G.651.1 is an international standard[1] developed by the Standardization Sector of the International Telecommunication Union (ITU-T) that specifies multi-mode optical fiber (MMF) cable.[2]

## History

[edit]

The G.651.1 Recommendation builds on a previous fiber optic specification in G.651.

G.651.1 was first published in 2007. Revisions of the standard were since published in 2008, and 2018 (November).[3]
