DESCRIPTION
NEC's NX8564/8565/8566LE Series is an Electro-Absorption
(EA) modulator integrated, 1550 nm Multiple Quantum Well
(MQW) structured Distributed Feed-Back (DFB) laser diode.
The module is capable of 2.5 Gb/s applications of over 360
km, 600 km, 240 km ultralong-reach and available for Dense
Wavelength Division Multiplexing (DWDM) wavelengths
based on ITU-T recommendations, enabling a wide range of
applications.
