(Main)Optical fibres - Part 2: Product specifications - General
Optical fibres - Part 2: Product specifications - General
Contains the general requirements for both multimode and single mode optical fibres. Sectional specifications for each of the four multimode categories: A1, A2, A3, and A4 contain requirements specific to each category. The requirements of this standard apply to all categories. Each sectional specification contains the requirements that are common to all family specifications that are within it. Tests or measurement methods are defined for each specific attribute. This sixth edition cancels and replaces the fifth edition published in 2003. This modification has been necessary because of the addition of new fibre categories to IEC 60793-2-40, IEC 60793-2-50 and IEC 60793-2-60.
Fibres optiques - Partie 2: Spécifications de produits - Généralités
Contient les spécifications générales applicables à la fois aux fibres optiques unimodales et multimodales. Les spécifications intermédiaires pour chacune des quatre catégories multimodales: A1, A2, A3 et A4 contiennent des prescriptions spécifiques à chaque catégorie. Chaque spécification intermédiaire contient les prescriptions qui sont communes à toutes les spécifications de famille qu'elle regroupe. Les essais ou les méthodes de mesure sont définis pour chaque attribut spécifié. Cette sixième édition annule et remplace la cinquième édition publiée en 2003. Cette modification a été rendue nécessaire du fait de l'ajout de nouvelles catégories de fibres aux CEI 60793-2-40, CEI 60793-2-50 et CEI 60793-2-60.

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 60793-2 has been prepared by subcommittee 86A: Fibres and
cables, of IEC technical committee 86: Fibre optics.
This sixth edition cancels and replaces the fifth edition published in 2003. This modification
has been necessary because of the addition of new fibre categories to IEC 60793-2-40, IEC
60793-2-50 and IEC 60793-2-60.

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 multimode categories: A1,
A2, A3, and A4 contain requirements specific to each category. A sectional specification for
all single-mode categories contains requirements common to all single-mode fibres. Within
each sectional specification, family specifications – found as normative annexes – contain
requirements for the applicable sub-categories. These sub-categories are distinguished on
the basis of different fibre types or applications.
The requirements of this standard apply to all categories. 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 standard – otherwise the test or measurement
method is outlined in the relevant sectional specification.
The following table defines the sectional specifications. The relevant family specifications are
defined within the sectional specifications as normative annexes (see Tables 2 and 3)
