CWDM( coarse wavelength division multiplexer) mux demux module takes advantage of thin film coating and we provide full range of CWDM from 1270nm~1610nm,and which are equipped with non-flux bonding micro optics packaging.

The module is designed for CWDM optical transmission systems and supports wavelength multiplexing and demultiplexing applications in fiber optic communication networks.

Features:

• from 1260nm to 1620nm 
• Wide Operating Temperature 
• Good channel-to-channel uniformity 
• Wide Operating Wavelength: 
• Low Insertion Loss 
• High Isolation 
• Low PDL 
• Compact Design
