ITU-T G.986 PDF

This Recommendation describes 1 Gbit/s point-to-point Ethernet based optical access system for the optical access services including Optical Distribution Network (ODN) specification, physical layer specification and Operation, Administration and Maintenance (OAM) specification.

For an effective use of optical fibres cited in [ITU-T G.985], this Recommendation specifies only a single fibre bi-directional transmission system, dual-fibre systems being out of the scope of this Recommendation.

This Recommendation describes the case of a single domain managed ONT and related OLT requirements. The case of a dual domain managed ONT and related OLT requirements are for future study.
