Agere and Yafo Networks collaborate on high-speed adaptive receiver technology

June 4, 2002--Agere Systems and Yafo Networks today announced a partnership to jointly develop integrated adaptive receiver technology for high-speed optical transmissions.

Agere Systems and Yafo Networks today announced a partnership to jointly develop integrated adaptive receiver technology for high-speed optical transmissions. Announced at Supercomm 2002, this device will offer superior receiver performance and low distortion at 40-Gbits/sec, say company representatives, giving systems manufacturers the ability to develop next-generation optical networks by eliminating one of the most limiting impairments in high data-rate systems.

Per the agreement, Yafo and Agere will develop 40-Gbit/sec receivers that incorporate polarization mode dispersion (PMD) compensation and other features inside a compact, integrated module. This agreement spans product definition and development of integrated receiver modules, combining Yafo's PMD compensation technology with Agere's expertise in 40-Gbit/s receiver design and other optical component technologies.

"This strategic partnership brings together two leaders in high-speed optical networks to develop the critical technologies needed to make 40-Gigabit networks a reality," contends Mark Granahan, vice president of Agere's optical access and transport division.

"We are thrilled to be working with Agere, one of the world's most highly-respected technology companies," adds Henry Yaffe, chief technology officer at Yafo Networks. "By leveraging our leading-edge innovations in PMD compensation and Agere's wide range of optical and electronic technologies, we can deliver great value to our mutual customers."

A receiver that integrates PMD compensation can reduce these pulse distortions at 40- Gbits/sec by converting any incoming polarization state back to the intended polarization during optical transmission. This adaptive receiver module would be intended for use in long-haul and ultra-long-haul applications. General availability of the adaptive receiver is expected in early 2003.
