PRODUCT
Semiconductor Solutions for High Speed Communication and Fiber Optic Applications
The FOA11002A1 is the industry's lowest power consuming STM64/OC-192 Transimpedance Amplifier for SDH/SONET systems in Silicon Germanium technology. This new device is a key component for future high speed optical communication systems for regional, metropolitan and backbone transport data networks at the highest speeds up to 10.7 Gbit/s over one single fiber. It is a member of the complete 10 Gbit/s chipset in the Silicon Germanium technology.
