Optical amplifiers - Part 5-2: Qualification specifications - Reliability qualification for optical fibre amplifiers

Edition date: 2017-01-25
In Force
Available languages: English, French
Summary: IEC 61291-5-2:2017 applies to optical amplifiers (OAs) and optically amplified, elementary sub-systems for terrestrial applications, using active fibres (optical fibre amplifiers (OFAs)) containing rare-earth dopants, which are commercially available. The black box approach is used in this document. The black box approach is adopted in order to give product specifications which are independent of OA implementation details. For reliability qualification purposes, some information about the internal components is needed; these internal parts are themselves treated as black boxes. This document gives requirements for the evaluation of OA reliability by combining the reliability of such internal black boxes. The object of this document is to specify the minimum list of reliability qualification tests, requirements on failure criteria during testing and on reliability predictions, and give the relevant normative references to establish a standard method for the assessment of the reliability of OFA devices and sub-systems in order to minimize risks and to promote product development and reliability qualification. This second edition cancels and replaces the first edition published in 2002. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) removal of the contents on the relating quality management system from scope, terms and definitions, and the reliability requirements;
b) moving fit-rate calculation to Annex B (informative);
c) change of requirements for shock test;
d) amendment of abbreviations related to changes a) and b).
The contents of the corrigendum of May 2019 have been included in this copy.

IEC 61291-5-2: 2017 s’applique aux amplificateurs optiques (AO) et aux sous‑systèmes élémentaires amplifiés optiquement pour des applications terrestres, utilisant des fibres actives (amplificateurs à fibres optiques, AFO), qui contiennent des dopants de terres rares, disponibles sur le marché. L’approche de boîte noire est utilisée dans le présent document. L’approche de boîte noire est adoptée afin de fournir des spécifications de produits qui sont indépendantes des détails de mise en service des AO. Pour les besoins de qualification de fiabilité, certaines informations sur les composants internes sont nécessaires; ces parties internes sont elles-mêmes traitées en tant que boîtes noires. Le présent document fournit des exigences relatives à l’évaluation de la fiabilité des AO en combinant la fiabilité de telles boîtes noires internes. Le présent document a pour objet de fournir la liste minimale des essais de qualification de fiabilité, des exigences en matière de critères de défaillance pendant les essais et de prévisions de fiabilité, et de donner des références normatives pertinentes afin d’établir une méthode normalisée pour l'évaluation de la fiabilité des modules et des sous-systèmes AFO afin de réduire le plus possible les risques et d’avancer le développement du produit et la qualification de la fiabilité. Cette deuxième édition annule et remplace la première édition parue en 2002. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) le contenu sur le système de management de la qualité a été retiré du domaine d’application, des termes et définitions et des exigences de fiabilité;
b) le calcul du taux de défaillance dans le temps (FIT) a été déplacé à l’Annexe B (informative);
c) les exigences relatives aux essais de chocs ont été modifiées;
d) les abréviations ont été modifiées en fonction des modifications a) et b).
