Fibre optics - Multimode launch conditions - Part 1: Launch condition requirements for measuring multimode attenuation
IEC 62614-1: 2020 describes the launch condition requirements used for measuring multimode attenuation in passive components and in installed cable plants. In this document, the fibre types that are addressed include category A1-OMx, where x = 2, 3, 4 and 5 (50 µm/125 µm), and A1-OM1 (62,5 µm/125 µm) multimode fibres, as specified in IEC 60793-2-10. The nominal test wavelengths detailed are 850 nm and 1 300 nm. This document can be suitable for multimode attenuation measurements for other multimode categories and/or other wavelengths, but the source condition for other categories and wavelengths are not defined here. The purpose of these requirements is as follows:
to ensure consistency of field measurements when different types of test equipment are used;
to ensure consistency of factory measurements when different types of test equipment are used;
to ensure consistency of field measurements when compared with factory measurements. This document describes launch condition requirements for optical attenuation using sources with a controlled encircled flux (EF).

Fibronique - Conditions d’injection en multimodal - Partie 1 : Exigences des conditions d'injection pour la mesure de l'affaiblissement en multimodal
IEC 62614-1:2020 décrit les exigences relatives aux conditions d’injection utilisées pour la mesure de l’affaiblissement en multimodal, dans des composants passifs et dans des installations câblées. Les types de fibres qui relèvent du présent document comprennent les fibres optiques multimodales des catégories A1-OMx, où x = 2, 3, 4 et 5 (50 µm/125 µm), et A1-OM1 (62,5 µm /125 µm), spécifiées dans l’IEC 60793-2-10. Les longueurs d’onde d’essai nominales spécifiées sont 850 nm et 1 300 nm. Le présent document peut être approprié pour les mesures de l’affaiblissement en multimodal pour d’autres catégories de fibres multimodales et/ou pour d’autres longueurs d’onde, mais les conditions de la source pour ces autres catégories et longueurs d’onde n’y sont pas définies. Les exigences exposées ici ont pour objectif: - d’assurer la cohérence des mesures sur site, lorsque différents types d’équipements d’essai sont utilisés; - d’assurer la cohérence des mesures en usine lorsque des types différents d’équipements d’essai sont utilisés; - d’assurer la cohérence des mesures sur site lors des comparaisons avec les mesures en usine. Le présent document décrit les exigences relatives aux conditions d’injection pour l’affaiblissement optique en utilisant des sources qui ont un flux inscrit (EF) contrôlé. Cette première édition annule et remplace l'IEC 62614 parue en 2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'IEC 62614: a) Augmentation de la valeur du coefficient d'incertitude de la variation de l’affaiblissement Y pour une fibre dont le diamètre de cœur est de 50 µm à 1 300 nm, en raison des conditions d'injection, à deux fois la valeur antérieure; b) modifications de 3.4, 5.6 y compris le Tableau 5 et de certaines références, pour assurer la cohérence avec l'IEC 61280-4-1:2019; c) modifications des désignations des fibres multimodales pour assurer la cohérence avec l'IEC 60793-2-10:2019.

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 62614-1 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.
This first edition cancels and replaces IEC 62614, published in 2010, and constitutes a technical
revision.
This edition includes the following significant technical changes with respect to IEC 62614:
a) increase of the value of the uncertainty attenuation variation coefficient Y for 50 µm core
fibre at 1 300 nm, due to launch conditions, to twice the previous value;
b) changes to 3.4, 5.6, including Table 5, and some references to remain consistent with
IEC 61280-4-1:2019;
c) changes to multimode fibre references to be consistent with IEC 60793-2-10:2019.
