IEC 60794-3-70:2021作为IEC 60794-3-70:2021 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。 IEC 60794-3-70:2021涵盖了用于崎岖地面快速/多次部署的室外光缆。这些电缆具有增强的机械、环境和入口性能，可用于任何与快速或多次部署相关的地方（例如，移动广播单位、紧急救援服务、战术地面部队、户外运动机器人、采矿机械、损坏链路的临时修复电缆等）。）.这第二版取消并取代了2016年出版的第一版。它构成技术修订。 与上一版相比，此版本包括以下重大技术变更:-纳入IEC 60793-2-10中光纤类别、子类别的新分类系统； -在IEC 60793-2-50中纳入光纤类别、子类别和型号的新分类系统； -根据ISO/IEC 11801-1更新电缆光纤性能类别； -更新参考书目。

IEC 60794-3-70:2021 is available as IEC 60794-3-70:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the 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.
