consolidated net
sales in 1996 and 1995.  A single customer accounted for approximately
15.3 percent of consolidated net sales in 1994.

Operating profit is net sales less all related costs of sales, marketing,
research and development, general and administrative and goodwill
amortization, excluding interest and income taxes.  Identifiable assets
are those assets considered as necessary for the ongoing activities and
operations of each geographic area.

Intergeographic sales are accounted for as sales and as cost of sales
between the domestic parent and its subsidiaries.  The sales price or cost
is dependent upon the product, consists of a discount from list price and
is sufficient to recover cost plus an appropriate markup for profit.

North American operating revenues include export sales to unaffiliated
customers of approximately $23,722,000, $33,105,000, and $31,018,000 in
1996, 1995, and 1994, respectively. 

Note J: Commitments

primarily involving office space, buildings and office equipment.  These
leases are non-cancellable and expire on various dates through 2009.

As of December 27, 1996, future minimum lease commitments under
non-cancellable operating leases are as follows:

$2,782,000, respectively.




Note K: Business Acquisitions

In April 1996, the Company acquired all of the outstanding shares of
Steinbrecher Corporation for approximately $77,000,000, financed with bank
loans and cash.  This acquisition has been accounted for through the use of
the purchase method of accounting, and, accordingly, the accompanying
financial statements include the results of its operations since the
acquisition date.  Goodwill arising from this acquisition of approximately
$6,865,000 is being amortized over 10 years. 

The following table summarizes on an unaudited pro forma basis the combined
results of operations of the Company as though the above acquisition were
made at December 31, 1994.  The pro forma amounts give effect to
appropriate adjustments to amortize goodwill, intangible assets and
acquisition costs and to reflect the reduction of interest income
resulting from the use of cash for the acquisition; the increase in
interest expense on the acquired bank debt; and, the corresponding income
tax effects.  In accordance with the Company's practice, in-process
research and development as well as its deferred income tax effects (a net
amount of approximately $54 million) was written of as reflected in the
1995 pro forma results presented below.

The pro forma financial information presented above does not purport to be
indicative of either the results that would have occurred had the
acquisition taken place at the beginning of the period presented or of
future results of operation of the combined businesses. 

In June 1996, the Company through the Tellabs Transport Group acquired
TRANSYS Network's SONET product line for approximately $17,000,000 in cash.
This acquisition has been accounted for through the use of the purchase
method of accounting, and, accordingly, the accompanying financial
statements include the results of its operations since the acquisition
date.  Goodwill resulting from this acquisition, in the amount of
$15,799,000, is being amortized over 10 years.  This acquisition did not
have a material impact on the Company's financial results. 

Subsequent to year end, the Company acquired, for $6,000,000 in cash,
certain wavelength-division multiplexing and optical networking
technology, including the rights to or ownership of several patents and
patent applications, from IBM's Thomas J. Watson Research Center.  Under
the terms of the agreement, the Research Center's optical network
development team joined the Company. 

In conjunction with each of the above acquisitions, a stock bonus plan was
established under which certain acquired employees are entitled to a
specific number of shares of the Company's stock over a two-year vesting
period. 



































MANAGEMENT'S DISCUSSION AND ANALYSIS

RESULTS OF OPERATIONS 

1996 vs. 1995

Sales during 1996 reached an all-time high as they climbed to
$868,975,000, surpassing 1995's previous record sales of $635,229,000.  The
1996 sales growth of 36.8 percent was driven by increased sales on both the
domestic and international fronts.  Domestic sales grew by 46 percent,
primarily as the result of the continuing strong sales of the TITAN (a
registered trademark of Tellabs Operations, Inc.) 5500 digital
cross-connect system.  International sales, which grew by 21 percent, were
driven by the Martis DXX (a trademark of Martis Oy, a subsidiary of
Tellabs, Inc.) managed access and transport system. 

Digital cross-connect sales for 1996 of $479,174,000 represent an
increase of $179,041,000 over those of the previous year.  Sales of the
Titan 5500 digital cross-connect system grew by 69 percent and continue to
drive this product group primarily through higher sales to existing local
exchange customers and the addition of a new major interexchange carrier.
These service providers seek to enhance their competitive advantage by
providing more robust networks to meet the needs of business customers, the
increasing demands of Internet traffic, and the desire for enhanced data
and video services.  The digital cross-connect group accounted for
approximately 57 percent of total product sales as it continues to lead all
product groups. 

The managed digital networks area exceeded last year's sales by almost 33
percent, reaching $231,602,000.  The continued expansion of DXX system
sales outside the Scandinavian market in response to growth in
infrastructure helped drive its $70,979,000 increase in sales during 1996,
reaching a new annual record of $201,198,000.  As was expected, the
remaining products in this group, such as the CROSSNET (a registered
trademark of Tellabs Operations, Inc.) data multiplexer and 33X packet
switch products, experienced decreases in their sales over those of the
previous year. 

Sales of network access products, which include analog voice-frequency
products, digital echo cancellers and digital transcoders, fell short of
the previous year's sales for the first time since 1991, although sales of
digital echo cancellors reached an all-time high.  This product group
continues to decrease as a percent of total product sales as the Company
concentrates its efforts on providing larger value-added system solutions
to its customers. 

Net earnings for 1996 were a record $117,965,000, up 2.0 percent from 1995
earnings of $115,606,000.  This slight increase in earnings was the net
effect of the significant increase in sales during 1996 being offset by
the one-time, net-of-tax charge of $54,100,000 for acquired in-process
research and development related to the acquisition of the Wireless
Systems Division (see Note K) and increased operating expenses and income
taxes.  Earnings per share were 64 cents in 1996, compared with 63 cents in
1995.  (The earnings-per-share amounts for both years are adjusted to
reflect the effect of the 2-for-1 stock splits that occurred in November
1996 and May 1995.) 

Sales during the fourth quarter of 1996 were a record $272,906,000,
consistent with the Company's typically strong fourth-quarter sales
pattern.  Sales of the TITAN 5500 system and DXX system led the 50.5
percent sales increase over the 1995 fourth quarter.  Net earnings for the
quarter were $59,399,000, a 55.9 percent increase over 1995 earnings of
$38,106,000.  Earnings per share were 32 cents for the fourth quarter of
1996 and 21 cents for the fourth quarter of 1995.  (The earnings-per-share
amounts for both years are adjusted to reflect the effect of the 2-for-1
stock splits that occurred in November 1996 and May 1995.) 

The gross profit margin for 1996 improved again to a new record level of
59.8 percent versus the previous record 57.3 percent achieved in 1995.
This improvement reflects both the sales of higher-margin products,
including software sales and hardware expansions, and the benefits provided
by the Company's highly productive and efficient manufacturing operations.
It will once again be a challenge to sustain the gross profit margin at
this record-setting level. 

Excluding the one-time charge to earnings for the acquired in-process
research and development, operating expenses increased 33.0 percent
during 1996.  During the year, new items such as the expenses of the
Wireless Systems Division and the Transport Group and the cost of the
enterprise-wide business system conversion were included in operating
expenses.  Headcount and related expenses grew to support and service
international and domestic products while additional expenses related to
employee compensation programs were incurred.  As a percentage of sales,
total 1996 operating expenses (excluding the one-time charge) decreased to
31.7 percent as compared to 32.6 percent in 1995 while each expense
category as a percentage of sales decreased from the prior year as has
occurred since 1993. 

Interest income increased to $7,371,000 in 1996, a 25.9 percent increase,
compared with $5,855,000 in 1995.  This increase was due to higher
average cash balances throughout the year as well as a shift in
investment holdings from federally tax-free municipal bonds to fully
taxable investments.  Interest expense for 1996 of $1,173,000 increased
by $1,049,000 from 1995 expense of $124,000.  The expense incurred in 1996
was primarily related to the bank debt used to partially finance the
Wireless Systems Division acquisition.  The debt was entirely repaid by the
fourth quarter of 1996. 

The effective tax rate was approximately 32.7 percent for 1996 and 29
percent for 1995.  The increase in the effective tax rate for 1996 is
primarily due to the tax effects of the in-process research and development
one-time charge taken in conjunction with the Wireless Systems Division
acquisition and the increase in domestic taxable income being partially
offset by the tax benefits received as a result of the $8,500,000
charitable contribution made to the Tellabs Foundation.  The 1996 effective
rate reflects adjustments from the federal statutory rate attributable to
the benefits of foreign tax rates, the merger of Finnish subsidiaries, the
charitable contribution, and tax credits offset by state taxes and the
one-time charge. 
              
1995 vs. 1994

Sales during 1995 hit a then-record high as they exceeded the
half-billion-dollar mark to reach $635,229,000 versus $494,153,000 in 1994.
The 1995 sales growth of 28.5 percent was representative of both the
continued strength and acceptance in the domestic marketplace of the TITAN
5500 digital cross-connect system and the growth of the Company's leading
international product, the DXX managed access and transport system.  Each
of these products addresses a different geographic marketplace, which
provided for growth of 24 percent domestically and 38 percent
internationally.  Additionally, all of the major product groups posted
gains over 1994 sales, as was the case in the prior two years. 
                                                              
Digital cross-connect sales for 1995 reached the $300,000,000 mark, with an
increase of almost $81,000,000 over those of the previous year.  Sales of
the Titan 5500 digital cross-connect system grew by 46 percent and
continued to drive this product group.  By the end of 1995, the Titan 5500
system was standard in all but one of the major local exchange carriers and
in most of the interexchange carriers in North America.  The digital
cross-connect group accounted for approximately 49 percent of total product
sales as it continued to lead all product groups. 

The managed digital networks area exceeded 1994's sales by 34 percent in
1995.  The acceptance of the DXX system in the international marketplace
and agreements with Ericsson helped drive its $53,000,000 increase in sales
during 1995.  As was expected, the remaining products in this group, such
as the CROSSNET data multiplexer and 33X packet switch products,
experienced decreases in their sales over those of the previous year. 

Sales of network access products, which include analog voice-frequency
products, digital echo cancellers and digital transcoders, exceeded the
previous year's sales in each of the last five years, even though they
continued to decrease as a percent of total product sales.  Sales of the
digital products within this group continued to grow as the products are
incorporated into cellular networks.  However, sales of the analog
products continued to decline as customers migrate to digital technology. 

Net earnings for 1995 were $115,606,000, up 59.7 percent from 1994
earnings of $72,389,000.  Earnings per share were 63 cents in 1995,
compared with 40 cents in 1994.  (The earnings-per-share amounts for both
years have been adjusted to reflect the effect of the 2-for-1 stock
splits that occurred in November 1996, May 1995 and May 1994.) This
significant increase in earnings was primarily due to the increase in sales
during 1995 and a corresponding 34.7 percent increase in gross profit
dollars.  Although operating expenses exceeded 1994's total, they continued
to decrease as a percentage of sales. 

Sales during the fourth quarter of 1995 were a then-record $181,324,000,
consistent with the Company's typically strong fourth-quarter sales
pattern.  Sales of the TITAN 5500 system and DXX system led the 22
percent sales increase over the 1994 fourth quarter.  Net earnings for the
quarter were $38,106,000, a 46.1 percent increase over 1994 earnings of
$26,075,000.  Earnings per share were 21 cents for the fourth quarter of
1995 and 14 cents for the fourth quarter of 1994.  (The earnings-per-share
amounts for both years are adjusted to reflect the effect of the 2-for-1
stock splits that occurred in November 1996 and May 1995.) 

The gross profit margin for 1995 improved significantly to a then-record
level of 57.3 percent versus 54.6 percent in 1994.  This improvement
reflects both the sales of higher-margin products, including a small amount
of higher-margin software sales, and the continuation of highly productive
and efficient manufacturing operations.  

Total operating expenses increased 21.6 percent during 1995, an increase
that was evenly divided between marketing and research and development.
Marketing expenses increased 27.5 percent due to headcount-related
expenses, international marketing activities, and customer support and
service expenses.  Research and development expenses increased 26.4 percent
due to increased headcount-related expenses in support of planned
enhancements to the Company's domestic and international product base.  As
a percentage of sales, total 1995 operating expenses were 32.6 percent
compared to 34.5 percent in 1994.  Each category as a percentage of sales
decreased from 1994. 

Interest income increased to $5,855,000 in 1995, an 83.8 percent increase
compared with $3,185,000 in 1994.  This was the result of
interest-bearing investments more than doubling during 1995.  Interest
expense for 1995 of $124,000 decreased by $1,649,000 from 1994 expense of
$1,773,000.  The expense incurred in 1994 was primarily related to the
bank debt used to finance the acquisition of Martis Oy.  The debt was
entirely repaid by the fourth quarter of 1994. 

Other income in 1995 was $441,000, of which foreign exchange losses of
$302,000 were the result of the strength of the Finnish markka and the
Irish punt versus the U.S.  dollar.  The significantly higher foreign
exchange losses of $1,555,000 in 1994 were primarily the result of the
strength of the Finnish markka versus the Swedish krona, U.S. dollar and
other European currencies to which the Company has exposure. 

Other income also includes the write-down of the Company's investment in
Advanced Access Labs, a joint venture between Advanced Fibre
Communications, Inc. (AFC) and the Company by which the two companies
combined their efforts in the local loop transport area to develop the
CABLESPAN (a registered trademark of Tellabs Operations, Inc.) 2300 system.
The investment was written down to reflect the Company's share of the
losses of the joint venture in accordance with the equity method of
accounting.  The equity in cumulative losses of the joint venture increased
to $2,000,000 by the end of 1995 from $1,012,000 at the end of 1994.
 
The effective tax rate was approximately 29 percent for 1995 and 26 percent
for 1994.  The increase in the effective tax rate for 1995 was primarily
due to the reduction of research and development tax credits and reduced
foreign tax rate benefits.  The 1995 effective rate reflected adjustments
from the federal statutory rate attributable to foreign tax rate benefits. 

LIQUIDITY AND CAPITAL RESOURCES 

The Company has never paid a cash dividend, and current policy is to retain
earnings to provide funds for the operation and expansion of the business.
The Company does not anticipate paying cash dividends in the foreseeable
future.

Net working capital at December 27, 1996, was $343,840,000, compared with
working capital of $267,806,000 at December 29, 1995.  The Company's
current ratio at December 27, 1996 was 3.6 to 1.  The increase in net
working capital is primarily the result of the Company's record earnings
being offset by the use of cash and cash equivalents to partially finance
the Company's second-quarter acquisitions.  Management believes this level
of working capital will be adequate to meet the Company's liquidity needs
related to normal operations both currently and in the foreseeable future.
Sufficient resources exist to support the Company's growth either through
currently available cash, through cash generated from future operations, or
through additional short-term or long-term financing. 

Operating activities provided the Company with a significant amount of cash
due to net earnings of $117,965,000.  Net trade accounts receivable
increased by $40,363,000 to a year-end balance of $167,928,000, due
primarily to the record-level sales volume in the fourth quarter of 1996.
Total inventory levels increased by $10,804,000 from 1995 levels due to
1997 sales forecast requirements for digital cross-connect systems and
the inventory purchased in the Wireless Systems Division acquisition.  The
inventory turnover ratio increased to 4.8 times from 4.5 times in 1995. 

Goodwill increased by $19,827,000 principally as a result of the Transport
Group and Wireless System Division acquisitions.  Other assets increased by
$17,113,000 primarily due to $18,216,000 worth of developed research and
development acquired in the Wireless Systems Division acquisition.  Accrued
liabilities increased from the 1995 balance by $19,194,000 primarily as a
result of the year-end obligations related to employee compensation
programs and the liabilities assumed as part of the acquisitions.  The
increase in the Company's liability for deferred income taxes of $9,881,000
reflects the future obligations related to the unrealized gains on
marketable securities as of year end. 

The Company's holdings in marketable securities increased by $66,670,000.
Approximately $43,648,000 is due to the mark-to-market adjustment of an
investment in a certain company that had an initial public offering during
1996.  The Company also invested approximately $64,831,000 during 1996 in
property, plant and equipment (exclusive of acquisitions) as additions were
made primarily to increase manufacturing capacity and expand research and
development efforts worldwide. 

The Company utilized $40,000,000 of bank debt to finance the acquisition
of the Wireless Systems Division.  This debt was entirely repaid by the end
of year.  Finally, an additional $22,480,000 of cash was provided to the
Company through the exercise of stock options under the Company's stock
option plans.

OUTLOOK 

Driven by sales growth in both the international and domestic markets,
sales for 1997 are expected to reach $1 billion for the first time in the
Company's history.  Domestic growth continues to be dependent upon the
continued strength of TITAN 5500 system sales.  International growth will
be primarily driven by sales of the DXX system.  In addition, late 1997
should see the introduction of several new products related to the 1996
acquisitions.  At December 27, 1996, backlog increased to approximately
$118,000,000 from $84,000,000 at the end of the prior year.  All of the
1996 backlog is expected to be shipped in 1997.  The Company considers
backlog to be an indicator, but not the sole predictor, of future sales.

During 1997, the Company will continue to focus on providing the
resources to support revenue growth in the most cost-effective method
possible.  To that end, total operating expenses for 1997 are expected to
average approximately 31 percent of planned revenues.  Research and
development expenses are expected to maintain an average of approximately
13 percent of sales, consistent with 1996 and 1995 percentages.  Marketing
and general and administrative expenses are expected to decrease by
almost 2 percent to approximately 17 percent of sales.  Management believes
these levels can be attained while supporting the sales and product growth
slated for 1997 and beyond as the Company continues to invest in its
future.

The 1997 capital expenditure plan totals approximately $96,000,000.  It is
anticipated that 1997 working capital requirements and capital expenditures
will be met with funds currently on hand and funds generated by future
earnings.  Earnings for 1997 are expected to be taxed at a 34 percent rate. 

The Company believes that the formation of business relationships with
compatible organizations is important to future growth in that it allows
the Company the opportunity to share in the development of new markets,
products and technologies.  It is for this reason that the Company will
continue to pursue the establishment of such relationships.
