EN IEC 61291-1:2018

Optical amplifiers - Part 1: Generic specification

IEC 61291-1:2018 applies to all commercially available optical amplifiers (OAs) and optically amplified assemblies. It applies to OAs using optically pumped fibres (OFAs based either on rare-earth doped fibres or on the Raman effect), semiconductors (SOAs), and waveguides (POWAs). The object of this document is - to establish uniform requirements for transmission, operation, reliability and environmental properties of OAs, and - to provide assistance to the purchaser in the selection of consistently high-quality OA products for his particular applications. Parameters specified for OAs are those characterizing the transmission, operation, reliability and environmental properties of the OA seen as a "black box" from a general point of view. In the sectional and detail specifications a subset of these parameters will be specified according to the type and application of the particular OA device or assembly. This fourth edition cancels and replaces the third edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - terms have been added for parameters from IEC 61290-4-3 and IEC 61290-10-5; - Clause 4 Classification has been removed, since this system is judged to be unused; - the definition of polarization mode dispersion (PMD) has been simplified. Keywords: optical amplifiers (OAs)

Lichtwellenleiter-Verstärker - Teil 1: Fachgrundspezifikation

Amplificateurs optiques - Partie 1: Spécification générique

IEC 61291-1:2018 s’applique à tous les amplificateurs optiques (OA) et systèmes à amplification optique, disponibles sur le marché. Elle s’applique aux OA utilisant des fibres pompées optiquement (OFA basés sur des fibres dopées aux terres rares ou sur l’effet Raman), des semiconducteurs (SOA) et des guides d’ondes (POWA). Le présent document a pour objet - d’établir des exigences uniformes pour la transmission, le fonctionnement, la fiabilité et les propriétés liées à l'environnement des OA, et - d’aider les acheteurs à sélectionner des produits OA de qualité élevée et constante pour leurs applications. Les paramètres spécifiés pour un OA sont ceux qui caractérisent les propriétés de transmission, de fonctionnement, de fiabilité et d’environnement de l’OA, considéré globalement comme une "boîte noire". Dans les spécifications intermédiaires et particulières, un sous-ensemble de ces paramètres sera spécifié d’après le type et l’application d’un module OA ou d’un système d’OA particulier. Cette quatrième édition annule et remplace la troisième édition parue en 2012. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - des termes ont été ajoutés pour des paramètres de l'IEC 61290-4-3 et de l'IEC 61290-10-5; - la classification de l'Article 4 a été retirée car elle n'est pas utilisée; - la définition de la dispersion du mode de polarisation a été simplifiée. Mots clés: amplificateurs optiques (OA)

Optični ojačevalniki - 1. del: Splošna specifikacija (IEC 61291-1:2018)

Ta del standarda IEC 61291 se uporablja za vse komercialno dostopne optične ojačevalnike (OA) in optično ojačane sestave. Velja za optične ojačevalnike z optično črpanimi vlakni (OFA, ki temeljijo na dopiranih vlaknih redke zemljine ali Ramanovem efektu), polprevodniki (SOA) in valovodi (POWA).
Cilj tega dokumenta je
– določiti enotne zahteve za prenos, delovanje, zanesljivost in okoljske lastnosti optičnih ojačevalnikov in
– zagotoviti pomoč kupcu pri izbiri visokokakovostnih optičnih ojačevalnikov, ki bodo ustrezali njegovi uporabi.
Parametri, ki so določeni za optične ojačevalnike, označujejo prenos, delovanje, zanesljivost in okoljske lastnosti optičnega ojačevalnika, ki je na splošno videti kot »črna skrinjica«. V področnih in podrobnih specifikacijah bo določena podmnožica teh parametrov glede na tip in uporabo posameznega optičnega ojačevalnika ali sestava.

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 w
