OPTICAL FIBRE CABLES –

Part 2-30: Indoor cables –
Family specification for optical fibre ribbon
cables for use in terminated cable assemblies

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.
International Standard IEC 60794-2-30 has been prepared by sub-committee 86A: Fibres and
cables, of IEC technical committee 86: Fibre optics.
This third edition cancels and replaces the second edition published in 2008. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) removal of Annex C;
b) reference to the most recent fibre standards;
c) reference to IEC 60794-1-21, IEC 60794-1-22, IEC 60794-1-23 and IEC 60794-1-24.

This standard is to be used in conjunction with IEC 60794-1-1, IEC 60794-1-2 and
IEC 60794-2.
The text of this International Standard is based on the following documents:
CDV Report on voting
86A/1704/CDV 86A/1808/RVC

Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
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 "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

OPTICAL FIBRE CABLES –

Part 2-30: Indoor cables –
Family specification for optical fibre ribbon
cables for use in terminated cable assemblies



1 Scope
This part of IEC 60794 is a family specification which covers indoor optical fibre ribbon cables
for use in terminated cable assemblies. The requirements of the sectional specification
IEC 60794-2 are applicable to cables covered by this document.
The requirements of this document are written to define flat ribbon cables. This document can
be applicable to other cable constructions. Parts of IEC 60794-3 which are applicable for
ribbon tests are the subject of IEC 60794-1-31.
Annex B contains requirements that supersede the normal requirements in case the cables
1
are intended to be used in installation governed by the MICE table of ISO 11801-3 [4] .
2 Normative references
The following documents are referred to in the text in such a way that some or all of their
content constitutes requirements of this document. For dated references, only the edition
cited applies. For undated references, the latest edition of the referenced document (including
any amendments) applies.

4 Construction
4.1 General
In addition to the constructional requirements in IEC 60794-2, the following considerations
apply to ribbon cables for use in terminated cable assemblies.
The cable shall be designed and manufactured for a predicted operating lifetime of at least
15 years. In this context, the attenuation of the installed cable at the operational wavelength(s)
shall not exceed values agreed between the customer and the supplier. The materials in the
cable shall not present a health hazard within its intended use.
There shall be no fibre splice in a delivery length unless otherwise agreed by the customer
and the supplier.
It shall be possible to identify each individual fibre throughout the length of the cable.
4.2 Optical fibres and primary coating
Category A1 multimode fibres which meet the requirements of IEC 60793-2-10 or categories
B1.1, B1.2, B1.3, B2, B4, B5 and B6 single-mode optical fibres which meet the requirements

of IEC 60793-2-50 shall be used. The linear coefficient of optical fibre attenuation and
attenuation point discontinuity may be affected by the cable manufacturing process. Maximum
values for these optical characteristics shall be agreed between the customer and the supplier.
