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 was prepared by subcommittee 25: Interconnection of

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

technology.

This second edition cancels and replaces the first edition published in 2018. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

• measurement of the transmission performance of modular plug terminated link (MPTL) and

direct attach cabling were added.
• Additional requirements of test head designs of E2E link were introduced.

INTRODUCTION

The testing of balanced cabling channels in accordance with ISO/IEC 11801-1 does not verify

the performance of the free connector at each end of the channel.

This document describes the measurement of three cabling structures which verifies the

performance of their terminating connectors. These are:
a) end-to-end (E2E) link of ISO/IEC 11801-3,
b) modular plug terminated link (MPTL) of ISO/IEC TR 11801-9910,
c) direct attach cabling of ISO/IEC TR 11801-9907.

This measurement includes the transmission performance of the connector components which

terminate the cabling under test.
