动态模块.通用规范

[中文适用范围]： 本文件适用于所有市售的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： 为动态模块（DMs）的操作、可靠性和环境特性建立统一要求，以便在适当的DM标准中实施，并为购买者在选择适合其特定应用的高质量DM产品以及咨询适当的特定DM标准时提供帮助。 本文件涵盖性能模板、性能标准、可靠性资格要求、硬件和软件接口及相关测试方法。 由于动态模块集成了光学模块/设备、印刷线路板和软件/固件，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受现有做法的约束，其中要求有所不同。 与动态模块相关的安全标准主要是光功率考虑，由IEC 60825系列涵盖（见第6条）。 [外文原描述]： IEC 62343:2023 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 their 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 bound by the existing practices where requirements differ.The safety standards as related to dynamic modules are mostly optical power considerations, which is covered by the IEC 60825 series (see Clause 6). This third edition cancels and replaces the second edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - addition of terms and definitions for optical multicast switches (3.8); - revision of Clause 4, listing the requirements for standards in the IEC 62343 series; - addition of Clause 6 (Safety requirements).
