Uniphase Announces New High Power 1310-nm CATV Transmitters; Introducing +14 dBm Output Power, the Industry's Highest Power.

SAN DIEGO, Calif.--(BUSINESS WIRE)--Feb. 23, 1999--Uniphase Corporation (Nasdaq:UNPH) today announced its new line of 1310-nm laser transmitter products for CATV applications. This new product family is designed for use by cable TV equipment manufacturers in their hybrid fiber coax product offerings that are delivering high bandwidth to the home.

These transmitters offer state-of-the-art performance and a compact design to allow for the high rack densities required by today's systems. "Uniphase has extensive experience using predistortion technology to linearize 1550-nm transmitters for CATV, so it was natural to apply these skills to the 1310-nm transmitters as well," said Eitan Gertel, Vice President and General Manager of the Uniphase Transmission Systems Division. Predistortion is a key technology enabling CATV transmission over fiber. "While we have manufactured 1310-nm transmitters on a custom product basis for some time, these products are our first standard product offering at 1310 nm," Gertel continued.

The Uniphase line of predistorted 1310-nm transmitters offers industry-leading performance in either a board level or complete transmitter configuration. They are available with powers up to +14 dBm, making them the highest power products in their class. They also include the hybrid amplifier, which is linearized along with the laser for maximum performance. These products are available for 77-channel and 110-channel plans used in North America, as well as other standard channel plans.

"We are very excited to be expanding our line with this new product. It represents Uniphase's commitment to offering our customers complete and unparalleled access to linear fiberoptic technology," Gertel concluded.

"There have been several recent announcements by major long distance carriers of plans to utilize CATV networks to provide local telephony. It is our belief that these plans will continue to create a strong demand in the market for our hybrid fiber coax products," said Kevin Kalkhoven, Chairman and CEO of Uniphase Corporation

This new family of transmitters, as well as other Uniphase products are on display at the Optical Fiber Communications Conference (OFC) at the San Diego Convention Center, February 23-25, 1999, in booth number 617.
