IEC 60794-1-104:2024 applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. This document defines test procedures to be used in establishing uniform requirements for impact performance. Throughout this document the wording “optical cable” includes optical fibre units, microduct fibre units, etc. See IEC 60794-1-2 for general requirements and definitions and for a complete reference guide to test methods of all types.
This document partially cancels and replaces IEC 60794-1-21:2015, which will be withdrawn. In the context of the revision of IEC 60794-1-21:2015, its contents were split into separate test methods. It includes an editorial revision, based on the new structure and numbering system for optical fibre cable test methods.
