Optical fibre cables - Generic specification. Basic optical cable test procedures. Mechanical tests methods. Galloping, Method E26

This document establishes a standardized framework for evaluating the mechanical resilience of optical fibre cables, specifically addressing performance under galloping conditions. The procedure focuses on testing methods designed to simulate dynamic loads induced by wind and ice accumulation on suspended cable spans. These tests are essential for verifying the structural integrity of optical cables in overhead transmission systems where environmental forces can cause significant movement. The guidelines outline specific experimental setups, loading parameters, and measurement techniques to assess how cables respond to oscillatory motion. By defining uniform test conditions, the document ensures that manufacturers and testing laboratories can generate comparable data regarding cable durability. The methodology covers various aspects of mechanical stress analysis, providing a systematic approach to identify potential failure modes associated with large-amplitude oscillations. Adherence to these procedures supports the qualification of optical cable products for deployment in regions susceptible to adverse weather phenomena. The standard serves as a technical reference for engineering assessments, enabling consistent evaluation of product performance without requiring subjective interpretation of test outcomes.
