(Main)Fibre optic interconnecting devices and passive components - Non-wavelength-selective fibre optic branching devices - Part 1: Generic specification
Fibre optic interconnecting devices and passive components - Non-wavelength-selective fibre optic branching devices - Part 1: Generic specification
IEC 60875-1:2024 applies to non-wavelength-selective fibre optic branching devices, all exhibiting the following features:
- they are passive, in that they contain no optoelectronic or other transducing elements;
- they have three or more ports for either the entry or exit, or both, of optical power, and share optical power among these ports in a predetermined fashion;
- the ports are optical fibres, or optical fibre connectors.
This document establishes uniform requirements for the optical, mechanical and environmental properties. This seventh edition cancels and replaces the sixth edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) removal of variant and reference extensions in clause classification
b) removal of specification system in clause documentation
c) removal of interface standards, reliability standards and interlinking in clause standardization system
Dispositifs d'interconnexion et composants passifs fibroniques - Dispositifs de couplage fibroniques ne dépendant pas de la longueur d'onde - Partie 1: Spécification générique
L'IEC 60875-1:2024 s’applique aux dispositifs de couplage fibroniques qui ne dépendent pas de la longueur d’onde. Tous présentent les caractéristiques suivantes:
- ils sont passifs, au sens où ils ne contiennent aucun élément optoélectronique ou transducteur;
- ils ont trois ports ou plus pour l'entrée ou la sortie de la puissance optique, ou pour les deux, et ils partagent la puissance optique parmi ces ports, selon une modalité prédéterminée;
- les ports sont des fibres optiques ou des connecteurs à fibres optiques.
Le présent document établit des exigences uniformes relatives aux propriétés optiques, mécaniques et environnementales. Cette septième édition annule et remplace la sixième édition parue en 2015. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) suppression des variantes et des extensions de référence dans la classification des articles;
b) suppression de la structure des spécifications dans la documentation des articles;
c) suppression des normes d’interface, des normes de fiabilité et des correspondances croisées dans le système de normalisation des articles.

FIBRE OPTIC BRANCHING DEVICES –
Part 1: Generic specification
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition IEC 60875-1:2015. A vertical bar appears in the margin
wherever a change has been made. Additions are in green text, deletions are in
strikethrough red text.
IEC 60875-1 has been prepared by IEC technical committee 86B: Fibre optic interconnecting
devices and passive components. It is an International Standard.
This seventh edition cancels and replaces the sixth edition published in 2015. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) removal of variant and reference extensions in clause classification
b) removal of specification system in clause documentation
c) removal of interface standa
