Item 9. Regulation FD Disclosure.

     On May 2, 2001, officers of JDS Uniphase Corporation, a Delaware
corporation (the "Registrant"), delivered  an investor presentation that
included written communication comprised of slides which were described and
filed as Exhibit 99.1 to the Report on Form 8-K filed on May 4, 2001 and
incorporated therein by reference. Slide 42 of such slides which related to
"April 24 Guidance" for Q4 contained two typographical errors. "E.P.S. $.14,"
"$.15 steady state @ $700 million in sales" should have been "E.P.S. $.05,"
"$.06 steady state  @ $700 million in sales." Such corrected information as to
pro forma "E.P.S." and "steady state" is in each case as previously stated in
the Report on Form 8-K filed on April 24, 2001 that included the script and
press release from JDS Uniphase Corporation's third quarter results and
conference call.
