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;
