Aerospace series - Fibres and cables, optical, aircraft use - Test methods -Part 801: Fibre movement under compression

This document specifies a method of measuring the semi loose effect of a semi loose cable.
Pull proof optical contacts are used. The optical contact (ferrule) is longitudinally moving to preserve the optical performance even when cables are pulled.
Consequently, the buffered fibre moves beneath the strength members (called semi loose effect).
This document describes a test methodology to assess the quality of the cable when contact is pulled or pushed.

Série aérospatiale - Fibres et câbles optiques à usage aéronautique - Méthodes d'essais - Partie 801 : Déplacement de la fibre sous compression

Le présent document spécifie une méthode de mesure de l’effet semi-lâche d’un câble semi-libre.
Des contacts optiques résistant à la traction sont utilisés. Le contact optique (ferrule) se déplace longitudinalement pour préserver les performances optiques même lorsque les câbles sont étirés.
En conséquence, la fibre gainée se déplace sous l'armature de renfort (ce qui est appelé « effet semi-libre »).
Le présent document décrit une méthodologie d’essai pour évaluer la qualité du câble lorsque le contact est étiré ou contracté.
