FOREWORD

1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)

form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC

participate in the development of International Standards through technical committees established by the

respective organization to deal with particular fields of technical activity. ISO and IEC technical committees

collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in

liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have

established a joint technical committee, ISO/IEC JTC 1.

2) The formal decisions or agreements of IEC and ISO 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 and ISO member bodies.

3) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted

by IEC National Committees and ISO member bodies in that sense. While all reasonable efforts are made to

ensure that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO 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 and ISO member bodies undertake to

apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and

regional publications. Any divergence between any ISO, IEC or ISO/IEC publication and the corresponding

national or regional publication should be clearly indicated in the latter.

5) ISO and IEC do not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. ISO or IEC are 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 ISO or its directors, employees, servants or agents including individual experts

and members of their technical committees and IEC National Committees or ISO member bodies 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 of, use of, or reliance upon, this ISO/IEC

publication or any other IEC, ISO or ISO/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 ISO/IEC publication may be the subject of

patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

International Standard ISO/IEC 14763-4 has been prepared by subcommittee SC 25:

Interconnection of information technology equipment, of ISO/IEC joint technical committee 1:

Information technology.

This International Standard has been approved by vote of the member bodies, and the voting

results can be obtained from the address given on the second title page.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

INTRODUCTION

Balanced cabling is constructed for connecting equipment using free connectors. It is known

that field termination in all parts of the channel has an influence on the channel performance.

Poor termination can cause problems in the channel performance and may affect reliable data

transmission.

Until now, a verification of the field terminated cabling was done by measurement of the

channel performance of Channel Class D or E according to ISO/IEC 11801-1. The

measurement of Channel Class D or E excludes the connections at the end of the cable. The

measurement of Channel Class D or E does not identify the influence to the performance

caused by bad terminations of the connections at the end.

The measurement of performance of end-to-end (E2E) link includes the termination on both

ends of balanced cabling.

This document describes the measurement of E2E links of two- and four-pair balanced

cabling of 100 MHz of Class D and 250 MHz of Class E using laboratory and field tester

measurement procedures.
The performance of E2E links is described in ISO/IEC TR 11801-9902.

1 Scope

This part of ISO/IEC 14763 specifies the measurement at frequencies of E2E links of two- and

four-pair balanced cabling of 100 MHz of Class D and 250 MHz of Class E including free

connectors which terminate two and four pairs in both field and laboratory conditions.

The specifications for E2E links are described in ISO/IEC TR 11801-9902.

This document specifies laboratory and field measurement procedures. The requirements for

accuracy to measure cabling parameters identified in ISO/IEC TR 11801-9902 are provided in

IEC 61935-1 and IEC 61935-2.
