光纤电缆.第3-70部分:室外电缆.快速/多用途室外光纤电缆系列规范

[中文适用范围]： 本部分为IEC 60794系列标准中的家族规范，涵盖适用于严酷陆地快速/多次部署的室外光缆。这些具有增强机械性能、环境适应性和防护性能的电缆可用于任何需要快速或多次部署的场合（例如移动广播单元、紧急救援服务、战术地面部队、户外移动机器人、采矿机械、损坏链路的临时修复电缆等）。 [外文原描述]： IEC 60794-3-70:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60794-3-70:2021 covers outdoor optical fibre cables intended for rugged terrestrial rapid/multiple deployment. These cables, with enhanced mechanical, environmental and ingress performance can be used wherever a rapid or multiple deployment is relevant (e.g. mobile broadcast units, emergency rescue services, tactical ground-forces, outdoor motion-robotics, mining machinery, temporary repair cables for damaged links, etc.). This second edition cancels and replaces the first edition published in 2016. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - incorporation of the new classification system for optical fibre categories, sub-categories in IEC 60793-2-10; - incorporation of the new classification system for optical fibre categories, sub-categories and models in IEC 60793-2-50; - updating of cabled fibre performance categories in alignment with ISO/IEC 11801-1; - updating of bibliographical references.
