LASER DIODE
NX8563LA Series
1 550 nm InGaAsP MQW-DFB LASER DIODE MODULE
2.5 Gb/s DIRECTLY MODULATION LIGHT SOURCE FOR DWDM APPLICATIONS
DESCRIPTION
The 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.
FEATURES
