CWDM multiplexing & demultiplexing LGX module is a TFF based wavelength division multiplexing technology, with a variety of package sizes and wavelength options; it multiplexes optical signals of different wavelengths into a single Optical fiber is used for transmission. Demultiplexing is used at the receiving end to decompose the signal in the optical fiber into signals of different wavelengths.
