动态模块.第2部分:可靠性鉴定

[中文适用范围]： IEC 62343 的这一部分适用于市售的动态模块和设备 (DM)。例如可调谐色散补偿器、波长选择开关和光通道监视器。光放大器不包含在此列表@中，但在 IEC 61291-5-2 中进行处理。出于可靠性鉴定目的@需要一些有关内部组件@零件和互连的信息；这些内部部件被视为黑匣子。本标准结合此类内部黑匣子的可靠性给出了DM可靠性评估的要求。该标准的目标如下： 规定 DM 可靠性鉴定的要求；给出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@并给出相关的规范性参考。 [外文原描述]： IEC 62343-2:2014 applies to dynamic modules and devices (DMs) which are commercially available. Examples are tuneable chromatic dispersion compensators, wavelength selective switches and optical channel monitors. Optical amplifiers are not included in this list, but are treated in IEC 61291-5-2. For reliability qualification purposes, some information about the internal components, parts and interconnections is needed; these internal parts are treated as black boxes. This standard gives requirements for the evaluation of DM reliability by combining the reliability of such internal black boxes. The objectives of this standard are the following: - to specify the requirements for the reliability qualification of DMs; - to give the minimum list of reliability qualification tests, requirements on failure criteria during testing and on reliability predictions, and give the relevant normative references. This second edition cancels and replaces the first edition published in 2011 and constitutes a technical revision. The main change with respect to the previous edition is the addition of Annex A (informative), Reliability test items and their conditions. Keywords: dynamic modules and devices (DMs), tuneable chromatic dispersion compensators, wavelength selective switches, optical channel monitors
