This part of IEC 61290 applies to all commercially available optical amplifiers (OAs) and
optically amplified subsystems. It applies to OAs using optically pumped fibres (optical fibre
amplifiers (OFAs) based on either rare-earth doped fibres or on the Raman effect),
semiconductors (semiconductor optical amplifiers (SOAs)), and waveguides (planar optical
waveguide amplifiers (POWAs)). It is specifically directed to single-channel amplifiers. Test
methods for multichannel amplifiers are defined in the IEC 61290-10 series.
This document establishes uniform requirements for accurate and reliable measurements of the
following OA parameters, as defined in IEC 61291-1:2018, Clause 3:
a) nominal output signal power;
b) gain;
c) reverse gain;
d) maximum gain;
e) maximum gain wavelength;
f) maximum gain variation with temperature;
g) gain wavelength band;
h) gain wavelength variation;
i) gain stability;
j) polarization-dependent gain;
k) gain ripple (SOA only);
l) large-signal output stability;
m) saturation output power;
n) maximum output signal power;
o) maximum total output power.
NOTE 1 The applicability of the test methods described in this document to distributed Raman amplifiers is still
under study.
NOTE 2 All numerical values followed by (‡) are suggested values for which the measurement is assured. Other
values are acceptable if verified.

Elle est spécifiquement centrée sur les amplificateurs à un seul canal. Les méthodes d'essai pour les amplificateurs à canaux multiples sont définies dans la série IEC 61290-10.
Le présent document établit des exigences uniformes pour des mesures précises et fiables des paramètres d’AO donnés ci-dessous, tels qu’ils sont définis dans l'IEC 61291-1:2018, Article 3:
a) puissance nominale du signal de sortie;
b) gain;
c) gain inverse;
d) Gain maximal;
e) longueur d’onde du gain maximal;
f) variation maximale du gain en fonction de la température;
g) bande de longueur d’onde du gain;
h) variation du gain en fonction de la longueur d’onde;
i) stabilité du gain;
j) gain dépendant de la polarisation;
k) ondulation du gain (SOA uniquement);
l) stabilité de sortie grands signaux;
m) puissance de sortie en saturation;
n) puissance maximale du signal de sortie;
o) puissance de sortie totale maximale.
NOTE 1 L’applicabilité des méthodes d’essai décrites dans le présent document à des amplificateurs à effet Raman répartis est toujours à l'étude.

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.
IEC 61290-1 has been prepared by subcommittee 86C: Fibre optic systems and active devices,
of IEC technical committee 86: Fibre optics. It is an International Standard.
This second edition cancels and replaces the first edition published in 2014. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) specification of gain ripple as a new parameter;
b) specification of test method and test report for gain ripple measurements;
c) use of the term “measurement uncertainty” instead of “measurement accuracy”.

94 1 Scope
95 This part of IEC 61290 applies to all commercially available optical amplifiers (OAs) and
96 optically amplified subsystems. It applies to OAs using optically pumped fibres (OFAs based on
97 either rare-earth doped fibres or on the Raman effect), semiconductors (SOAs), and
98 waveguides (POWAs). It is specifically directed to single-channel amplifiers. Test methods for
99 multichannel amplifiers are defined in the IEC 61290-10 series.
100 This standard establishes uniform requirements for accurate and reliable measurements of the
101 following OA parameters, as defined in Clause 3 of IEC 61291-1:
102 a) nominal output signal power;
103 b) gain;
104 c) reverse gain;
105 d) maximum gain;
106 e) maximum gain wavelength;
107 f) maximum gain variation with temperature;
108 g) gain wavelength band;
109 h) gain wavelength variation;
110 i) gain stability;
111 j) polarization-dependent gain;
112 k) gain ripple (SOA only);
113 l) large-signal output stability;
114 m) saturation output power;
115 n) maximum output signal power;
116 o) maximum total output power.
117 NOTE 1 The applicability of the test methods described in the present standard to distributed Raman amplifiers is
118 still under study.
119 NOTE 2 All numerical values followed by (‡).are suggested values for which the measurement is assured. Other
120 values are acceptable if verified.

148 4 Optical power and gain test method
149 Three commonly practised procedures for quantifying the optical power and gain of an OA are
150 considered in this standard.
151 The aim of the first procedure (see IEC 61290-1-1) is to determine the optical power and gain
152 by means of the optical spectrum analyzer test method.
153 The aim of the second procedure (see IEC 61290-1-2) is to determine the optical power and
154 gain by means of an optical detector and an electrical spectrum analyzer.
155 The aim of the third procedure (see IEC 61290-1-3) is to determine the optical power and gain
156 by means of an optical power meter and an optical bandpass filter.
157 5 Optical power and gain parameters
158 The parameters listed below are required for gain and power:
159 a) Nominal output signal power: The nominal output signal power is given by the minimum
160 output signal optical power for an input signal optical power specified in the relevant detail
161 specification and under nominal operating conditions given in the relevant detail
162 specification. To find this minimum value, input and output signal power levels shall be
163 continuously monitored for a given duration of time and in presence of changes in the
164 state of polarization and other instabilities, as specified in the relevant detail specification.
165 The measurement procedures and calculations are described in each test method.
166 b) Gain: The measurement procedures and calculations are described in each test method.
