PIN Receiver Module
for 2.5 Gb/s
PGR 203 01
Description
Fiber optic receiver front-end module for STM-16 and OC-48 applications.
The module includes an InGaAs PIN Photo Diode, with a low noise GaAs
MMIC preamplifier in a 14 pin butterfly package. 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.
