Dense Wavelength Division Multiplexer (DWDM) multiplexes optical signals of different wavelengths onto a single optical fiber (multiplexing), or separates multiple optical channels multiplexed in a single optical fiber by wavelength (demultiplexing). The 100G or 200G channel spacing dense wavelength division multiplexer/demultiplexer uses mature multi-cavity dielectric films to achieve optical filtering, with good wavelength stability and sealed packaging process, high environmental stability. Used in optical fiber amplifiers, OADM and OTC functions of DWDM systems, and application of DEDM technology in power systems.
Standard: Supports full-duplex and half-duplex modes
Wavelength: Complies with ITU-T G.695 standard
