IEC 60794-1-1:2023

Overview

IEC 60794-1-1:2023 – Optical Fibre Cables – Part 1-1: Generic Specification – General is an international standard developed by the International Electrotechnical Commission (IEC). This standard specifies generic requirements for optical fibre cables, including cables for communication equipment, and cables that combine optical fibres with electrical conductors, such as optical ground wires (OPGW) and optical phase conductor cables (OPPC). Additionally, hybrid communication cables are specified in the IEC 62807 series.

The primary objective of IEC 60794-1-1:2023 is to establish uniform requirements for the design, construction, and performance characteristics of optical fibre cables. This includes specifications for geometrical, transmission, material, mechanical, environmental, climatic, and electrical properties of optical fibre cables and their elements. The 2023 edition is a technical revision, offering an improved, logical structure and expanded content to support consistent implementation worldwide.
