ITU-T L.316 PDF

This Recommendation specifies cable identification for the construction and maintenance of optical cable networks. Cable identification is performed to find or trace a target cable or route by optical fibre sensing techniques under deployed conditions characterized by the number of cables.

Optical fibre identification that is used to identify a particular fibre among many fibres is specified in [ITU-T L.314].

This Recommendation:

– describes functional requirements for cable identification performed on deployed optical fibre cable networks;

– gives a classification of and information on optical fibre sensing techniques;

– gives requirements for in-service cable identification without interfering with optical communication signals;

– describes procedures and system configurations for cable identification.
