SIST EN 61753-031-3:2015

Fibre optic interconnecting devices and passive components - Performance standard - Part 031-3: Non-connectorised single-mode 1xN and 2xN non-wavelength-selective branching devices for Category U - Uncontrolled environment (IEC 61753-031-3:2014)

This part of IEC 61753 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 1 × N and
2 × N non-wavelength-selective branching devices for use in an IEC category U 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. for normal reach
PON application).
The requirements also cover unbalanced, bidirectional, non-connectorized, single-mode, nonwavelength-
selective branching devices; however, the specifications of unbalanced branching
devices are limited to 1 × 2 and 2 × 2 devices because they are the most commonly used.

Dispositifs d'interconnexion et composants passifs à fibres optiques - Norme de performance - Partie 031-3: Dispositifs de couplage indépendants de la longueur d'onde 1xN et 2xN en unimodal, non-connectorisés, pour catégorie U - Environnement non contrôlé (IEC 61753-031-3:2014)

L'IEC 61753-031-3:2014 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) satisfasse afin d'être classé comme conforme à la présente norme. Ces exigences couvrent les dispositifs de couplage 1xN et 2xN en unimodal, non connectorisés, bidirectionnels symétriques destinés à être utilisés dans un environnement de catégorie U selon l'IEC (N correspond au nombre de ports de connexion), 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 par exemple 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 1 x 2 et 2 x 2 car ce sont eux qui sont les plus couramment utilisés. Cette deuxième édition de l'IEC 61753-031-3 annule et remplace la première édition parue en 2009 et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- domaine d'application mis à jour et étendu pour rendre compte de l'introduction de deux classes de performances d'affaiblissement et d'uniformité pour les NWBD symétriques à la place des technologies des dispositifs de couplage du marché;
- liste des références normatives mise à jour;
- introduction simplifiée aux deux types de bandes spectrales;
- Article 5, Exigences de performances, mis à jour et étendu pour rendre compte de l'introduction de deux classes de performances d'affaiblissement et d'uniformité pour les NWBD symétriques;
- simplification des essais pour exclure les essais de chaleur humide (état continu) et de chocs pour les exigences de performances;
- modification de l'Annexe A pour introduire les exigences calculées et minimales pour l'affaiblissement et l'uniformité;
- mise à jour de l'Annexe B pour rendre compte de la révision des exigences de performances.

Optični spojni elementi in pasivne komponente - Tehnični standard - 031-3. del: Enorodni 1xN in 2xN nevalovno dolžinski selektivni optični sklopniki brez konektorjev za kategorijo U - Nenadzorovano okolje (IEC 61753-031-3:2014)

Ta del standarda IEC 61753 zajema najmanjše začetne zahteve in stopnje zahtevnosti za preskuse in meritve, ki jih mora izpolnjevati valovnodolžinsko neodvisni selektivni razvejilni element (NWBD), da ustreza zahtevam tega standarda.
Zahteve zajemajo uravnotežene dvosmerne enorodne valovnodolžinsko neodvisne selektivne razvejilne elemente 1 × N in
2 × N brez konektorjev za uporabo v okolju kategorije IEC U
(N je število razvejilnih vrat), ki se še posebej uporabljajo za PON, vendar ne izključno.
Za uravnotežene nevalovno dolžinske selektivne optične sklopnike sta obravnavana dva kakovostna razreda slabljenja in enotnosti:
razred A (premium razred), ki izpolnjuje strožje zahteve (tj. PON
z razširjenim dosegom), in razred B (standardni razred) za standardno uporabo (tj. PON
z običajnim dosegom).
Zahteve zajemajo tudi neuravnotežene dvosmerne enorodne nevalovno dolžinske
selektivne optične sklopnike; vendar so specifikacije neuravnoteženih optičnih
sklopnikov omejene na naprave 1 × 2 in 2 × 2, ker se uporabljajo najpogosteje.

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 61753-031-3 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This second edition of IEC 61753-031-3 cancels and replaces the first edition published in
2009 and constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) 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;

---------------------- Page: 9 ----------------------

SIST EN 61753-031-3:2015
– 4 – IEC 61753-031-3:2014 © IEC 2014
b) an updated list of normative references;
c) a more simplified introduction to the two types of spectral bands;
d) Clause 5, Performance requirements, has been updated and extended to reflect the
introduction of two attenuation and uniformity performance classes for balanced NWBD;
e) simplified test items to exclude tests for damp heat (steady state) and impact for
performance requirements;
f) Annexe A has been changed to introduce the calculated and minimum requirements for
attenuation and uniformity;
g) Annex B has been updated to reflect revised performance requirements.
The text of this standard is based on the following documents:
FDIS Report on voting
86B/3792/FDIS 86B/3824/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
IEC 61753 consists of the following parts, under the general title Fibre optic interconnecting
devices and passive components – Performance standard.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

Part 031-3: Non-connectorized single-mode 1×N and 2×N
non-wavelength-selective branching devices for Category U –
Uncontrolled environment



1 Scope
This part of IEC 61753 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 1 × N and
2 × N non-wavelength-selective branching devices for use in an IEC category U 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. for 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 1 × 2 and 2 × 2 devices because they are the most commonly used.
