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
* Peak output power Pf = 10 mW MIN. * Available for DWDM wavelengths based on ITU-T recommendations (100 GHz grid, please refer to the ORDERING INFORMATION) * Internal thermo-electric cooler and isolator * Hermetically sealed 14-pin butterfly package * Single mode fiber pigtail * Wide operation temperature range
