CEx WDM Module Coexistence Module Optical Multiplexer
The CEx WDM Module Coexistence Module Optical Multiplexer is A single WDM device used to combine current G-PON FTTH services with emerging XGS-PON and Next Generation NG-PON2 technologies. Additional provisioning wavelengths with the Coexistence Element include RF, Point to Point (PtP), and OTDR monitoring. With high-quality connectivity ensure superior performance, the lowest loss, and robust network reliability. GEZHI CEx WDM Module Coexistence Module Optical Multiplexer is used in NG-PON2 access networks, optical singal distribution and so on.
