Optical fibre cables - Part 1-107: Generic specification - Basic optical cable test procedures - Mechanical test methods - Torsion, method E7

Scope

IEC 60794-1-107:2025 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 used in establishing uniform requirements for torsion performance. Refer to IEC 60794-1-2 for a reference guide to test methods and for general requirements and definitions.

NOTE Throughout this document, the wording "optical cable" also includes optical fibre units, microduct fibre units, etc.

This first edition partially cancels and replaces IEC 60794-1-21:2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60794-1-21:2015:

a) Update of the typical test length according to the different types of cables;

b) Update of Figure 2 by loading weights to cable gripping fixture.
