8CH CWDM Mux Demux Compact Coarse Wavelength Division Multiplexer
8CH CCWDM Module Compact Coarse Wavelength Division Multiplexer
Mini CCWDMs (Compact Coasrse Wavelength Division Multiplexers) are offered in a compact, space-saving design ideal for tray-mount applications. Mini CCWDMs are available with an upgrade port. It's new technology from GEZHI Photonics. Compare normal CWDM module, the size is more compactable.
and low inserion loss&High Isolation.
Coarse Wavelength Division Multiplexing (CWDM) networks need multiplexer/demultiplexer (MUX/DEMUX) modules to combine and split the multi-wavelength optical signals. These modules are generally called CWDM MUX/DEMUX. Coupled with highly reliable passive optics (e.g., CWDM SFP/SFP+ transceiver), CWDM MUX/DEMUX modlues let operators make full use of available fiber bandwidth in local loop and enterprise architectures. GEZHI Photonics provides a series of CWDM MUX/DEMUX modules with as more as 18 channels (20nm spaced) in simplex or duplex configurations
