(Main)Fibre optic interconnecting devices and passive components - Connector optical interfaces for enhanced macro bend multimode fibres - Part 2-1: Connection parameters of physically contacting 50 µm core diameter fibres - Non-angled (IEC 63267-2-1:2024)
Fibre optic interconnecting devices and passive components - Connector optical interfaces for enhanced macro bend multimode fibres - Part 2-1: Connection parameters of physically contacting 50 µm core diameter fibres - Non-angled (IEC 63267-2-1:2024)
IEC 63267-2-1:2024 defines a set of specified conditions for an enhanced macro bend of 50/125 µm, graded index multimode fibre optic connection that is maintained in order to satisfy the requirements of attenuation and return loss performance in a randomly mated pair of polished physically contacting (PC) fibres.
An encircled flux (EF) compliant launch condition in accordance with IEC 61300-1, at an operational wavelength of 850 nm, is used for determination of performance grades, based on lateral fibre core offset, numerical aperture (NA) mismatch, and fibre core diameter (CD) variation.
Fibre core angular offset is considered insignificant given the state-of-the-art and is excluded as a factor for attenuation estimation. Attenuation and return loss performance grades are defined in IEC 63267-1.

IEC 63267-2-1:2024 définit un ensemble de conditions spécifiées pour les connexions fibroniques multimodales à gradient d’indice, de 50/125 µm améliorées en macrocourbures, afin de satisfaire aux exigences de performance d'affaiblissement et d'affaiblissement de réflexion dans une paire à accouplement sans choix préalable de fibres polies à contact physique (PC).
Une condition d’injection conforme au flux inscrit (EF, encircled flux) selon l’IEC 61300‑1, à une longueur d’onde de fonctionnement de 850 nm, est utilisée en vue de déterminer les classes de performances, fondées sur le décalage latéral du cœur de la fibre, la désadaptation de l'ouverture numérique (NA, numerical aperture) et la variation du diamètre du cœur de la fibre (CD, core diameter).
Le décalage angulaire du cœur de la fibre est considéré comme négligeable compte tenu de l'état de l’art et il est exclu à titre de facteur pour l'estimation de l'affaiblissement. Les classes d'affaiblissement et d'affaiblissement de réflexion sont définies dans l’IEC 63267‑1.

Standard IEC 63267-2-1:2024 opredeljuje nabor določenih pogojev za povezavo z izboljšanim gradientnim mnogorodovnim optičnim vlaknom zaradi upogibanja s premerom jedra 50/125 µm, da so izpolnjene zahteve glede slabljenja in zmogljivosti povratne izgube v naključno povezanem paru poliranih fizično staknjenih (PC) vlaken.
Zagonski pogoj, ki ustreza obdanemu pretoku (EF) v skladu s standardom IEC 61300-1, pri delovni valovni dolžini 850 nm, se uporablja za določanje razredov zmogljivosti na podlagi stranskega odmika jedra vlakna, neujemanja numeričnih apertur (NA) in spremembe premera jedra vlakna (CD).
Kotni odmik jedra vlakna glede na trenutno stanje ni pomemben in je izključen kot dejavnik za oceno slabljenja. Razredi zmogljivosti slabljenja in povratne izgube so opredeljeni v standardu IEC 63267-1.

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 incl
