Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 1: General and guidance
IEC 61300-1:2022 provides general information and guidance for the basic test and measurement procedures defined in IEC 61300-2 (all parts) and IEC 61300-3 (all parts) for interconnecting devices, passive components, mechanical splices, fusion splice protectors, fibre management systems and protective housings. This document is used in combination with the relevant specification which defines the tests to be used, the required degree of severity for each of them, their sequence, if relevant, and the permissible performance limits. In the event of conflict between this document and the relevant specification, the latter takes precedence. This fifth edition cancels and replaces the fourth edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- addition of the information of measurement uncertainties in 4.2.1;
- change of the requirements for attenuation variation in 4.2.2;
- addition of the multimode launch conditions of other fibres than A1-OM2, A1-OM3, A1-OM4, A1-OM5 and A3e in 10.4;
- addition of the multimode launch conditions of the planer waveguide in 10.6;
- splitting Annex A for EF and Annex B for EAF;
- correction of errors in the definitions of encircled flux and encircled angular flux.
Dispositifs d'interconnexion et composants passifs fibroniques - Procédures fondamentales d'essais et de mesures - Partie 1: Généralités et recommandations
L'IEC 61300-1:2022 donne des informations d'ordre général et des recommandations concernant les procédures fondamentales d’essai et de mesure définies dans l'IEC 61300-2 (toutes les parties) et l'IEC 61300-3 (toutes les parties) et applicables aux dispositifs d'interconnexion, aux composants passifs, aux épissures mécaniques, aux protecteurs d'épissures par fusion, aux systèmes de gestion des fibres et aux boîtiers de protection. Le présent document est utilisé avec la spécification applicable qui définit les essais à réaliser, le degré de sévérité exigé pour chacun d’eux, l'ordre dans lequel ils sont effectués, le cas échéant, et les limites des performances admissibles. Si le présent document et la spécification applicable sont en contradiction, c’est cette dernière qui prévaut. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- ajout d'informations sur les incertitudes de mesure en 4.2.1;
- modification des exigences pour la variation d'affaiblissement en 4.2.2;
- ajout des conditions d’injection en multimodal des fibres autres que A1-OM2, A1-OM3,
- A1-OM4, A1-OM5 et A3e en 10.4;
- ajout des conditions d’injection en multimodal du guide d'onde plan en 10.6;
- séparation de l'Annexe A pour l’EF et de l'Annexe B pour l’EAF;
- correction d'erreurs dans les définitions du flux inscrit et du flux angulaire inscrit.

DEVICES AND PASSIVE COMPONENTS –
BASIC TEST AND MEASUREMENT PROCEDURES –
Part 1: General and guidance
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 61300-1:2022. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.
