Fibre optic interconnecting devices and passive components - Performance standard - Part 031-6: Non-connectorized single-mode 1×N and 2×N non-wavelength-selective branching devices for Category O - Uncontrolled environment
IEC 61753-031-6:2014 contains the minimum initial tests and measurement requirements and severities which a non-wavelength selective branching device (NWBD) should satisfy in order to be categorized as meeting the requirements of this standard. The requirements cover balanced bidirectional non-connectorized single-mode 1xN and 2xN non-wavelength-selective branching devices for use in an IEC category O environment (N is the number of branching ports), especially but not exclusively used for PON application. For balanced NWBD, two attenuation and uniformity performance classes are considered:
- class A (premium class) which meets more restrictive requirements (i.e. for extended reach PON application) and
- class B (standard class) for standard application (i.e. normal reach PON application). The requirements also cover unbalanced bidirectional non-connectorized single-mode non-wavelength-selective branching devices, however the specifications of unbalanced branching devices are limited to 1x2 and 2x2 devices because they are the most commonly used. This second edition of IEC 61753-031-6 cancels and replaces the first edition published in 2008 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- deletion of the Introduction;
- an updated and extended scope to reflect an introduction of two attenuation and uniformity performance classes for balanced NWBD instead of branching device technologies on the market;
- an updated list of normative references;
- a more simplified introduction to the two types of spectral bands;
- Clause 5, Performance requirements, has been updated and extended to reflect the introduction of two attenuation and uniformity performance classes for balanced NWBD;
- simplified test items to exclude tests for damp heat (steady state) and impact for performance requirements;
- Annex A has been changed to introduce the calculated and minimum requirements for attenuation and uniformity. Keywords: non-wavelength selective branching device (NWBD), IEC category O environment
Dispositifs d'interconnexion et composants passifs fibroniques - Norme de performance - Partie 031-6: Dispositifs de couplage indépendants de la longueur d’onde 1 x N et 2 x N en unimodal non connectorisés pour la catégorie O - Environnement non contrôlé
IEC 61753-031-6:2014 contient les exigences et les sévérités initiales minimales d’essais et de mesures auxquelles il convient qu’un dispositif de couplage indépendant de la longueur d’onde (NWBD, non-wavelength selective branching device) satisfasse afin d’être classé comme satisfaisant aux exigences de la présente norme. Ces exigences couvrent les dispositifs de couplage indépendants de la longueur d’onde 1xN et 2xN en unimodal, non connectorisés, bidirectionnels symétriques destinés à être utilisés dans un environnement de catégorie O selon l’IEC (N correspond au nombre de ports de couplage), qui sont utilisés, en particulier, mais pas de manière exclusive, pour les applications PON. Dans le cas des NWBD symétriques, deux classes d’affaiblissement et d’uniformité sont prises en compte: la classe A (classe de première qualité) qui satisfait aux exigences les plus restrictives (à savoir pour les applications PON étendues) et la classe B (classe normale) pour les applications normales (à savoir les applications PON d’étendue normale). Ces exigences couvrent aussi les dispositifs de couplage indépendants de la longueur d’onde en unimodal, non connectorisés, bidirectionnels asymétriques, toutefois les spécifications des dispositifs de couplage asymétriques sont limitées aux dispositifs 1x2 et 2x2, car ce sont les plus couramment utilisés. Cette deuxième édition de l’IEC 61753-031-6 annule et remplace la première édition parue en 2008 et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
- la suppression de l’Introduction;
- un domaine d’application mis à jour et étendu pour refléter l’introduction de deux classes de performance d’affaiblissement et d’uniformité pour les NWBD symétriques à la place des technologies de dispositifs de couplage du marché;
- une liste mise à jour des références normatives;
- une introduction plus simple des deux types de bandes spectrales;
- l’Article 5, Exigences de performances, a été mis à jour et étendu pour refléter l’introduction de deux classes de performance d’affaiblissement et d’uniformité pour les NWBD symétriques;
- des éléments soumis à essai simplifiés pour exclure les essais de chaleur humide (essai continu) et d’impact pour les exigences de performance;
- l’Annexe A a été modifiée pour introduire les exigences calculées et minimales en matière d’affaiblissement et d’uniformité.

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
