Coarse Wavelength Division Multiplexer Module
(4 channel / 8channel)
Coarse WDM Module is expanding the bandwidth of Metro/Access Networks. The 4-channel and 8-channel CWDM modules are based on Coarse Wavelength Division Multiplexer devices. They can act as MUX/DEMUX with 20nm channel spacing. It has low insertion loss, low PDL, high isolation and good thermal stability.

Coarse Wavelength Division Multiplexer (CWDM)
Coarse Wavelength Division Multiplexer series are designed and manufactured to Telcordial standard. The devices use environmentally stable Thin Film Filters and advanced packaging technology to achieve wide pass band, 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.
