PRINCETON, N.J. -- Sensors-Demeter Components Group announces 2.5 Gb/s and 10 Gb/s Indium Gallium Arsenide (InGaAs) Avalanche Photodiodes (APDs), which are used in OC48/STM-16 and OC192/STM-64 transponder/transceiver applications. Sensors Unlimited's APDs are used in transceivers to build CWDM-based metro access equipment that is complementary to existing DWDM core equipment, while being lower in cost, easier to provision, and simpler to operate. This enables Metropolitan Area Networks (MANs) to seamlessly connect high-speed Local Area Networks (LANs) and Wide Area Networks (WANs), effectively eliminating the 1Mb/s barrier found in existing copper cable. "Sensors Unlimited's APD receivers should have great appeal to LAN, SAN and metro access vendors who want to add WDM capability to their existing product suites," notes John Lively, director, Optical Components at RHK, Inc. "The increased receiver sensitivity of APDs provides several dB of additional link margin that can be used to reduce overall system cost. Many transceiver manufacturers should find this product attractive."Sensors Unlimited Inc., an innovative manufacturer of Indium Gallium Arsenide (InGaAs) optical components, and Demeter Technologies, the foremost manufacturer of advanced laser diodes and optical modules, have combined their sales and marketing efforts to create Sensors-Demeter Components Group. As a division of Finisar Corporation, (Nasdaq: FNSR), this group will specialize in products that advance the performance of high-speed fiber-optic communications through a broad array of products.
