PGR 203 14 APD Receiver Module for 2.5 Gb/s Key Features • Hermetic, 14 pin butterfly package with multisourced footprint • FC/PC, SC or ST connector • InGaAs APD with low noise GaAs MMIC preamplifier • AC-coupled, single-ended data output • Operates between 1250 nm and 1620 nm • 1.7 GHz typical bandwidth • -34 dBm typical sensitivity • -3 dBm typical overload Applications • SDH STM-16 LH • SONET OC-48 LR • Digital recievers to 2.5 Gb/s • Analog receivers to 1.7 GHz 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. 1 PGR 203 14 DATA FIBER PREAMP APD Figure 1.
