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 61754-4-1 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This bilingual version (2014-07) corresponds to the English version, published in 2003-01.
The text of this standard is based on the following documents:
FDIS Report on voting
86B/1760/FDIS 86B/1809/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
The French version of this standard has not been voted upon.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
IEC 61754 consists of multiple parts, under the general title Fibre optic connector interfaces.
– Part 1, entitled General and guidance, covers general information.
– Subsequent parts contain interfaces for various connector families.
The committee has decided that the contents of this publication will remain unchanged until
2007. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

FIBRE OPTIC CONNECTOR INTERFACES –

Part 4-1: Type SC connector family –
Simplified receptacle SC-PC connector interfaces

1 Scope
This part of IEC 61754 defines the standard interface dimensions of simplified receptacles for
the type SC family of connectors.
2 Description
The parent connector for the type SC connector family is a single-position plug which is
characterized by a cylindrical, spring-loaded butting ferrule(s) of 2,5 mm typical diameter, and
a push-pull coupling mechanism.
The simplified receptacles are made up of simplified receptacle housings and simplified plugs.
The simplified receptacle housings are used to retain the connector plug and mechanically
maintain the optical datum target of the plugs at a defined position within the simplified
receptacle housings. A spring is not included in the simplified plug. The simplified plug is
removed with aid of a tool. The optical alignment mechanism of the connector is of a resilient
sleeve style.
3 Interfaces
This standard contains the following standard interfaces.
– Interface 4-21: simplified receptacles housings interface
– Interface 4-22: simplified plugs interface
The simplified plug has a ferrule with a spherical polished ferrule endface, and realizes
physical contact (PC).
The following interfaces are intermateable:
Interface 4-21 mates with interface 4-22.
