EXHIBIT 5.1
OPINION OF COUNSEL
June 15, 2000
Ladies and Gentlemen:
I have examined the Registration Statement on Form S-3 filed by JDS
Uniphase Corporation, a Delaware corporation (the "Company"), with the
Securities and Exchange Commission on June 15, 2000 (the "Registration
Statement") relating to the registration under the Securities Act of 1933,
as amended, of up to 183,930,633 shares (the "Shares") of the
Company's common stock, $.001 par value per share (the "Stock"). As
counsel to the Company, I have examined the proceedings taken by the Company in
connection with the registration of the shares of the Stock. It is my opinion
that, when issued, the shares of Stock that may be sold pursuant to the
Registration Statement will be legally and validly issued, fully paid and non-
assessable. I consent to the use of this opinion as an exhibit to the
Registration Statement and further consent to all references to this opinion in
the Registration Statement, the prospectus constituting a part thereof and any
amendments thereto.
Very truly yours,
/s/ Christopher S. Dewees
Corporate Counsel
