16x GPON+XGS-PON+CATV (1550nm) CEx WDM Multiplexer 1U 19'' Rack

Connector :

Co-existence, Single Fiber, for GPON/XGS-PON and CATV, 16x CEx module, 1U 19'' Rack

Coexistence Element (CEx) is a single WDM device used to combine current G-PON FTTH services with emerging XGS-PON and Next Generation NG-PON2 technologies to coexist during the transmission from OLT to ONU. Additional provisioning wavelengths with the Coexistence Element include RF Video CATV, Point to Point (PtP), and OTDR monitoring. LightOptics manufactured CEx WDM module is compliant with Telcordia GR-1209 GR-1221 to ensure the durability, accuracy and unlimited functionality. Each Coexistence Element (CEx) GPON/XGS-PON module we offer is guaranteed factory new and tested before shipment, regarding quality and functionality.
