IEC 60794-1-207 Ed. 1.0 b:2025

Full Description

IEC 60794-1-207:2025 describes test procedures to be used in establishing uniform
requirements for optical fibre cables for the environmental property: performance degradation
when exposed to nuclear radiation.
This document 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.
Method F7A evaluates performance degradation of optical fibre cable in environmental
background radiation; Method F7B evaluates performance degradation of optical fibre cable in
adverse nuclear environments.
NOTE Throughout the document, the wording "optical cable" can also include optical fibre units, microduct fibre
units, etc.
