GEZHI PHOTONICS Coarse Wavelength Division Multiplexing units are a flexible plug-and-play network solution that allows network operators to cost effectively implement point to point or ring based WDM optical networks.
Our CWDM Mux Demux are perfectly suited to transport PDH, SDH/SONET, ETHERNET services over WWDM, CWDM and DWDM in optical metro edge and access networks. Front panel Connectors, located on the front of the CWDM Mux Demux modules, are labeled and use the same color-coding that is used to indicate the wavelength of the individual CWDM transceivers. The connectors at the end of CWDM transceivers are similarly color-coded, which simplifies the process of connecting a CWDM transceiver to its associated device port.

GEZHI Photonics quality assurance by using high-quality CWDM Multiplexers. Our components fulfill or exceed standard market specifications for optical components. It may still not be entirely obvious how different parameters like isolation are more closely defined. The following diagram illustrates the most important parameters, following the "red box model", in accordance with ITU. The channel, including its bandwidth and isolation as defined by the component specifications, delineates a box. The measured transmission spectrum of each channel has to be above the box. Under no circumstances can it interfere with any neighboring box (channel). Therefore, isolation and insertion losses have to be maintained within the borders set out by the defined center wavelengths and bandwidth.
This GEZHI CWDM multiplexer is awesome! Super high isolation, runs super stable, and it arrived in just a few work days as promised. Total win for my WDM network!
