MILPITAS, Calif. -- JDSU (NASDAQ: JDSU) (TSX: JDU) today announced availability of its 8500 series 40 Gigabit per second (40G) coherent (DP-QPSK) transponder for a broad range of high-speed optical networking applications that includes key coherent processing technology from system-on-chip (SoC) supplier ClariPhy.

Coherent optical transmission increases both the reach and capacity of fiber networks, eliminating bulky and expensive optical dispersion compensation equipment while simplifying network management for network operators. This allows network operators to deploy flexible networks that can be scaled to 100G and beyond in a easy and cost effective way.

The JDSU 8500 series transponder integrates a wide range of optical components from JDSU, including an intradyne coherent receiver, tunable laser, and lithium niobate modulator. It also includes the latest mixed signal digital processing (MXSP) system-on-chip technology from ClariPhy. The new transponder increases fiber capacity by a factor of four (versus 10G) while achieving over 3,000 km of reach on uncompensated fiber links.

"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."
