DESCRIPTION
NEC's NX7314UA is a 1310 nm Multiple Quantum Well (MQW)
structured Fabry-Perot (FP) laser diode transmitter optical
subassembly (TOSA) with InGaAs monitor in a receptacle type
package designed for LC type SFF/SFP transceiver modules.
This device is ideal for Synchronous Digital Hierarchy (SDH)
systems, STM-1 LONG HAUL L-1.1, ITU-T recommendations,
and SONET OC-3(LR).
