NEC's SUPERLATTICE APD MODULE WITH INTERNAL PREAMPLIFIER NR4270MU-CC FOR 10 Gb/s APPLICATIONS
FEATURES
* SUPERLATTICE AVALANCHE PHOTO DIODE * INTERNAL GaAs TRANSIMPEDANCE PREAMPLIFIER * RECEIVER FOR 10 Gb/s TRANSMISSION (STM-4, OC-192) * MINIMUM RECEIVER SENSITIVITY Pr = -24 dBm MAX * TRANSIMPEDANCE Zt = 60 dB MIN * 17-PIN MINI-BUTTERFLY PACKAGE WITH SINGLE MODE FIBER * AC COUPLED-DIFFERENTIAL OUTPUT * WITH SC-UPC CONNECTOR
DESCRIPTION
NEC'S NR4270MU-CC is a 10 Gb/s superlattice avalanche photo diode (APD) receiver in a 17-pin mini-butterfly package with an internal preamplifier. This module is ideal as a receiver for SONET OC-192 and Synchronous Digital Hierarchy (SDH) systems, STM-64, and ITU-T recommendations.
