Scope

Recommendation ITU-T G.798 specifies both the components and the methodology that should be used in order to specify optical transport network functionality of network elements; it does not specify individual optical transport network equipment as such. The components in this revision support ODU and client signal and server bit rates up to 100 Gbit/s. This includes support of mapping and demapping of a multitude of client signals into carrier signals of various bit rates from STM1 as SDH transport rate and 1GE for data client rate up to the transport of 100 Gbit/s Ethernet LAN signal rate.
