Description
Fiber optic receiver front-end module for STM-16 and OC-48 applications. The module includes an InGaAs Avalanche Photo Diode (APD), with a low noise GaAs MMIC preamplifier in a 14 pin butterfly package.The module is equipped with an internal thermistor. The single-mode fiber pigtail is terminated with a customer specified connector. The module operates between 1250 and 1620 nm. The electrical output is AC-coupled, single ended and inverted i.e., light on equals logic low.
