EN 61290-10-1:2009

Optical amplifiers - Test methods - Part 10-1: Multichannel parameters - Pulse method using an optical switch and optical spectrum analyzer

IEC 61290-10-1:2009 applies to optical fibre amplifiers (OFAs) using active fibres, containing rare-earth dopants, currently commercially available. The uniform requirements for accurate and reliable measurements of the signal-spontaneous noise figure as defined in 3.1.18 of IEC 61291-1 are established. The test method independently detects amplified signal power and amplified spontaneous emission (ASE) power by launching optical pulses into the OFA under test and synchronously detecting 'on' and 'off' levels of the output pulses by using an optical sampling switch and an optical spectrum analyzer (OSA). This edition is a technical revision with updated references and cautions on proper use of the procedure. This publication is to be read in conjunction with IEC 61291-1:2006.

Prüfverfahren für Lichtwellenleiter-Verstärker - Teil 10-1: Mehrkanalparameter - Pulsmethode bei Verwendung eines optischen Schalters und optischen Spektralanalysators

Amplificateurs optiques - Méthodes d'essai - Partie 10-1: Paramètres à canaux multiples - Méthode d’impulsion utilisant un interrupteur optique et un analyseur de spectre optique

La CEI 61290-10-1:2009 s'applique aux amplificateurs optiques (AO) utilisant des fibres actives et des guides d'ondes, dopées aux terres rares, actuellement disponibles sur le marché. L'objet de la présente norme est d'établir des exigences uniformes en vue de mesures précises et fiables du facteur de bruit spontané-signal défini dans la CEI 61291-1. La méthode d'essai détecte indépendamment la puissance du signal amplifiée et la puissance d'émission spontanée amplifiée (ESA) en lançant des impulsions optiques dans l'AO en essai et en détectant en synchronisme les niveaux '1' et '0' des impulsions de sortie à l'aide d'un interrupteur d'échantillonnage optique et un analyseur de spectre optique (ASO). Cette deuxième édition annule et remplace la première édition parue en 2003. C'est une révision technique avec des références mises à jour, et des mises en garde concernant la bonne utilisation des procédures. Cette publication doit être lue conjointement avec la CEI 61291-1:2006.

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.
