Product Overview of CEx WDM Module
Passive Optical Networks WDM Module GPON XGS PON CEx Multiplexer
CEx Multiplxer
The Coexistence Element (CEx) of xWDM/xPON multiplexer is a single WDM device 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.Its compliant with ITU-T G.984.5.
GEZHI offers a flexible platform of Coexistence Element products to fit a specific PON deployment that is most cost-effective to your needs – Depending on your requirements each CEx can be fully complemented with all PON services or with only the services requested.
