Nepean, Ontario, San Jose, Calif., and Santa Rosa, Calif., January 24, 2000- JDS Uniphase Corporation (Nasdaq: JDSU and TSE: JDU) today announced the first shipment of 10 Gb/s transmitter and receiver modules to meet customers' growing demand for products with higher functionality.

In addition, JDS Uniphase is expanding its line of 10 Gb/s transmitter and receiver modules with versions that support short distance, intermediate reach, and long reach applications. The module line is expected to include transmitter/receiver pairs with a built-in multiplex and demultiplex capability that simplifies system-level design, since system designers no longer need to deal directly with 10 Gb/s signals. This broad offering of 10 Gb/s modules is expected to give communications system designers flexibility in selecting the optimum system solution and reduce development time, thus enabling faster time-to-market on 10 Gb/s system products.

"We are pleased to be one of the first companies to provide our customers with 10 Gb/s module technology," said Kevin Kalkhoven, JDS Uniphase Co-Chairman and CEO. "Providing our customers with 10 Gb/s products that provide a higher level of functionality is key to enabling them to meet their time-to-market challenges."

JDS Uniphase is a high technology company that designs, develops, manufactures and distributes a comprehensive range of products for the growing fiberoptic communications market. These products are deployed by system manufacturers worldwide to develop advanced optical networks for the telecommunications and cable television industries. JDS Uniphase Corporation is traded on the Nasdaq National Market under the symbol JDSU and the exchangeable shares of JDS Uniphase Canada Ltd. are traded on The Toronto Stock Exchange under the symbol JDU.
