Product Description

Insert type CWDM coarse wavelength division multiplexer


product description


CWDM is using optical multiplexers to re-use different wavelengths of light into a single fiber-transmitted signal. At the receiving end of the link, the mixed signal is decomposed into signal splits in the fiber by means of an optical demultiplexer. Different wavelengths are connected to the corresponding receiving device.




Low insertion loss

High isolation


Compact design

Good channel-to-channel consistency

Wide operating wavelength: 1270-1610nm

Wide working temperature: -20 ° C ~ 70 ° C

High reliability and stability


Application field


CWDM system

PON network

Cable chain
