DESCRIPTION
NEC's NX8560LJ Series are an Electro-Absorption (EA)
Modulator integrated, 1550 nm Multiple Quantum Well (MQW)
structured Distributed Feed-Back (DFB) laser diodes. It is ca-
pable of transmitting up to 40 km for 10 Gb/s applications by
using standard fiber dispersion 800 ps/nm and is available for
Dense Wavelength Multiplexing (DWDM) wavelength based
on ITU-T recommendations.
