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 60793-2 has been prepared by subcommittee 86A: Fibres and
cables, of IEC technical committee 86: Fibre optics.
This ninth edition cancels and replaces the eighth edition published in 2015. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) introduction of the revised fibre designations for most A1 sub-category fibres and all
class B single-mode fibres;
b) addition of the new fibre model (A1-OM5) defined for A1 category;
c) addition of class D polarization maintaining fibres.

This document is to be read in conjunction with those parts of the IEC 60793-1 series that
address individual measurements and tests for attributes of optical fibres.
The text of this International Standard is based on the following documents:
FDIS Report on voting
86A/1964/FDIS 86A/1974/RVD

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 the parts in 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 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.

Part 2: Product specifications –
General



1 Scope
This part of IEC 60793 contains the general specifications for both multimode and single-
mode optical fibres.
Sectional specifications for each of the four categories of multimode fibres: A1, A2, A3, and
A4 (part of the multimode fibre class A) contain requirements specific to each category.
Sectional specifications for each of the three single-mode fibre classes, B, C and D contain
requirements common to each class.
Each sectional specification includes family specifications (in normative annexes) that contain
requirements for the applicable category or sub-categories. These sub-categories are
distinguished on the basis of different fibre types or applications.
The requirements of this document apply to all classes.
Each sectional specification contains the requirements that are common to all the family
specifications that are within it. These common requirements are copied to the family
specification for ease of reference.
Tests or measurement methods are defined for each specified attribute. Where possible,
these definitions are by reference to an IEC International Standard (see IEC 60793-1 series) –
otherwise the test or measurement method is outlined in the relevant sectional specification.
Table 1 defines the sectional specifications. The relevant family specifications are defined
within the sectional specifications as normative annexes (see Tables 2 to 5).
Annexes A and B summarize the existing fibre specifications.
