Optical amplifiers - Test methods - Part 1-1: Power and gain parameters - Optical spectrum analyzer method
IEC 61290-1-1:2020 is available as IEC 61290-1-1:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 61290-1-1:2020 applies to all commercially available optical amplifiers (OAs) and optically amplified modules. It applies to OAs using 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:
- nominal output signal power;
- gain;
- polarization-dependent gain (PDG);
- maximum output signal power;
- maximum total output power.
In addition, this document provides the test method of:
- 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 are standardized in IEC 61290-10 (all parts). 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.
Amplificateurs optiques - Méthodes d'essai - Partie 1-1: Paramètres de puissance et de gain - Méthode de l'analyseur de spectre optique
IEC 61290-1-1:2020 est disponible sous forme de IEC 61290-1-1:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L'IEC 61290-1-1:2020 s’applique à tous les amplificateurs optiques (OA: optical amplifier) et modules à amplification optique. Elle s’applique aux amplificateurs optiques utilisant des amplificateurs à fibres optiques (OFA: optical fibre amplifier) composés de fibres dopées aux terres rares ou utilisant l’effet Raman, des amplificateurs optiques à semiconducteurs (SOA: semiconductor optical amplifier) et des amplificateurs à guide d’onde optique plan (POWA: planar optical waveguide amplifier). L'objet du présent document est d'établir des exigences uniformes pour des mesurages précis et fiables, par le biais de la méthode d'essai de l'analyseur de spectre optique (OSA: optical spectrum analyzer), des paramètres d’amplificateurs optiques donnés ci-dessous, tels qu’ils sont définis dans l'IEC 61291-1:
- puissance nominale du signal de sortie;
- gain;
- gain dépendant de la polarisation (PDG: polarization-dependent gain);
- puissance maximale du signal en sortie;
- puissance totale de sortie maximale.
En outre, la présente norme fournit la méthode d'essai suivante:
- essai d'ondulation du gain (pour amplificateurs optiques à semiconducteurs).
NOTE Toutes les valeurs numériques suivies de (‡) sont des valeurs suggérées pour lesquelles le mesurage est assuré.
L’objet du présent document est spécifiquement centré sur les amplificateurs à un seul canal. Les méthodes d'essai pour les amplificateurs à canaux multiples sont normalisées dans la série IEC 61290-10 (toutes les parties). Cette quatrième édition annule et remplace la troisième édition parue en 2015, dont elle constitue une révision technique. La présente édition inclut la modification technique majeure suivante par rapport à l'édition précédente: ajout de techniques pour soumettre aux essais l'ondulation du gain des amplificateurs optiques à semiconducteurs.

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.
