IEC 62343:2023 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 62343:2023适用于所有商用光学动态模块和器件。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，并在适当的DM标准中实施，以及 -协助买方为其特定应用选择始终如一的高质量DM产品，以及咨询适当的特定DM标准。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/设备、印刷电路板和软件/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受要求不同的现有实践的约束。与动态模块相关的安全标准主要是光功率考虑因素，IEC 60825系列涵盖了这一点（参见第6条）。这第三版取消并取代了2017年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: -增加光多播交换机的术语和定义(3.8)； -修订第4条，列出IEC 62343系列标准的要求； -加入第6条（安全规定）。

IEC 62343:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

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).
