Optical fibres - Part 1-43: Measurement methods - Numerical aperture measurement (IEC 60793-1-43:2015)

This part of IEC 60794, which is a family specification, covers optical telecommunication
cables to be used in ducts or direct buried applications. The cable may also be used for
lashed aerial applications. Requirements of the sectional specification IEC 60794-3 for duct,
buried and aerial cables are applicable to cables covered by this standard.

Fibres optiques - Partie 1-43 : Méthodes de mesure et procédures d'essai - Mesure de l'ouverture numérique (IEC 60793-1-43:2015)

IEC 60793-1-43:2015 établit des exigences uniformes pour mesurer l'ouverture numérique d'une fibre optique, contribuant ainsi au contrôle des fibres et câbles dans des relations commerciales. L'ouverture numérique (NA, numerical aperture) d'une fibre multimodale des catégories A1, A2, A3 et A4 est un paramètre important qui décrit la capacité de la fibre à capter le rayonnement lumineux. Il est utilisé pour prévoir l'efficacité de l'injection, les pertes aux épissures et la tenue aux microcourbures et aux macrocourbures. L'ouverture numérique est définie en mesurant le diagramme en champ lointain (NAff). Dans certains cas, l'ouverture numérique théorique (NAth) est utilisée dans la documentation. Elle peut être déterminée en mesurant la différence entre l'indice de réfraction du cœur et celui de la gaine. Idéalement, il convient que ces deux méthodes donnent la même valeur. Cette deuxième édition annule et remplace la première édition parue en 2001, dont elle constitue une révision technique. La présente édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
– élargissement du domaine d'application pour inclure les catégories A1, A2, A3 et A4 de fibres multimodales;
– ajout de paramètres de mesure de la longueur des échantillons et de valeurs seuils spécifiques aux produits, aux variables actuelles des spécifications de produit;
– une nouvelle Annexe B, "Valeurs par défaut spécifiques à un produit pour la mesure de l'ouverture numérique";
– ajout d'une nouvelle Technique 4, destinée à la mesure de l'ouverture numérique des fibres A4d;
– une nouvelle Annexe A, "Mise en correspondance de mesures d'ouvertures numériques avec des longueurs différentes" qui présente une fonction de mise en correspondance destinée à établir une relation entre des mesures sur des échantillons plus courts et la longueur proposée pour obtenir Naff par la méthode d'essai de référence.
Mots clés: l'ouverture numérique d'une fibre optique, contrôle des fibres et câbles

OPTICAL FIBRE CABLES –

Part 3-10: Outdoor cables – Family specification for duct, directly buried
or lashed aerial optical telecommunication cables

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 relian
