Fibre optic interconnecting devices and passive components - Fibre optic connector optical interfaces - Part 3-32: Optical interface, 8 degrees angled PC, thermoset epoxy rectangular ferrule, single mode fibres

This part of IEC 61755 defines certain dimensional limits of an angled PC rectangular
thermoset (TS) ferrule optical interface in order to meet specific requirements for fibre-to-fibre
interconnection. Ferrules made from the material specified in this standard are suitable for
use in categories C, U, E, and O as defined in IEC 61753-1.
Ferrule interface dimensions and features are contained in the IEC 61754 series, which deals
with fibre optic connector interfaces.

L'IEC 61755-3-32:2015 définit un certain nombre de limites dimensionnelles des interfaces optiques à férules rectangulaires en époxy thermodurcissable (TS), PC avec angle afin de satisfaire aux exigences particulières d'une interconnexion fibre à fibre. Les férules réalisées dans le matériau spécifié dans la présente norme sont adaptées à une utilisation dans les catégories C, U, E et O définies dans l'IEC 61753-1. Les dimensions et les caractéristiques des interfaces des férules sont contenues dans la série IEC 61754 qui traite des interfaces de connecteurs pour fibres optiques.

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 61755-3-32 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This first edition cancels and replaces IEC PAS 61755-3-32 published in 2007. This edition
constitutes a technical revision.
The text of this standard is based on the following documents:

A list of all parts of the IEC 61755 series, under the general title Fibre optic interconnecting
devices and passive components – Connector optical interfaces, can be found on the IEC
website.
Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
