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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 62153-1-1 has been prepared by subcommittee 46A: Coaxial
cables, of IEC technical committee 46: Cables, wires, waveguides, r.f. connectors, r.f and
microwave passive components and accessories.
This standard cancels and replaces IEC/PAS 62260 published in 2001. This first edition
constitutes a technical revision.

INTRODUCTION
This part of IEC 62153 has been developed from IEC/PAS 62260 . It is intended to be used
initially for coaxial cables and to be developed in the future to include requirements for all
metallic communication cables.
Irregularities in a transmission line, especially in r.f. cables, cause reflections that will lead to
forward echoes. Such forward echoes may cause considerable signal transmission
disturbance in analogue and digital systems. The magnitude of such irregularities of the
cables need to be limited in cabling systems, for example, in CATV networks and therefore
need to be determined.
One method to determine such irregularities is to use analogue measuring techniques (Time
Domain Reflection (TDR)), as described in 11.18 of IEC 61196-1. Although this is a well-
known test method, instrumentation with high sensitivity is no longer available on the market.
With a modern vector network analyser, offering sufficient dynamic range, the pulse return
loss can be determined.
This is achieved by measuring the return loss of the cable in the frequency domain as
described in 11.12 of IEC 61196-1 and transforming the results into the time domain by using
the Inverse Discrete Fourier Transformation (IDFT). By integrating the pulse response data
over time, the step response can be calculated.
The network analyser can be used for both the measurement of the return loss and the
pulse/step return loss without preparing the CUT twice. This method can therefore save time
and the cost of additional instrumentation and offers a simple and easy method for the
detection of signal transmission irregularities inside a cable.
This method also offers higher accuracy and higher sensitivity than the analogue TDR
method.
