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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change has
been made. Additions are in green text, deletions are in strikethrough red text.

International Standard IEC 61290-1-1 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.
This fourth edition cancels and replaces the third edition published in 2015 and constitutes a
technical revision.
This edition includes the following significant technical change with respect to the previous
edition: addition of techniques to test gain ripple of SOAs.
The text of this International Standard is based on the following documents:
FDIS Report on voting
86C/1673/FDIS 86C/1687/RVD
Full information on the voting for the approval of this International Standard can be found in the
report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
This document is to be used in conjunction with IEC 61290-1 and IEC 61291-1.
A list of all parts of the IEC 61290 series, published under the general title Optical amplifiers –
Test methods 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
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this document using a colour printer.
OPTICAL AMPLIFIERS – TEST METHODS –
Part 1-1: Power and gain parameters –
Optical spectrum analyzer method
1 Scope
This part of IEC 61290 applies to all commercially available optical amplifiers (OAs) and
optically amplified modules. It applies to OAs using optically pumped fibres optical fibre
amplifiers (OFAs) based on either rare-earth doped fibres or on the Raman effect,
semiconductor OAs (SOAs) and planar optical waveguide amplifiers (POWAs).
The object of this document is to establish uniform requirements for accurate and reliable
measurements, by means of the optical spectrum analyzer (OSA) test method, of the following
OA parameters, as defined in IEC 61291-1:
a) nominal output signal power;
b) gain;
c) polarization-dependent gain (PDG);
d) maximum output signal power;
e) maximum total output power.
In addition, this document provides the test method of:
f) gain ripple (for SOAs).
NOTE All numerical values followed by (‡) are suggested values for which the measurement is assured.
The object of this document is specifically directed to single-channel amplifiers. Test methods
for multichannel amplifiers, one should refer to the are standardized in IEC 61290-10 (all parts)
