EATONTOWN, N.J. -- OpNext Inc., a global leader in high-performance optical networking components, today introduced a new family of 10Gbit/s SerDes transceivers with a nominal 80km reach, featuring OpNext's new and highly sensitive avalanche photodiode (APD (-26 dBm at end of life). The transceiver series will be used by OpNext's top tier customer base in applications including DWDM systems, metropolitan area networks (MANs) and IP switches and ATM routers. The integrated devices give system vendors the reach and bandwidth capacity they require, allowing them to improve the performance of their optical networking systems while reducing their costs. The SerDes transceivers come in two form factors; the TRV7081(3.5" x 4.5" x 0.53"/0.77") utilizes a CW DFB laser and Lithium Niobate Mach-Zehnder modulator to achieve a fiber output power of +4dBm. For applications requiring conformance to ITU L-64.2a and Telcordia LR2 link budgets, the smaller TRV7061(3" x 4" x 0.53"/0.77") contains the OpNext 1550nm integrated laser modulator (ILM) and complies with the 300-pin Multi-Source Agreement (MSA) specifications. Both transceivers utilize OpNext's new APD receivers with an integrated bias control circuit. "OpNext is known in the marketplace for its great technology in laser diode modules, based on 25 years of research and development," said Joe Calvitti, Application Marketing Manager, OpNext. "The sensitivity achieved with this APD will place us on the map for receivers, and marks a major technological breakthrough for Hitachi and OpNext. It reinforces our already formidable market presence in the 10Gb/sec arena which is the fastest growing segment of the market." OpNext Inc.
