Optical fibre cables - Part 1-129: Generic specification - Basic optical cable test procedures - Mechanical tests methods - Straight midspan access to optical elements, Method E29

Scope

IEC 60794-1-129:2025 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. The document defines test procedures used in establishing uniform requirements for mechanical performance-straight midspan access to optical elements. Throughout this document, the wording "optical cable" also includes optical fibre units, microduct fibre units, etc.

NOTE See IEC 60794‑1‑2 for a reference guide to test methods of all types and for general requirements and definitions.
