IEC 60794-2-31:2019 is available as /2 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60794-2-31:2019 presents the detailed requirements specific to this type of cable to ensure compatibility with the series of International Standards ISO/IEC 11801, Information technology – Generic cabling for customer premises (Parts 1 to 6). The requirements of family specification IEC 60794-2-30 are applicable to cables covered by this document. The particular requirements detailed in Clause 4 define either a specific option in relation to the requirements of IEC 60794-2-30 or additional requirements. This third edition cancels and replaces the second edition published in 2012. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) incorporation of the OM5 cabled fibre performance category; b) incorporation of the OS1a cabled fibre performance category; c) cabled fibre performance categories OM1, OM2 and OS1 are no longer normative, and are retained for information.
