Optical fibres - Part 2-20: Product specifications - Sectional specification for category A2 multimode fibres (IEC 60793-2-20:2007)

This part of IEC 60793-2 is applicable to optical fibres type A2a, A2b, and A2c. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables (typically up to 2 km).
Three types of requirements apply to these fibres:
– general requirements as defined in IEC 60793-2;
– specific requirements common to the category A2 multimodal fibres covered in this standard and which are given in Clause 3;
– particular requirements applicable to individual fibre types or specific applications, which are defined in the normative family specification annexes.

Fibres optiques - Partie 2-20: Spécifications de produits - Spécification intermédiaire pour les fibres multimodales de catégorie A2 (CEI 60793-2-20:2007)

Décrit des prescriptions spécifiques des fibres optiques de type A2a, A2b et A2c. Ces fibres sont utilisées dans des équipements pour la transmission de l'information et dans des câbles à fibres optiques (généralement jusqu'à 2 km). Pour les prescriptions générales, voir la CEI 60793-2. Les principaux changements par rapport à l'édition précédente sont: l'addition  d'exigences concernant la force de traction; la suppression des exigences concernant l'immersion dans l'eau; l'addition d'exigences environnementales.

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 60793-2-20 has been prepared by subcommittee 86A: Fibres and
cables, of IEC technical committee 86: Fibre optics.
This second edition cancels and replaces the first edition, published in 2002. It constitutes a
technical revision
