Optical fibres - Part 2-20: Product specifications - Sectional specification for category A2 multimode Mechanical fibres (IEC 60793-2-20:2015)
This part of IEC 60793 is applicable to sub-categories 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 sub-categories 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
L'IEC 60793-2-20:2015 est applicable aux fibres optiques des sous-catégories A2a, A2b, et A2c. Ces fibres sont utilisées ou peuvent être intégrées dans des équipements pour la transmission de l'information et dans des câbles à fibres optiques (typiquement jusqu'à 2 km). Trois types d'exigences s'appliquent à ces fibres:
- les exigences générales, qui sont définies dans l'IEC 60793-2;
- des exigences spécifiques communes aux fibres multimodales de catégorie A2, couvertes par la présente norme, et qui sont données dans l'Article 3;
- des exigences particulières applicables à des sous-catégories particulières de fibres ou à des applications données, qui sont définies dans les spécifications de famille figurant en annexe. Cette troisième édition annule et remplace la deuxième édition parue en 2007. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- NAth a été remplacé par NAff;
- la longueur du spécimen d'essai et les détails de mesure spécifiés pour la mesure du diamètre du coeur et de NAff.
Mots clés: des équipements pour la transmission de l'information, des câbles à fibres optiques, fibres multimodales de catégorie A2

Sectional specification for category A2 multimode fibres
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.
