10-Gigabit-capable symmetric passive optical network (XGS-PON); ITU-T G.9807.1 (06/2016) ITU-T - International Telecommunication Union/ITU Telcommunication Sector Recommendation ITU-T G.9807.1 describes a 10-Gigabit-capable symmetric passive optical network (XGS-PON) system in an optical access network for residential, business, mobile backhaul and other applications. This system operates over a point-to-multipoint optical access infrastructure at the nominal data rate of 10 Gbit/s both in the downstream and upstream direction. Recommendation ITU-T G.XGS-PON contains the common definitions, acronyms, abbreviations, conventions, General requirements, Physical Media Dependent layer requirements, and Transmission Convergence layer requirements of the XGS-PON system.
