scope:

This Recommendation specifies a set of flexible-bandwidth interoperable short-reach optical transport network (OTN) interfaces, the so called FlexO-x-RS-m interface group, over which an aggregate OTUCn (n ≥ 1) can be transferred using bonded FlexO short-reach interfaces as lower bandwidth elements.

The types of FlexO short-reach interfaces that can serve as FlexO-x-RS-m group members are covered by application codes which are at the time of publication 4I1-9D1F, 4L1-9C1F, C4S1-9D1F, 4L1-9D1F, C4S1-4D1F, 8R1-4D1F, 4I1-4D1F and 8I1-4D1F. These application codes are presented in [ITU-T G.695] and [ITU-T G.959.1].

The definition of a FlexO-x-RS interface group complements the existing B100G functions specified in [ITU-T G.709], such as OTUCn frame, ODUk/flex, with new functions such as physical interface bonding, forward error correction (FEC) coding, group management and OTUCn (de)mapping.

This FlexO-x-RS Recommendation complements [ITU-T G.709] and [ITU-T G.798] and provides specifications for new functions that are specific to the processing of FlexO-x-RS-m interface group. In addition, some introduction material for the addressed application is included.
