CWDM

The CWDM MUX&DEMUX ABS module is a wavelength division multiplexing technology based on TFF (thin film filter), which has a variety of package sizes and wavelength options; It Mux the optical signals of different wavelengths to a single optical fiber for transmission, and the receiving end uses the DEMUX to decompose
the sianals in the optical fiber into sianals of different wavelenaths: Because of the advantages of CWDM, such as wide band and low requirement for system equipment, it has occupied an important position in the access layer of MAN, and is widely used in telecommunications, enterprise network, campus network and other fields.
