This standard describes a higher speed bidirectional point-to-point (HS-PtP) Ethernet-based optical access system for the optical access services including the optical distribution network (ODN) specification, the physical layer specification, services requirements and the operation, administration and maintenance (OAM) specification.
For an effective use of optical fibres cited in [ITU-T G.986], this Recommendation specifies only a single fibre bidirectional transmission system, also known as diplex working as defined in [ITU-T G.982]. Dual-fibre systems are out of the scope of this Recommendation. This Recommendation also specifies systems with line rate at 10 Gbit/s. Amendment 1 adds the 25 Gbit/s specification and Amendment 2 adds the 50 Gbit/s specification. Amendment 3 adds the 100 Gbit/s specification for optical path loss budget classes SL (0-10 dB), SU (5-15 dB) and BL (10-20 dB). In addition, this Recommendation describes the case of a single domain managed optical network unit (ONU) and related optical line termination (OLT) requirements. The case of a dual domain managed ONU and related OLT requirements are for future study. |
