scope:

This Recommendation describes the general requirements of higher speed passive optical networks (HSP) that operate at speeds of over 10 Gbit/s per channel, for residential, business, mobile backhaul, and other applications. This Recommendation includes the principal deployment configurations, migration scenarios from legacy PON systems, and system requirements. This Recommendation also includes the service and operational requirements to provide for a robust and flexible optical access network supporting all access applications.

The HSP systems can meet the needs of a wide range of networks in diverse markets and is deployable in numerous applications in an efficient manner. As much as possible, this Recommendation maintains the characteristics from legacy PON systems: [b-ITU-T G.982], ITU T G.983.x, ITU-T G.984.x, ITU-T G.987.x, ITU-T G.989.x, and ITU-T G.9807.x series of Recommendations. This is to promote backward compatibility with existing optical distribution networks (ODN) that comply with those Recommendations and re-use established technical capabilities as much as possible. This Recommendation also describes smooth migration scenarios from legacy PON systems to HSP systems. Furthermore, HSP systems are expected to meet bandwidth growth and enable new revenue streams on legacy ODNs as well as supporting greenfield applications over new ODNs.
