scope:

This Recommendation pertains to flexible access networks using optical fibre technology. It describes a network supporting multiple services with bandwidth requirements ranging from that of voice to data and video, running at an aggregate reference downstream rate of 40 Gbit/s.

This Recommendation specifies characteristics of the physical media dependent (PMD) layer of a passive optical network (PON) system based on time and wavelength division multiplexing (TWDM) and an optional point-to-point wavelength division multiplexing (PtP WDM) system that can be used in an overlay to TWDM with the capability of bidirectional data transmission between optical line termination (OLT) and optical network unit (ONU).

The optical access network (OAN) addressed by this Recommendation enables the network operator to provide a flexible upgrade to meet future customer requirements, in particular, in the area of the optical distribution network (ODN). The legacy ODN infrastructure is based on a point-to-multipoint tree and branch option using power splitter based technology (see [ITU-T G.989.1] for additional details). However, the use of wavelength splitters in the ODN is also allowed.

This edition includes updates from Amendment 1, Amendment 2 and relaxes certain parameter values related to OOB/OOC/IBXT.
