光纤互连器件和无源组件 - 光纤波分复用器件 - 第1部分：通用规范

[中文适用范围]： IEC 62074-1:2025适用于光纤波分复用（WDM）器件。这些器件具有以下一般特征：- 它们是无源器件，内部不包含任何光电或其他转换元件；不过，它们可以仅通过温度控制来稳定器件特性；它们排除任何光开关功能；- 它们具有三个或更多端口，用于输入、输出或同时用于输入和输出光功率，并根据波长以预定方式在这些端口之间分配光功率；- 端口为光纤或光纤连接器。本文件规定了以下统一要求：- 光学、机械和环境特性。本第三版取消并替代了2014年发布的第二版。本版属于技术修订版。与前一版相比，本版包括以下重大技术变更：a) 与IEC TS 62627-09的术语和定义进行协调；b) 第4章中简化了分类、文档和标准化系统，并将接口样式移至附录H。 [外文原描述]： IEC 62074-1: 2025 applies to fibre optic wavelength division multiplexing (WDM) devices. These have all of the following general features: - they are passive, in that they contain no optoelectronic or other transducing elements; however they can use temperature control only to stabilize the device characteristics; they exclude any optical switching functions; - they have three or more ports for either the entry or exit of optical power, or both, and share optical power among these ports in a predetermined fashion depending on the wavelength; - the ports are optical fibres, or optical fibre connectors. This document establishes uniform requirements for the following: - optical, mechanical and environmental properties. This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) harmonization of terms and definitions with IEC TS 62627-09; b) simplified classification, documentation and standardization system in Clause 4, and moving interface style to Annex H.
