Summary:
|
Recommendation ITU-T G.709/Y.1331 defines the requirements for the optical transport network (OTN) interface signals of the optical transport network, in terms of:
– OTN hierarchy
– functionality of the overhead in support of multi-wavelength optical networks
– frame structures
– bit rates
– formats for mapping client signals.
Edition 6.5 (Amendment 3) of this Recommendation adds mapping of 800GBASE-R clients, clarifications to the description of GMP, and a new fine-grained path layer and tributary slot structure.
