Opnext to Preview Compact Modules for DWDM Networks at ECOC 2005.

EATONTOWN, N.J. -- Opnext, Inc., a global leader in high-performance optical components, will demonstrate the internetworking of various Opnext products at ECOC 2005 (European Conference and Exhibition on Optical Communication) in Glasgow, Scotland, September 26-28, 2005.

The internetworking demonstration showcases multiple DWDM channels at different data rates being transmitted over a span of fiber. The demonstration emulates a metropolitan DWDM network architecture where different data rates are being transmitted on different channels over a common span of fiber. The 10G DWDM channel will be driven by the Opnext full channel tunable 300 pin transponder, TRV709A. The 2.5G DWDM channel will be driven by the Opnext 100GHz spaced DWDM SFP, TRF7986. Additionally, an S64.2 XFP, TRF7050, will serve as the 10G data source for the 10G DWDM channel.

Opnext will also feature the following in its booth, #209 during ECOC:

--Opnext X-Modules, will show the broad range of Opnext's X-modules that support 10GbE network architectures. Products on display include Opnext's X2s 10GBASE-CX4 TRTC010, 10GBASE-SR TRT2000, 10GBASE-LR TRT5021, X2 10GBASE-ER TRT7051, XFP 10GBASE-LR TRF5010 and LX4 in both X2 and XENPAK form factors.

--Opnext 40 Gbit/s 300-pin transceiver, offers low power consumption of 20W typically, allowing less strain for broader telecom and datacom applications. The product, which offers a high level of integration, minimizing management complexity as well as costs, by reducing the number of ports through its 40 Gbit/s interface.

--Opnext's SFP portfolio, comprising more than fifty products and covering all standard bit rates and protocols, from GbE and F-C, to 155Mbit/s, 622Mbit/s and 2.5Gbit/s for SONET, SDH and ATM applications. The distances supported range from very short reach multimode applications, for the GbE and F-C protocols, all the way up to 80km and beyond for the SONET, SDH and ATM protocols. The Opnext pluggable designs have been optimized for cost and performance, operation across extended temperature ranges and can provide advanced real-time performance monitoring capabilities.

At ECOC 2005, Opnext will also showcase industry-leading, MSA compliant products and technology developments, which focus on three key areas of component design - lower cost, common footprint, higher quality and best in class performance. These products are based on Opnext's core optics, universal optical subassembly platform and augmented by Opnext's demonstrated expertise in building leading-edge 10G/bit devices and modules.

Opnext's expertise in communications is based upon a history of leading technical research. Opnext funds research in next-generation technologies for fiber optics communications. At ECOC, Opnext researchers will present updates to ongoing research on high-speed optoelectronics for communications.

--A 1310-nm InGaAlAs Short-Cavity DBR laser for 100 degrees C, 10-Gbit/s Operations with a 14-mApp Current Drive

A novel method to determine the unity gain responsivity of high-speed avalanche photodiode was proposed. It helps clarifying our APDs with thin InAlAs multiplication layer has achieved GB product over 172 GHz.

--43-Gbit/s Operation of 1.55 um Electro-Absorption Modulator Integrated DFB Laser Modules for 2-km Transmission

K Naoe, N Sasada, Y Sakuma, K Motoda, T Kato, M Akashi, M Okayasu, K Uomi, Opnext Japan Inc., Japan, J Shimizu, T Kitatani, M Aoki, Hitachi Ltd., Japan

We successfully demonstrated 43-Gbit/s operation of 1.55 um electro-absorption modulator integrated DFB laser module for 2-km transmission for the first time. A clearly opened eye, 0.6 dB power penalty, and +2.1 dBm output power were obtained respectively.
