OPTICAL FIBRE CABLES –
Part 3-70: Outdoor cables – Family specification for outdoor optical
fibre cables for rapid/multiple deployment
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 60794-3-70 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical
committee 86: Fibre optics. It is an International Standard.
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:
a) incorporation of the new classification system for optical fibre categories, sub-categories in
IEC 60793-2-10;
b) incorporation of the new classification system for optical fibre categories, sub-categories
and models in IEC 60793-2-50;
c) updating of cabled fibre performance categories in alignment with ISO/IEC 11801-1;
d) updating of bibliographical references.

Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in

described in greater detail at /standardsdev/publications.
This International Standard is to be used in conjunction with IEC 60794-1-1, IEC 60794-1-2 and
IEC 60794-3.
A list of all parts in the IEC 60794 series, published under the general title Optical fibre cables,
can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,

• amended.
OPTICAL FIBRE CABLES –
Part 3-70: Outdoor cables – Family specification for outdoor optical
fibre cables for rapid/multiple deployment
1 Scope
This part of IEC 60794 is a family specification that 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.).
