Annotation of standard text IEC 61290-4-1-ed.2.0 :
IEC 61290-4-1:2016 applies to optical amplifiers (OAs) using active fibres (optical fibre amplifiers (OFAs)) containing rare-earth dopants including erbium-doped fibre amplifiers (EDFAs) and optically amplified elementary sub-systems. These amplifiers are commercially available and widely deployed in service provider networks. The object of document is to provide the general background for OFA transients and related parameters, and to describe a standard test method for accurate and reliable measurement of the following transient parameters: - channel addition or removal transient gain overshoot and transient net gain overshoot; - channel addition or removal transient gain undershoot and transient net gain undershoot; - channel addition or removal gain offset; - channel addition or removal transient gain response time constant (settling time). This second edition cancels and replaces the first edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - extended the applicability from only EDFAs to all OFAs; - updated definitions for consistency with other documents in the IEC 61290-4 series. Keywords: optical amplifiers (OAs), optical fibre amplifiers (OFAs), rare-earth dopants, erbium-doped fibre amplifiers LIEC 61290-4-1:2016 sapplique aux amplificateurs optiques (OA) utilisant des fibres actives (amplificateurs a fibres optiques (OFA)), dopees aux terres rares. Elle concerne egalement les amplificateurs a fibre dopee a lerbium (EDFA) et les sous-systemes elementaires a amplification optique. Ces amplificateurs sont disponibles sur le marche et sont largement deployes dans les reseaux de prestataires de service. La presente partie de lIEC 61290-4 a pour objet de fournir le contexte general pour les transitoires dOFA et les parametres associes, et de decrire une methode dessai normalisee de mesure exacte et fiable des parametres transitoires suivants: - depassement positif du gain transitoire lors de lajout ou de la suppression de canaux et depassement positif du gain net transitoire; - depassement negatif du gain transitoire lors de lajout ou de la suppression de canaux et depassement negatif du gain net transitoire; - decalage de gain lors de lajout ou de la suppression de canaux; - constante de temps de reponse du gain transitoire lors de lajout ou de la suppression de canaux (temps de stabilisation). Cette deuxieme edition annule et remplace la premiere edition parue en 2011. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - extension de lapplication des seuls EDFA a lensemble des OFA; - mise a jour des definitions dans un objectif de coherence avec les autres documents de la serie IEC 61290-4. Mots cles: amplificateurs optiques (OA), amplificateurs a fibres optiques (OFA), dopees aux terres rares, des amplificateurs a fibre dopee a lerbium
