G.657 is an international standard12 developed by the Standardization Sector of the International Telecommunication Union (ITU-T) that specifies single-mode optical fiber (SMF) cable.
History
The G.657 Recommendation builds on a previous fiber optic specification in G.652.34
G.657 was first published in 2006. Revisions of the standard were since published in 2009, 2012, 2016, and 2024 (August).56
