NX8563LB
1 550 nm InGaAsP MQW-DFB LASER DIODE MODULE
CW LIGHT SOURCE FOR DWDM APPLICATIONS
DESCRIPTION
The NX8563LB is a 1 550 nm Multiple Quantum Well (MQW) structured Distributed Feed-Back (DFB) laser diode
module with Polarization Maintain Fiber (PMF).
It is designed as Continuous Wave (CW) light source and ideal for optical transmission systems with external
modulators. The device is available for Dense Wavelength Division Multiplexing (DWDM) wavelengths based on
ITU-T recommendations, enabling a wide range of applications.
