GPON vs XG-PON vs XGS-PON, What's the Difference?
Sep 25 , 2025
Passive Optical Network (PON) is the core technology for fiber-optic broadband. Leveraging the advantages of "passivity" (no power supply required for the Optical Distribution Network/ODN), low cost, high reliability, and wide coverage (up to 20 km), it has become the mainstream of broadband networks. GPON, XG-PON, and XGS-PON represent three key phases in the evolution of PON technology, with cor...
