BASED ON Telcordia Reliability GR-468-CORE
DESCRIPTION
NEC's NX7315UA is a 1310 nm Multiple Quantum Well
(MQW) structured Fabry-Perot (FP) laser diode transmitter
optical subassembly (TOSA) with InGaAs monitor PIN-PD in
a receptacle type package designed for LC type SFF/SFP
transceiver modules. These devices are ideal for Synchronous
Digital Hierarchy (SDH) systems, STM-16 Intraof鏗乧e I-16 ITU-T
recommendations, and SONET OC-48(SR).
