This document summarizes the key standards for Passive Optical Network (PON) technologies, including GPON, XG-PON1, NG-PON2, and XGS-PON. It provides information on the nominal line rates, split ratios, maximum distances, wavelength ranges, and service mappings supported by each standard. The standards were developed by the ITU-T to support the evolution of PON technologies and enable higher speeds, longer reach, and greater user bandwidth capacities over optical fiber networks.

Editor's Notes

- #5 The Full Service Access Network (FSAN) has outlined its vision for fibre access networks for the coming decade. FSAN is an industry forum that includes over 20 operators and 70 members overall. The group identifies service requirements and develops optical access technologies that are passed to the International Telecommunication Union (ITU) for standardisation. XGS-PON is a single-wavelength PON standard that supports two rates: a 10-gigabit symmetrical rate and the asymmetrical 10 gigabits downstream (to the user) and 2.5 gigabits upstream originally introduced by XG-PON. TWDM-PON uses four wavelengths to deliver up to 40 gigabits of symmetrical bandwidth and has an option for eight wavelengths overall. TWDM-PON also uses tuneable lasers enabling operators to move subscribers between wavelengths.
