The DWDM MUX&DEMUX 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 signals in the optical fiber into signals of different wavelengths; DWDM has 100 GHz, 200 GHz channel spacing, It is suitable for long-distance, large-capacity trunk network, or ultra-large capacity MAN core nodes, It is widely used in telecommunications 5G, MAN, backbone networks, data centers, etc.
