DESCRIPTION

NEC's NX8560SJ Series is an Electro-Absorption (EA) Modu-

lator and wavelength monitor intergraded, 1550 nm Multiple

Quantum Well (MQW) structured Distributed Feed-Back (DFB)

laser diode module. It is capable of transmitting up to 40 km

standard single mode Þber (dispersion: 800 ps/nm) for 10 Gb/s

applications with built in wavelength monitor.
