CONNECTORS FOR ELECTRICAL AND ELECTRONIC EQUIPMENT –
Part 1: Detail specification for two-way, shielded or unshielded, free and
fixed connectors – Mechanical mating information, pin assignment and
additional requirements for Type 1 copper LC style
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 63171-1 has been prepared by subcommittee 48B: Electrical

connectors of IEC technical committee 48: Electrical connectors and mechanical structures for

electrical and electronic equipment.
The text of this International Standard is based on the following documents:
FDIS Report on voting

electrical and electronic components, can be found on the IEC website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

INTRODUCTION

The International Electrotechnical Commission (IEC) draws attention to the fact that it is

claimed that compliance with this document may involve the use of a patent concerning

contact mating surface dimensions given in 5.1.

The IEC takes no position concerning the evidence, validity and scope of this patent right.

The holder of the patent right on contact mating surface dimensions in 5.1 has assured the

IEC that they are willing to give free licences to applicants throughout the world. In this

respect, the statement of the holder of this patent right is registered with the IEC

Information may be obtained from:
CommScope Technologies, LLC
501 Shenandoah Drive
Shakopee, Minnesota
USA 55379

Attention is drawn to the possibility that some of the elements of this International Standard

may be the subject of patent rights other than those identified above. IEC shall not be held

responsible for identifying any or all such patent rights.

ISO (www.iso.org/patents) and IEC (http://patents.iec.ch) maintain on-line data bases of

patents relevant to their standards. Users are encouraged to consult the data bases for the

most up to date information concerning patents.

IEC 63171 is the base specification of the whole series. Subsequent specifications do not

duplicate information given in the base document, but list only additional requirements. For

complete specification regarding a component of a higher number document the base

numbered documents should be considered as well. The following diagram (see Figure 1)

shows the interrelation of the documents:

4 Technical information
4.1 Compatibility level – Interoperability

Interoperability of connectors from different sources that are in compliance to this document is

assured as a pre-requisite by compliance with the specified interface dimensions
(intermateability) and by the relevant signal integrity tests specified.

The design of this copper LC style connector contains features in both the free and fixed

connectors that prevent intermateability with a standard LC fibre optic connector according to

IEC 61754-20. The key feature in the fixed connector, as shown in Figure 4c), prevents the

insertion of an LC fibre optic connector. The height of the free connector, shown
