Opnext Demonstrates Fully Interoperable Universal Transponder and DWDM XENPAK at ECOC 2004.

EATONTOWN, N.J. & STOCKHOLM, Sweden -- Opnext, Inc., a global leader in high-performance optical components, today announced a live interoperability demonstration of the highly integrated TRV709BBN tunable transponder, and the TRE7062EN XENPAK, an advanced XENPAK module for Ethernet over DWDM. Both modules are integral to Opnext's 10G metro DWDM Ethernet portfolio of products. The interoperability demonstration will be held in Opnext's booth, #137, during the European Conference on Optical Communications (ECOC) in Stockholm, Sweden, from September 6th to 8th 2004.

The Opnext TRV709BBN full C-band tunable transceiver is for use in metro and long haul DWDM applications. Offering minimum size impact, Opnext's TRV709BBN can be deployed by optical communications system makers in the datacom and telecom markets, providing superior optical and electrical performance. The transceiver's tunable laser is capable of tuning full C-band with wavelength spacing of 50GHz, and supports multiple rates from 9.95Gbit/s to 11.1 Gbit/s. It also features a zero-chirp LiNbO3 Mach-Zehnder modulator, high-sensitivity APD, along with mux/demux in a 300-pin MSA-compliant package measuring 3.5"x4.5"x0.53."

The TRE7062EN XENPAK can transmit data beyond 80km over the standard single-mode fiber, utilizing a cooled integrated laser modulator (ILM) transmitter and avalanche photodiode (APD) receiver. The wavelength stability is +/- 100pm, which enables 100GHz spacing DWDM operation. Seamless interoperability between these high-speed optical and electrical components is critical for system designs at 10.3 G/bit per second and beyond.

"As the convergence of telecom and datacom continues, this interoperability demonstration at the physical layer of a DWDM application is vitally important. It demonstrates that Ethernet solutions can extend into the metro and easily communicate at the physical layer with telecom DWDM solutions," said Ed Cornejo, director of product marketing for Opnext. "Opnext is continuing to merge the capabilities of our products and develop new applications using current technologies. Our customers are demanding flexibility in their network implementation, which we can now offer with both pluggability and tunability in the physical layer."

10Gbit/s Pluggable Modules Portfolio

Opnext's 300-pin transponder and XENPAK transceiver covers all applications, from legacy fiber to long reach (80km and WDM). The X2 MSA transponder has been adopted by major system vendors, and is designed for space-constrained applications, particularly in enterprise environments. Its main application is for legacy fiber and distances of up to 10km. However, it can also be used for very short reach applications for single-mode and legacy multimode fiber to long reach single mode fiber (80km and WDM). The X2 MSA transceiver has been adopted by major system vendors, and is designed for space-constrained applications, particularly in enterprise switch environments. Its application also covers legacy multimode fiber and distances of up to 40km and beyond. Opnext is a technology and market leader in the 10Gbit/s Ethernet transceivers, offering a complete portfolio which includes; 10GBASE-CX4, 10GBASE-SR, 10GBASE- LR, 10GBase-ER, 10GBASE-ZR, and 10GBASE-DWDM.

SFP Portfolio

Opnext's SFP portfolio covers all standard bit rates and protocols, from GbE and FC, to 155Mbit/s, 622Mbit/s and 2.5Gbit/s for SONET, SDH and ATM applications. The distances supported range from very short multimode fiber applications, for the GbE and FC protocols, all the way up to 80km and beyond for the single mode fiber SONET, SDH and GbE protocols. The transceiver designs have been optimized for cost and performance, can operate across extended temperature ranges, and provide advanced real-time performance monitoring capabilities.
