光纤放大器.第5-2部分:合格评定规范.光纤放大器可靠性合格评定

[中文适用范围]： IEC 61291 的这一部分适用于地面应用的光放大器 (OA) 和光放大基本子系统，使用含有稀土掺杂剂的有源光纤（光纤放大器 (OFA)），这些光纤是市售的。本文档使用黑盒方法。采用黑盒方法是为了提供独立于 OA 实施细节的产品规范。出于可靠性鉴定的目的，需要一些有关内部组件的信息；这些内部部件本身被视为黑匣子。本文件结合此类内部黑匣子的可靠性给出了OA可靠性评估的要求。本文件的目的是规定可靠性鉴定测试的最低清单、测试过程中的失效准则和可靠性预测的要求，并给出相关规范性参考，以建立OFA设备及其子系统可靠性评估的标准方法。系统，以最大限度地降低风险并促进产品开发和可靠性鉴定。 [外文原描述]： 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.
