JDSU offers 8500 series 40-Gbps coherent transponder

Lightwave Staff

JDSU (NASDAQ: JDSU and TSX: JDU) says its 8500 series 40-Gbps coherent DP-QPSK transponder is now available for sampling. The module leverages coherent processing technology from ClariPhy Communications, which supplied similar technology to Oclaro for its MI 5000XM 40G coherent modules (see “ClariPhy, Oclaro tout 40-Gbps coherent”).

The JDSU 8500 series transponder integrates several of the company’s own optical components, including an intradyne coherent receiver, tunable laser, and lithium niobate modulator. The module will support more than 3,000 km of reach on uncompensated fiber links, JDSU asserts.

“ClariPhy’s single-chip coherent technology and the team’s ability to support a fast-paced development enabled us to deliver our 8500 series transponders to customers who have been looking for a cost- and power-effective upgrade path to 40G coherent transmissions,” said Tom Fawcett, vice president of marketing for transmission modules at JDSU. “We strongly believe that the shipment of this product marks a turning point in the wide-scale deployment of 40G coherent transmission.”

“JDSU is increasing the adoption rate of 40G coherent transmissions by delivering a power and cost efficient transponder based on its vertical integration of key optical components,” said Nariman Yousefi, CEO and president of ClariPhy. “We are proud to support JDSU in this area with our leading-edge SoC solutions.”

JDSU will demonstrate the new transponder at booth #1403 during OFC/NFOEC in Los Angeles from March 6-8, 2012.
