Part 3-4: Examinations and measurements – Attenuation

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 61300-3-4 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This third edition cancels and replaces the second edition published in 2001. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) revision of source conditions, launch conditions and power meter parameters;
b) addition of safety recommendations;
c) removal of launch condition details for multimode fibres, now referenced in 61300-1.

Part 3-4: Examinations and measurements – Attenuation



1 Scope
This part of IEC 61300 describes the various methods available to measure the attenuation of
optical components. It is not, however, applicable to dense wavelength division multiplexing
(DWDM) components, for which IEC 61300-3-29 should be used.

3 General description
3.1 General
Attenuation is intended to give a value for the decrease of useful power, expressed in
decibels, resulting from the insertion of a device under test (DUT), within a length of optical
fibre cable. The term insertion loss is sometimes used in place of attenuation.
The DUT may have more than two optical ports. However, since an attenuation measurement
is made across only two ports, the DUTs in this standard shall be described as having two
ports. Eight different DUT configurations are described. The differences between these
configurations are primarily in the terminations of the optical ports. Terminations may consist
of bare fibre, a connector plug, or a receptacle.
The reference method for measuring attenuation is with an optical power meter. Optical time
domain reflectometry (OTDR) measurements are presented as an alternative method. Three
variations in the measurement of attenuation with a power meter are presented. The reference

and alternative methods to be used for each DUT configuration are defined in Table 3.
Different test configurations and methods will result in different accuracies of
