DESCRIPTION

NEC's NX8567SA Series is an Electro-Absorption (EA) modu-

lator and wavelength monitor integrated, 1 550 nm Multiple

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

laser diode module. The module is capable of 2.5 Gb/s ap-

plications of over 240 km, 360 km, 600 km ultralong-reach and

available for Dense Wavelength Division Multiplexing (DWDM)

wavelengths based on ITU-T recommendations, enabling a

wide range of applications
