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 62664-1-1 has been prepared by subcommittee 86B: Fibre optic

3 Description
3.1 General
The LC-PC duplex connector is a single position plug connector set of plug/adaptor/plug
configuration, characterized by cylindrical, spring loaded butting ferrules of 1,25 mm nominal
diameter and a latched push-pull coupling mechanism. The optical alignment mechanism of
the connectors is of a resilient sleeve style.
This standard contains the initial, start-of-life dimensional, optical, mechanical and
environmental performance requirements which a terminated and assembled multimode
resilient alignment sleeve LC-PC duplex connector set (plug/adaptor/plug) needs to meet in
order for it to be categorized as an International Standard product.
3.1.1 Intermateability and interoperation
Although all products conforming to the requirements of this standard will inter-mate, the
resulting level of random attenuation will be at a common level of performance i.e. the
attenuation of a mated pair will be limited by the worst of the two connectors. This will be true,
irrespective of the manufacturing source(s) of the product.
A simplex plug can be connected in a duplex adaptor without degrading the level of
performance.
3.1.2 Operating environment
The tests selected combined with the severities and durations are representative of an indoor
environment typically, but not limited to, that found in generic cabling on commercial premises
as defined in ISO/IEC 11801 and specified as IEC category C.
3.1.3 Reliability
Whilst the anticipated service life expectancy of the product in this environment is 10years,
compliance with this standard does not guarantee the reliability of the product. This should be
predicted using a recognized reliability assessment programme.

62664-1-1 © IEC:2013 – 9 –
3.1.4 Quality assurance
Compliance with this standard does not guarantee the manufacturing consistency of the
product. This should be maintained using a recognized quality assurance programme.
3.2 Plug
The plug features a cylindrical zirconia ceramic ferrule and a latched push-pull mechanism. It
has a single male key which is
