IEC 60793-2:2011

Optical fibres - Part 2: Product specifications - General

IEC 60793-2:2011 contains the general specifications for both multimode and single-mode optical fibres. Sectional specifications for each of the four categories multimode class: A1, A2, A3, and A4 contain requirements specific to each category. Sectional specifications for each of the two single-mode classes, B and C, 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 standard apply to all classes. This seventh edition cancels and replaces the sixth edition published in 2007. This modification has been necessary because of the addition of new fibre categories to IEC 60793-2-10 and IEC 60793-2-50.
This publication is to be read in conjunction with IEC 60793-1 series.

Fibres optiques - Partie 2: Spécifications de produits - Généralités

La CEI 60793-2:2011 contient les spécifications générales applicables à la fois aux fibres optiques unimodales et multimodales. Les spécifications intermédiaires pour chacune des catégories des quatre classes multimodales: A1, A2, A3 et A4 contiennent les exigences spécifiques à chaque catégorie. Les spécifications intermédiaires pour chacune des deux classes unimodales, B et C, contiennent les exigences communes à chaque classe. Chaque spécification intermédiaire inclut des spécifications de famille (dans les annexes normatives) qui contiennent des exigences pour la catégorie ou les sous-catégories applicables. La distinction entre ces différentes sous-catégories se fonde sur les différents types de fibres ou les différentes applications. Les exigences de la présente norme s'appliquent à toutes les classes. Cette septième édition annule et remplace la sixième édition publiée en 2007. Cette modification a été rendue nécessaire par l'ajout de nouvelles catégories de fibres dans la CEI 60793-2-10 et la CEI 60793-2-50.
Cette publication doit être lue conjointement avec la série CEI 60793-1.

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 seventh edition cancels and replaces the sixth edition published in 2007. This
modification has been necessary because of the addition of new fibre categories to
IEC 60793-2-10 and IEC 60793-2-50.

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 multimode class: A1, A2, A3, and A4
contain requirements specific to each category.
Sectional specifications for each of the two single-mode classes, B and C, 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 standard 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 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 to 5).
Annexes A and B summarize the existing fibre specifications.
