CWDM Mux&Demux

WDM is a communication technology that combines a series of optical signals with different wavelengths and transmits them along a single optical fiber. At the receiving end, the optical signals with different wavelengths are separated by some means. This technology is used in WDM. CWDM is one kind of WDM.
