Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-4: Examinations and measurements - Attenuation
IEC 61300-3-4: 2022 describes the various methods available to measure the attenuation of optical components. It is not, however, applicable to random mate attenuation measurements as described in IEC 61300-3-34 and IEC 61300-3-45 nor for attenuation measurements of dense wavelength division multiplexing (DWDM) devices as described in IEC 61300-3-29. This fourth edition cancels and replaces the third edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) addition of Clause 3 containing terms, definitions and abbreviated terms;
b) addition of a new LSPM measurement method, insertion method (D);
c) addition of Annex A describing attenuation measurement of multicore fibre;
d) changed reference test method to insertion C and alternative test method to substitution or insertion D for power meter and type 4 DUT.
The contents of the corrigendum of June 2023 have been included in this copy.
Dispositifs d'interconnexion et composants passifs fibroniques - Procédures fondamentales d’essais et de mesures - Partie 3-4: Examens et mesures - Affaiblissement
L'IEC 61300-3-4:2023 décrit les différentes méthodes disponibles qui permettent de mesurer l’affaiblissement des composants optiques. Toutefois, elle n’est applicable ni aux mesurages de l’affaiblissement dû à l’accouplement aléatoire décrits dans l’IEC 61300-3-34 et l’IEC 61300-3-45 ni aux mesurages de l’affaiblissement des dispositifs de multiplexage par répartition en longueur d’onde à forte densité (DWDM - dense wavelengths division multiplexer) décrits dans l’IEC 61300-3-29. Cette quatrième édition annule et remplace la troisième édition parue en 2012. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) ajout de l’Article 3 relatif aux termes, définitions et abréviations;
b) ajout d'une nouvelle méthode de mesure LSPM, la méthode par insertion (D);
c) ajout de l’Annexe A qui décrit le mesurage de l'affaiblissement de la fibre multicœur;
d) modification de la méthode d'essai de référence par insertion C et de la méthode d'essai alternative par substitution ou par insertion D pour l’appareil de mesure de la puissance et le DUT de type 4.
Le contenu du corrigendum de juin 2023 a été pris en considération dans cet exemplaire.

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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition IEC 61300-3-4:2012. A vertical bar appears in the margin
wherever a change has been made. Additions are in green text, deletions are in
strikethrough red text.
IEC 61300-3-4 has been prepared by subcommittee 86B: Fibre optic interconnecting devices
and passive components, of IEC technical committee 86: Fibre optics. It is an International
Standard.
This fourth edition cancels and replaces the third edition published in 2012. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) addition of Clause 3 containing terms, definitions and abbreviated terms;
