DESCRIPTION
NEC's NX8560MC Series is an Electro-Absorption (EA) Modu-
lator integrated, 1550 nm Multiple Quantum Well (MQW)
structured Distributed Feed-Back (DFB) laser diode module
with an internal driver IC. It is capable of transmitting up to 40
km standard single mode fiber (dispersion: 800 ps/nm) for 10
Gb/s applications with built in wavelength monitor.
