Fibre optic interconnecting devices and passive components - Connector optical interfaces - Part 6-2: Connection of 50 μm core diameter multimode physically contacting fibres - Non-angled for reference connector application, at wavelength of 850 nm using selected A1a fibre only (IEC 61755-6-2:2018)

This part of the IEC 61755 defines the dimensional limits of an optical interface for reference
connectors necessary to meet specific requirements for fibre-to-fibre interconnection of nonangled
polished multimode reference connectors with cylindrical ferrules intended to be used
for attenuation measurements in the field or factory.
One grade of reference connector is defined in this document. The reference connector is
terminated to selected IEC 60793-2-10:2015 A1a fibre. The geometrical dimensions and
tolerances of the specified reference connector 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.

Dispositifs d’interconnexion et composants passifs fibroniques - Interfaces optiques de connecteurs - Partie 6-2: Connexion de fibres multimodales en contact physique d’un diamètre de coeur de 50 μm - Connecteurs de référence sans angle, à une longueur d’onde de 850 nm et en utilisant uniquement les fibres A1a choisies (IEC 61755-6-2:2018)

IEC 61755-6-2: 2018 définit les limites dimensionnelles d’une interface optique pour les connecteurs de référence, qui sont nécessaires pour satisfaire aux exigences particulières des interconnexions fibre à fibre des connecteurs de référence multimodaux polis sans angle à férule cylindrique, destinés à être utilisés pour les mesures d’affaiblissement sur le terrain ou en usine. Le présent document définit une classe de connecteur de référence. Le connecteur de référence est raccordé à des fibres A1a choisies conformément à l’IEC 60793-2-10:2015. Les dimensions géométriques et les tolérances du connecteur de référence spécifié ont été développées principalement pour limiter les écarts au niveau de l’affaiblissement mesuré entre les différentes paires de connecteurs de référence, et donc pour limiter les écarts au niveau de l’affaiblissement mesuré entre des connecteurs de référence choisis de manière aléatoire, lorsqu’ils sont accouplés à des connecteurs sur le terrain ou en usine.
Mots clés : interface optique, interconnexions fibre à fibre

Optični spojni elementi in pasivne komponente - Vmesniki optičnih konektorjev - 6-2. del: Spajanje mnogorodovnih vlaken s premerom jedra 50 µm s fizičnim stikom - Za aplikacijo referenčnega pravokotnega konektorja pri valovni dolžini 850 nm z uporabo samo izbranih vlaken A1a (IEC 61755-6-2:2018)

Ta del standarda IEC 61755 določa dimenzijske mejne vrednosti optičnega vmesnika za referenčne priključke za potrebe izpolnjevanja posebnih zahtev za spajanje vlaken pri nekotnih poliranih mnogorodovnih referenčnih konektorjih s cilindričnimi tulkami, ki so namenjeni za meritve slabljenja na terenu ali v tovarni.
V tem dokumentu je opredeljen en razred referenčnih konektorjev. Referenčni konektor je zaključen na izbrano vlakno iz standarda IEC 60793-2-10:2015 A1a. Geometrijske dimenzije in tolerance opredeljenega referenčnega konektorja 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 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 61755-6-2 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
