OPTICAL FIBRES –
Part 1-1: Measurement methods and test procedures –
General and guidance
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60793-1-1 has been prepared by subcommittee 86A: Fibres and
cables, of IEC technical committee 86: Fibre optics.
This third edition cancels and replaces the second edition published in 2002.
The main changes with regard to the previous edition concern:
– re-wording of Clause 8: Categories of optical fibres;
– removal of Clause 10: Cross-reference of former test designations to current documents
– removal of the bibliography.

A list of all parts of the IEC 60793 series, published under the general title Optical fibres, can
be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
INTRODUCTION
Publications in the IEC 60793-1 series concern measurement methods and test procedures as
they apply to optical fibres.
Within the same series, several different areas are grouped, as follows:
Parts 1-10 to 1-19: General
Parts 1-20 to 1-29: Measurement methods and test procedures for dimensions
Parts 1-30 to 1-39: Measurement methods and test procedures for mechanical
characteristics
Parts 1-40 to 1-49: Measurement methods and test procedures for transmission and
optical characteristics
Parts 1-50 to 1-59: Measurement methods and test procedures for environmental
characteristics.

OPTICAL FIBRES –
Part 1-1: Measurement methods and test procedures –
General and guidance
1 Scope and object
This part of IEC 60793 lists and gives guidance on the use of documents giving the uniform
requirements for measuring and testing optical fibres, thereby assisting in the inspection of
fibres and cables for commercial (mostly telecommunications) purposes.
The individual measurement and test methods are contained in the different parts of the
IEC 60793 series. They are identified as IEC 60793-1-X, where "X" is an assigned sub-part
number, indicating its affiliation to IEC 60793-1.
In general, measurements and tests methods apply to all class A multimode fibres and
Class B single-mode optical fibres covered by the IEC 60793-2 series, although there may be
exceptions. Clause 1 of each part of IEC 60793 contains the scope for each particular
attribute.
