Coarse Wavelength Division Multiplexers (CWDM Series)

The Coarse Wavelength Division Multiplexer series is designed and manufactured based on Telcordia standard. The devices use environmentally stable thin film filter and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation and excellent environmental stability. They can be used individually to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in CWDM systems.
