Publication date:   Sep 18, 2024

Scope

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.
