IEC 60794-1-201: 2024 defines test procedures to be used in establishing uniform requirements for the environmental performance of: - optical fibre cables for use with telecommunication equipment and devices employing similar techniques; and - cables having a combination of both optical fibres and electrical conductors. Throughout this document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc. This document defines a test standard to determine the ability of a cable to withstand the effects of temperature cycling by observing changes in attenuation. See IEC 60794-1-2 for a reference guide to test methods of all types and for general requirements and definitions. This document partially replaces IEC 60794-1-22:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60794-1-22:2017: a) all references to the temperature sensing device have been removed and replaced with a note "for further study"; b) the conditioning procedure has been separated into Procedure 1 and Procedure 2 to avoid confusion; c) the ambient temperature test condition has been defined as per IEC 60794-1-2; d) the minimum soak time has been decreased for sample mass >16 kg in Table 1. L’IEC 60794-1-201:2024 definit les procedures d’essai a utiliser pour definir des exigences harmonisees pour les performances environnementales: - des cables a fibres optiques destines a etre utilises avec les equipements et dispositifs de telecommunications employant des techniques similaires; et - des cables combinant fibres optiques et conducteurs electriques. Dans le present document, le terme "cable optique" peut egalement englober les unites de fibres optiques, les unites de fibres en microconduit, etc. Le present document definit une norme d’essai pour determiner l’aptitude d’un cable a resister aux effets de cycles de temperature, en observant les variations de l’affaiblissement.
