Annotation of standard text IEC 61290-3-2-ed.3.0 :
IEC 61290-3-2:2026 applies to all commercially available optical amplifiers (OAs), including OAs using optically pumped fibres (i.e. optical fibre amplifiers (OFAs) based on either rare-earth doped fibres or on the Raman effect), semiconductor optical amplifiers (SOAs), and planar waveguide optical amplifiers (PWOAs). This document defines requirements for accurate and reliable measurements of the noise figure parameters of OAs by means of the electrical spectrum analyser (ESA) method. The noise figure parameters of OAs are defined in IEC 61291-1. This edition includes the following significant technical changes with respect to the previous edition: a) shortening and clarification of the scope in Clause 1; b) update of the normative references in Clause 2; c) deletion of duplicate instructions in 7.2 to measure the time-average input power; d) deletion of unused symbols in 3.3 and addition of new symbol. LIEC 61290-3-2:2026 s’applique aux amplificateurs optiques (OA) disponibles sur le marche, y compris les OA qui utilisent des fibres pompees optiquement, (c’est-a-dire des amplificateurs a fibres optiques (OFA) bases soit sur des fibres dopees aux terres rares, soit sur l’effet Raman), les amplificateurs optiques a semiconducteurs (SOA), ainsi que les amplificateurs optiques a guide d’onde planaire (PWOA). Le present document definit les exigences relatives a des mesures exactes et fiables des parametres du facteur de bruit associes aux OA, par l’intermediaire de la methode de l’analyseur de spectre electrique (ESA). Les parametres du facteur de bruit associe aux OA sont definis dans l’IEC 61291-1. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: a) le domaine d’application a l’Article 1 a ete raccourci et clarifie; b) les references normatives a l’Article 2 ont ete actualisees; c) les instructions en doublon en 7.2, consistant a mesurer la puissance d’entree continue equivalente, ont ete supprimees; d) les symboles non utilises en 3.3 ont ete supprimes et un nouveau symbole a ete ajoute.
