BS EN IEC 60794-1-209:2024

1 Scope This part of IEC 60794‑1 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 cable aging performance by high temperature exposure and temperature cycling in order to simulate lifetime behaviour of the attenuation of cables, or physical attributes. See IEC 60794‑1‑2 for a reference guide to test methods of all types and for general requirements and definitions.
