10-Gigabit Symmetrical Passive Optical Network

XGS-PON is a 10-Gigabit passive optical network standard (ITU-T G.9807.1) that delivers symmetrical speeds of up to 10 Gbit/s.

It uses distinct wavelengths for downstream (1577 nm) and upstream (1270 nm) transmission, employing Time Division Multiplexing (TDM) and Time Division Multiple Access (TDMA), respectively.

As the successor to GPON, it is not backward compatible due to their differing wavelengths. However, this distinction allows XGS-PON to coexist on the same fiber as GPON through wavelength division multiplexing (WDM).
