Fibre optic interconnecting devices and passive components - Connector optical interfaces for single-mode fibres - Part 1: Optical interfaces for dispersion unshifted fibres - General and guidance

This part of IEC 61755 covers dispersion unshifted single-mode fibre optic connection interfaces. It includes references, document structure details, definitions, and standardised optical connection grades. The grades are based on random mated connections between two optical connector populations according to prescribed characteristics including fibre mode field diameter (MFD) mismatch. It also defines standardized test methods where appropriate.

Dispositifs d’interconnexion et composants passifs fibroniques - Interfaces optiques avec connecteurs pour fibres unimodales - Partie 1: Interfaces optiques pour fibres à dispersion non décalée - Généralités et recommandations

L'IEC 61755-1:2022 document traite des interfaces de connexion fibroniques unimodales à dispersion non décalée. Il comprend des références, des précisions sur la structure du document, des définitions et des classes de connexion optique normalisées. Les classes sont fondées sur des connexions aléatoires entre deux populations de connecteurs optiques selon des caractéristiques exigées, y compris la désadaptation du diamètre du champ de mode (MFD - mode field diameter) de la fibre. Il définit également les méthodes d’essais normalisées, s’il y a lieu. Cette deuxième édition annule et remplace la première édition parue en 2005. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: - suppression de la Figure 2, de la Figure 3 et du Tableau 4, et prise en considération de parties du texte dans leur intégralité; - ajout de la méthode d’essai relative à la connexion aléatoire de connecteurs multifibres; - présentation de la nomenclature des variantes de l'emplacement du cœur spécifié; - remplacement de la plage limitée de MFD qui est maintenant conforme à la plage complète de MFD spécifiée dans l’IEC 60793-2-50; - remplacement des références aux normes de fiabilité par des rapports techniques de fiabilité; - nouveau titre général pour la série.

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.
