CEx WDM Module (Coexistence WDM?Module) is a wavelength coexistence device used for PON (Passive Optical Network) upgrades. It is designed to allow different generations of PON technologies, such as GPON, XGS-PON, and NG-PON2, to be transmitted simultaneously on the same optical. The PON Coexistence Element (CEx) module enables multiple services—including GPON, XG (S)-PON, NG-PON2, OTDR, and other current or future technologies—to operate simultaneously over a single fiber using wavelength multiplexing. It provides a smooth and cost-effective upgrade path to next-generation. Therefore, with the Optical Distribution Network (ODN) unchanged, xPON WDM (multiplexer) can be added at the Central Office (CO) to multiplex GPON and 10G GPON signals. This integration allows multiple wavelengths to transmit data over a single fiber, significantly enhancing efficiency. Current networks. There are 4 types of configuration which can be offered, please choose according to your project needs: WDMx, GPON + XGS-PON + NG-PON2, GPON + XGS-PON + NG-PON2 + RF-Video, GPON + XGS-PON + NG-PON2 + RF-Video + OTDR.
