• LOW THRESHOLD CURRENT

• WIDE OPERATING TEMPERATURE RANGE:

• InGaAs MONITOR PIN-PD

• SMALL PACKAGE

ø3.8 mm TOSA (Total length 13.0 mm MAX)

NEC's NX8310UA is a 1310 nm Multiple Quantum Well (MQW)

structured Distributed Feed-Back (DFB) laser diode TOSA

(transmitter optical subassembly) with InGaAs monitor PIN-

PD in a receptacle type package designed for SFF/SFP

transceivers with LC duplex receptacle. This device is ideal for

Synchronous Digital Hierarchy (SDH) systems, long haul

STM-4 (L-4.1), ITU-T recommendations, and SONET OC-12

(LR).
