DESCRIPTION

The NX8511UD is a 1 550 nm Multiple Quantum Well (MQW) structured

Distributed Feed-Back (DFB) laser diode TOSA (transmitter optical sub-

assembly) with InGaAs monitor PIN-PD in a receptacle type package

designed for SFF/SFP transceiver with LC duplex receptacle.

This device is ideal for Synchronous Digital Hierarchy (SDH) system, long

haul STM-16 (L-16.2), ITU-T recommendations, and SONET OC-48 (LR-2).
