Sensors-Demeter Components Group Introduces 2.5 Gb/s and 10 Gb/s InGaAs Avalanche Photodiodes
Princeton, NJ, December 3, 2001 - 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 has achieved high yields for its APDs by using proprietary processing techniques coupled with improvements in epitaxial growth. Equally as important, the reliability of Sensors Unlimited s APDs is comparable to PIN diodes (< 1 FIT). The APDs are available on a submount or in a TO-46 can. The TO-46 packaged versions are sold with an integrated transimpedance amplifier for 2.5 Gb/s and 10 Gb/s data rates. With low inherent dark current and low-noise multiplication, these APDs increase the link budget of a fiber link between 6 and 8dB over their pin/preamp counterparts, allowing the extra link budget to be used for WDM and switching. The higher sensitivity in an APD receiver also has a clear economic advantage by reducing the cost of optical amplification by thousands of dollars.
In addition to APDs, Sensors-Demeter Components Group also offers InGaAs Linear and Area Photodiode Arrays, APD & PIN Receivers, Multi-Channel Power Monitors, NIR Imaging Cameras, DFB and FP Lasers, Active Bi-Di s, and Laser Combiners. All of these components will be leveraged to build new optical subsystems incorporating innovations arising from the integration of InGaAs and laser technologies in areas such as CWDM, DWDM, SONET/SDH, MANs, Transceivers, Transponders, Add/Drop Multiplexers, MEMS Switch Controls, EDFA Gain Monitoring, as well as Laser Beam Profiling, Free Space Communications, Semiconductor Inspection, LADAR, LIDAR and Spectroscopy. As one of the leading suppliers to the merchant market, Sensors-Demeter will enable transponder manufacturers to radically improve transceiver designs by incorporating its smaller, highly sensitive, reliable, high-speed components.
