Fibre optic interconnecting devices and passive components - Fibre optic isolators - Part 1: Generic specification

IEC 61202-1:2016 applies to isolators used in the field of fibre optics, all exhibiting the following features:
- they are non-reciprocal optical devices, in which each port is either an optical fibre or fibre optic connector;
- they are passive devices containing no opto-electronic or other transducing elements;
- they have two optical ports for directionally transmitting optical power. This fourth edition cancels and replaces the third edition published in 2009. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the terms and definitions were reconsidered;
- quality assessment level was deleted from classification;
- the clause numbers of Annexes A and B have been rearranged.

IEC 61202-1:2016 s’applique aux isolateurs utilisés dans le domaine fibronique, possédant tous les caractéristiques suivantes:
- ce sont des dispositifs optiques non réciproques, dans lesquels chaque port est soit une fibre optique soit un connecteur fibronique;
- ce sont des dispositifs passifs qui ne contiennent pas d’éléments optoélectroniques ou d’autres éléments transducteurs;
- ils ont deux ports optiques pour les puissances optiques à émission directionnelle.
Cette quatrième édition annule et remplace la troisième édition parue en 2009. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- les termes et les définitions ont été revus;
- le niveau d’évaluation de la qualité a été supprimé de la classification;
- les numéros d'article des Annexes A et B ont été réagencés.
Mots clés: isolateurs utilisés dans le domaine fibronique

FIBRE OPTIC INTERCONNECTING DEVICES
AND PASSIVE COMPONENTS –
FIBRE OPTIC ISOLATORS –
Part 1: Generic specification
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 som
