Eudyna and Fujitsu Develop Ultra Small, Low Power 2.5Gbps DWDM Transceiver

Eudyna Devices USA Inc.,Fujitsu Limited

San Jose, CA, USA and Tokyo, Japan, May 10, 2004

Eudyna Devices USA Inc. (EUDU), a leading supplier of optical components, and Fujitsu Limited, a leading provider of customer-focused IT and communications solutions for the global marketplace, today announced that they have started sampling DWDM 2.5 Gigabit small form-factor pluggable transceivers (SFP) to optical network equipment manufacturers. Eudyna Devices and Fujitsu have jointly developed the transceivers, which utilize Fujitsu's high level module development technology, Eudyna's high performance low power cooled Laser in a small TOSA package enabling SFP modules to support DWDM function, and Eudyna's high performance Avalanche Photodiode receiver in a compact ROSA package.

This ultra small, low power 2.5Gbps DWDM transceiver complies with SFP Multi-Source Agreement (MSA), which allows communication equipment manufacturers to design high port-density DWDM 2.5Gbps optical line cards at lower costs. In addition, the hot pluggable feature enables OEMs to reduce manufacturing cost and inventory and allows optical port upgrades and flexibility at the customers' premise at any point in time.

The DWDM SFP transceiver is capable of over 200km transmission that covers full C-band ITU-T grid at 100GHz spacing, operating between 0°C and 70°C with typical 1W power consumption, and it incorporates diagnostic monitoring function defined by the SFF-8472 standard.

The DWDM SFP transceiver is a part of Eudyna and Fujitsu's SFP transceiver family, which is already being supplied to customers supporting OC-48 SR-1 to LR-2 and CWDM. By integrating the transceiver into the SFP family, the two companies can now offer a total 2.5Gbps optical interface solution with one SFP package.

Eudyna's products include devices for fiber optic digital telecommunications applications in the 622 Mbs - 40 Gb/s range (laser diodes, receiver modules, GaAs IC's, LN modulators, XFPs, SFPs, and 300 pin MSA transponders*), and analog lasers for CATV applications (broadcast and return path). Eudyna produces lasers at ITU grid wavelengths for DWDM systems. Eudyna's products also include microwave and millimeter wave RF devices for cellular, handset, broadcast and satellite communications. LN modulators and 300 pin MSA transponders are produced by Fujitsu Limited and distributed by Eudyna USA Inc.
