CWDM Diode Laser Module

0.0/5 rating (0 votes)

Description

The CWDM diode laser module is comprised of an uncooled quantum well DFB laser chip,built-in InGaAs monitor photodiode,4-pin coaxial pigtail type or plug-in type package,single-mode fiber coupling device,SC/APC or FC/APC optical connector,and built-in optical isolator.Its light source covers a wide wavelength range from 1270nm to 1610nm,totaling 18 wavelengths.Other typical values for the CWDM diode laser module are ±3nm for the spectral range, spectral bandwidth less than 0.2nm, maximum operating current 35MA,and output power range from 1MW to 3MW.This series of product is most commonly used in the WDM light source and communication systems,CWDM analog communication systems,CATV return-path transmission systems,and other analog transmission systems.
