GENEVA -- Opnext, Inc. (NASDAQ: OPXT), a leader in high speed optical communications technology and a pioneer in 100Gbps coherent since first demonstrating its technology over North American and European networks more than 18 months ago, today introduced its 100Gbps DWDM (Dense Wavelength Division Multiplexing) MSA transponder module. Opnext’s MSA module, the OTM-100, is based on the latest second generation coherent technology and offers performance, power, size and cost advantages over first generation technologies and other alternatives in a 5” x 7” industry standard module.

The OTM-100 module is a fully-integrated, 100Gbps optical transponder that enables network equipment vendors to build 100Gbps metro, regional, long haul, ultra long haul and submarine transport solutions. The 100G Digital Coherent Signal Processing LSI (DSP-LSI) in the digital signal processor is made by NTT Electronics Corporation and is the product of the “R&D on High Speed Optical Transport System Technologies” project which was supported by the Ministry of Internal Affairs and Communications of Japan. Using Soft Decision Forward Error Correction (SD-FEC), the OTM-100 module improves reach, minimizing or eliminating the need for regeneration points, simplifies network deployment rules and reduces operating costs.

“Opnext has been leading the development of 100Gbps technology, including defining the ecosystem of the supply chain, for the past four years,” said Mike Chan, President of the Opnext subsystems business unit and Opnext’s Executive Vice President, Business Development & Marketing. “Our strength is in leveraging our engineering knowhow to put key technologies like coherent to work to deliver best-in-class performance.”

In a separate release:GENEVA -- Opnext, Inc. (NASDAQ: OPXT), a global leader in high speed optical communications technology, today announced the introduction and availability of its integrated tunable XFP (TXFP) transceiver during ECOC 2011, the European Conference and Exposition (ECOC) in Geneva, Switzerland, September 19-22. Opnext will demonstrate its tunable XFP transceiver at ECOC 2011, highlighting automatic wavelength tuning designed to deliver stable wavelength control while supporting a wavelength range of 1529 to 1567 nm.

The Opnext tunable XFP pluggable transceiver, developed in collaboration with Hitachi's Central Research Laboratory (CRL), is a hybrid design that combines the tunable laser and InP-MZ (Mach Zehnder) chips to offer superior optical shutter functionality. The tunable XFP transceiver delivers system performance to address mode-hopping for optimized wavelength stability in a variety of DWDM applications. In addition, the tunable XFP design can flexibly support negative chirp or zero-chirp DWDM applications to replace DWDM-XFP or 300-pin tunable transponders.

"Opnext's tunable XFP transceiver has been designed to provide our customers with wavelength control and reliability in a smaller form factor where high port density is valuable," said Tadayuki Kanno, President of Opnext's modules business unit. "Using our own, in-house designed compact tunable TOSA, we're bringing a TXFP module to market that can support the growing demand for tunable DWDM technologies."
