DESCRIPTION
NEC's NX8563LA Series is a 1 550 nm Multiple Quantum
Well (MQW) structured Distributed Feed-Back (DFB) laser
diode module with Single Mode Fiber.
It is designed as directly modulation light source and
ideal for optical transmission systems. The device is
available for Dense Wavelength Division Multiplexing
(DWDM) wavelengths based on ITU-T recommendations,
enabling a wide range of applications.
