CWDM (Coarse Wavelength Division Multiplexer) is a low-cost WDM transmission technology for the access layer of metropolitan area networks. In principle, CWDM uses an optical multiplexer to multiplex optical signals of different wavelengths onto a single optical fiber for transmission. At the receiving end of the link, an optical demultiplexer is used to decompose the mixed signals in the optical fiber into signals of different wavelengths, which are connected to corresponding receiving equipment; Used in optical transmission, metropolitan area networks, and WDM technology.
Standard: Supports full-duplex and half-duplex modes;
Wavelength: Complies with ITU-T G.695 standard.
