Fibre optic interconnecting devices and passive components - Fibre optic connector optical interfaces - Part 1: Enhanced macro bend loss multimode 50 µm core diameter fibres - General and guidance

This part of IEC 63267 covers multimode 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 the core diameter and numerical aperture mismatches. The document describes the rules under which an optical interface is created. It also defines standardised test methods where appropriate.

Dispositifs d'interconnexion et composants passifs fibroniques – Interfaces optiques de connecteurs fibroniques - Partie 1: Fibres multimodales de diamètre de coeur de 50 μm à performances améliorées en matière de pertes par macrocourbures – Généralités et recommandations

IEC 63267-1:2023 couvre les interfaces de connexion fibroniques multimodales de diamètre de cœur de 50 µm à performances améliorées en matière de pertes par macrocourbures. Elle comprend les références, les détails de la structure du document, les définitions et les classes normalisées de connexion optique. Les classes sont fondées sur des connexions accouplées sans choix préalable entre deux populations de connecteurs optiques selon des caractéristiques exigées, notamment le diamètre du cœur et les défauts d'adaptation d'ouverture numérique. Le présent document décrit les règles qui régissent la création d'une interface optique. Il définit également les méthodes d'essais normalisées, le cas échéant.

Ta del standarda IEC 63267 obravnava vmesnike za povezovanje večžilnih optičnih vlaken. Zajema sklicevanja, podrobnosti o strukturi dokumenta, definicije in standardizirane razrede optičnih povezav.
Razredi temeljijo na naključno spojenih povezavah med dvema populacijama optičnih konektorjev glede na predpisane značilnosti, vključno s premerom jedra in neujemanji numeričnih apertur.
V dokumentu so opisana pravila za ustvarjanje optičnega vmesnika.
Poleg tega opredeljuje standardizirane preskusne metode, kjer je to ustrezno.

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
