CWDM Mux And Demux Coarse Wavelength Division Multiplexer Module 1270~1610nm
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
CWDM Mux And Demux feature
Low Insertion Loss
More wavelength transmission , save fiber resource
High Isolation
High Reliability and Stability
CWDM Mux And Demux Application field
Telecom System / Wireless Network
CATV System
Broadband wavelength division system
