MILPITAS, Calif. -- JDSU (Nasdaq: JDSU - News; TSX: JDU - News) today announced that its Board of Directors has approved a 1-for-8 reverse split of its common stock, following approval by the Company's stockholders on December 1, 2005. The reverse stock split will be effective at 11:59 pm, Eastern Time, on Monday, October 16, 2006. JDSU's common stock will begin trading on the NASDAQ on a split adjusted basis when the market opens on Tuesday, October 17, 2006, under the temporary trading symbol "JDSUD". The trading symbol will revert to "JDSU" after approximately twenty trading days.

Furthermore, proportional adjustments will be made to JDSU stock options and other equity incentive awards, equity compensation plans and convertible notes.
