SAN JOSE, CALIFORNIA, June 1, 2005 – JDS Uniphase Corporation (NASDAQ: JDSU; and TSX: JDU) announced today that BellSouth Corporation, a Fortune 100 company and one of the largest communications companies in the U.S., has selected the company’s WaveReady™ platform for passive optical transport in the loop portion of its next-generation broadband network. The WaveReady optical subsystems will enable the delivery of next-generation services in addition to serving as a new platform for Wavelength Division Multiplexing (WDM). Shipment of the subsystems are expected to begin within the next year.

“The JDS Uniphase passive optical technologies will be a key component in allowing us to economically get Gigabit Ethernet from the Edge Aggregation Router to the IP-DSLAM,” said Bill Smith, chief technology officer of BellSouth. “In cases where we do not have a dedicated fiber available because the fiber is already in use, the CWDM approach will allow multiple wavelengths of light to share the fiber.”

The WaveReady WDM optical multiplexing subsystems are reliable, cost effective solutions for fiber exhaust and multiservice applications. They multiply the capacity of existing single mode fiber, by combining up to eight ITU-T G.694.2 compatible channels into a single optical fiber.

“BellSouth is leading the market in the deployment of the next breed of broadband services and is therefore raising the bar in network architecture flexibility,” said Tom Znotins, vice president of JDS Uniphase’s Subsystem Products Group. “Our long relationship with BellSouth and the selection of our WDM subsystems highlights both the multiservice capabilities of our platform as well as its high reliability characteristics.”

The WaveReady subsystems are NEBS qualified and designed to operate reliably under remote office environmental conditions. With millions of field operating hours, JDS Uniphase's industry-leading optical multiplexing technology offers unparalleled  reliability.
