Fibre optic interconnecting devices and passive components - Fibre optic connector optical interfaces - Part 2-5: Connection of non-dispersion shifted single-mode angled physically contacting fibres for reference connector application (IEC 61755-2-5:2015)

This part of IEC 61755 defines a set of prescribed conditions that should be maintained in
order to satisfy the requirements of angled polished reference connections.
The prescribed conditions include dimensional limits and optical fibre requirements of the
optical interface to meet specific requirements for reference connection (plugs and adaptors)
used for attenuation measurements.
Two different grades for reference connections are defined in this standard. The use of each
of these grades depends on the application and on the targeted attenuation measurement
uncertainty. The model uses a Gaussian distribution of light intensity over the specified
restricted mode field diameter (MFD) range.
This standard is intended to be used for shipping and acceptance inspections.
The reference connector plug is specified for B1.1, B1.3 and B6 fibres as specified in
IEC 60793-2-50.
The use of the reference connector plug would not be recommended where classification of
fibre is difficult, for example construction and maintenance of cable plant.

IEC 61755-2-5:2015 définit un ensemble de conditions prescrites qu’il convient de respecter afin de satisfaire aux exigences relatives aux connexions de référence avec angle, avec polissage. Les conditions prescrites comprennent les limites dimensionnelles et les exigences relatives aux fibres optiques de l’interface optique en vue de satisfaire aux exigences spécifiques relatives aux connexions de référence (fiches et raccords) utilisées pour les mesures de l’affaiblissement. Deux classes différentes de connexions de référence sont définies dans la présente norme. L’utilisation de chacune de ces classes dépend de l’application et de l’incertitude de mesure de l’affaiblissement visée. Le modèle utilise une distribution gaussienne de l’intensité du rayonnement lumineux sur la plage de diamètres du champ de mode (MFD[1], mode field diameter) restreinte spécifiée. La présente norme est destinée à être utilisée pour les contrôles d’expédition et de réception. La fiche de connecteur de référence est spécifiée pour les fibres B1.1, B1.3 et B6 comme spécifié dans l’IEC 60793-2-50. L’utilisation de la fiche de connecteur de référence n’est pas recommandée dans le cas où la classification des fibres est difficile, par exemple concernant la construction et la maintenance de câbles installés.

Optični spojni elementi in pasivne komponente - Optični vmesniki konektorja optičnih vlaken - 2-5. del: Povezava enorodnih kotnih fizično dotikajočih se vlaken z nepremaknjeno disperzijo za aplikacijo v obliki referenčnega konektorja (IEC 61755-2-5:2015)

Ta del standarda IEC 61755 določa sklop predpisanih pogojev, ki naj bi se izpolnjevali za doseganje zahtev za kotne polirane referenčne povezave. Predpisani pogoji zajemajo dimenzijske omejitve in zahteve za optična vlakna optičnega vmesnika za izpolnjevanje posebnih zahtev za referenčno povezavo (vtiči in pretvorniki), ki se uporabljajo za meritve slabljenja. V tem standardu sta določena dva različna razreda za referenčne povezave. Raba vsakega razreda je odvisna od uporabe in negotovosti ciljnih meritev slabljenja. Model uporablja Gaussovo porazdelitev intenzivnosti svetlobe v določenem omejenem razponu premera polja načina (MFD).
Ta standard je namenjen uporabi za prevoz in inšpekcijske preglede sprejemljivosti. Referenčni konektorski vtič je določen za vlakna B1.1, B1.3 in B6, kot je določeno v standardu IEC 60793-2-50. Uporaba referenčnega konektorskega vtiča se ne priporoča, kadar je klasifikacija vlakna težka, na primer pri gradnji in vzdrževanju kabelske inštalacije.

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 61755-2-5 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
The text of this standard is based on the following documents:
