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.
The NX8563LA series is a 1550 nm InGaAsP multiple‑quantum‑well distributed feedback (DFB) laser diode module designed for directly modulated DWDM, metro and CATV applications. It features a hermetically sealed 14‑pin butterfly package with an internal thermoelectric cooler and isolator, and operates over a wide temperature range.
The datasheet lists detailed electro‑optical characteristics, absolute maximum ratings, ordering part numbers, mechanical dimensions, and EU RoHS compliance information. It also includes a wavelength table based on ITU‑T recommendations for DWDM channels.
