This part of IEC 60794 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.
See IEC 60794-1-2 for a reference guide to test methods of all types and for general
