CWDM is a technology that adds capacity to network by using the optical spectrum between 1270-1610nm, and it can realize up to 18 channels with wavelengths with a channel spacing of 20nm. Featuring in the wider frequency band, large wavelength interval, CWDM is mainly used for short-distance transmission.

Also, CWDM system is a flexible solution that allows multi-service like data, storage, voice or video to be transmitted on different wavelength channels over one single fiber. We provide an efficient and cost-effective way to transport those signals while reducing network complexity, simplifying operations and achieving better signal transmission, which is suitable for various installation environments.
