Description
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 fiber.
It is a transitional technology product that enables coexistence between old and new networks during network upgrades, facilitating smooth upgrades and saving fiber resources.
