PGR 603 10
Optical Receiver Module
STM-16 LH / OC-48 LR
The receiver module is intended for use at
SDH and SONET bit rates. The receiver
meets all present requirements in the ITU-
T (G.957) and Bellcore (GR-253-
CORE) recommendations. The receiver
consists of an InGaAs APD, silicon
bipolar IC preamplifier, and silicon IC´s.
A high level of integration is employed
which results in small size, low power
consumption and high reliability.
Alarm output for loss of signal is
provided according to SDH/SONET
requirements.
