DESCRIPTION
NEC's NX7312UA is a 1310 nm Multiple Quantum Well (MQW)
structured Fabry-Perot (FP) laser diode TOSA (transmitter
optical subassembly) with InGaAs monitor PIN-PD in a recep-
tacle type package designed for SFF/SFP transceiver with LC
duplex receptacle. This device is ideal for Synchronous Digital
Hierarchy (SDH) systems, short haul STM-1 (S-S.1)and short
haul STM-4 (S-4.1), ITU-T recommendations, and SONET
OC-3(IR) and OC-12(IR).
ELECTRO-OPTICAL CHARACTERISTICS (TC = -40 to +85°C, unless otherwise specified)
