18CH CWDM Mux Demux

Corephy 18CH low loss BIDI CWDM based on dielectric thin-film filter technology which designed for integration in low cost access and metro networks. It can multiplex up to 18 CWDM optical signal in a single optical fiber with only 3.5dB link insertion loss. It is package by 120*80*18mm ABS box with 900um loose tube, 2.0mm cable or 3.0mm cable, 1meter, all port with LC/UPC connector. The 18CH CWDM filter has high channel isolation and can be used in a bi-directional system. The module can be used as a multiplexer or de-multiplexer and uses a single slot in a frame or can be used, standalone, in an N-box.
