Fibre optic interconnecting devices and passive components - Connector optical interfaces for enhanced macro bend multimode fibres - Part 2-2: Connection parameters of physically contacting 50 μm core diameter fibres - Non-angled and angled for reference connector applications

IEC 63267-2-2:2024 defines the dimensional limits of an optical interface for reference connections necessary to meet specific requirements for fibre-to-fibre interconnection of non-angled and angled polished multimode reference connectors intended to be used for attenuation measurements in the field or factory. Several grades of reference connections are defined in this document. The multimode reference connections are terminated to restricted IEC 60793-2-10 A1-OM2b to A1-OM5b fibre at the 850 nm band only. The geometrical dimensions and tolerances of the specified reference connections have been developed primarily to limit the variation in measured attenuation between multiple sets of two reference connectors, and therefore to limit the variation in measured attenuation between randomly chosen reference connectors when mated with connectors in the field or factory.

IEC 63267-2-2: 2024 définit les limites dimensionnelles d'une interface optique pour les connexions de référence nécessaires pour satisfaire aux exigences spécifiques d'interconnexion entre fibres de connecteurs de référence multimodaux polis inclinés et non inclinés destinés à être utilisés pour les mesurages d'affaiblissement sur le terrain ou en usine. Le présent document définit plusieurs classes de connexions de référence. Les connexions de référence multimodales sont raccordées sur une fibre restreinte A1-OM2b à A1-OM5b de l’IEC 60793-2-10 dans la bande de 850 nm uniquement. Les dimensions géométriques et les tolérances des connexions de référence spécifiées ont été développées principalement pour limiter la variation de l'affaiblissement mesuré entre plusieurs ensembles de deux connecteurs de référence, et donc pour limiter la variation de l'affaiblissement mesuré entre des connecteurs de référence choisis de manière aléatoire lorsqu'ils sont accouplés avec des connecteurs sur le terrain ou en usine.

Standard IEC 63267-2-2:2024 določa dimenzijske mejne vrednosti optičnega vmesnika za referenčne konektorje za potrebe izpolnjevanja posebnih zahtev za spajanje vlaken pri nekotnih in kotnih poliranih mnogorodovnih referenčnih konektorjih, ki so namenjeni za meritve slabljenja na terenu ali v tovarni. V tem dokumentu je opredeljenih več razredov referenčnih povezav.
Mnogorodovne referenčne povezave so zaključene na omejeno vlakno A1-OM2b do A1-OM5b iz standarda IEC 60793-2-10 samo v območju 850 nm.
Geometrijske dimenzije in tolerance opredeljenih referenčnih povezav so bile razvite predvsem za to, da bi omejile razlike pri izmerjeni oslabitvi med več sklopi dveh referenčnih konektorjev in s tem omejile razlike pri izmerjeni oslabitvi med naključno izbranimi referenčnimi konektorji, kadar so ti spojeni s konektorji na terenu ali v tovarni.

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 c
