动态模块.总则和指南

[中文适用范围]： IEC 62343 适用于所有市售光学动态模块和设备。它描述了 IEC 62343 系列涵盖的产品，定义了术语、基本考虑因素和基本方法。本文件的目的是建立动态模块 (DM) 的操作、可靠性和环境特性的统一要求，并在适当的 DM 标准中实施，并为购买者为其特定的选择始终如一的高质量 DM 产品提供帮助。应用程序，以及适当的特定 DM 标准的咨询。本文件涵盖性能模板、性能标准、可靠性鉴定要求、硬件和软件接口以及相关测试方法。由于动态模块集成了光学模块/器件、印刷线路板和软件/固件，因此该系列中开发的标准将模仿适当的现有标准。另一方面，由于“动态模块”是一个相对较新的产品类别，动态模块标准系列将不会受到需求不同的现有做法的限制。与动态模块相关的安全标准主要是光功率考虑因素，IEC TC 76：光辐射安全和激光设备涵盖了这一点。 [外文原描述]： IEC 62343:2017 applies to all commercially available optical dynamic modules and devices. It describes the products covered by the IEC 62343 series, defines terminology, fundamental considerations and basic approaches. The object of this document is to: establish uniform requirements for operation, reliability and environmental properties of dynamic modules (DMs) to be implemented in the appropriate DM standard, and provide assistance to the purchaser in the selection of consistently high-quality DM products for his particular applications, as well as in the consultation of the appropriate specific DM standard(s). This document covers performance templates, performance standards, reliability qualification requirements, hardware and software interfaces and related testing methods. Since a dynamic module integrates an optical module/device, printed wiring board, and software/firmware, the standards developed in the series will mimic appropriate existing standards. On the other hand, since "dynamic module" is a relatively new product category, the dynamic module standards series will not be bounded by the existing practices where requirements differ. The safety standards as related to dynamic modules are mostly optical power considerations, which is covered by IEC TC 76: Optical radiation safety and laser equipment. This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: the inclusion of definitions for the wavelength selective switch.
