FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The 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.

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.
