标准摘要
[中文适用范围]： IEC 62783-2:2025 规定了在数字通信系统中使用的双轴（twinax）电缆的定义和要求。本文件适用于室内使用的双轴电缆。这些规范旨在支持ISO/IEC/IEEE 8802-3标准中关于双轴电缆物理层（PHY）的以太网双轴链路段规范。本文件给出了单根双轴元件以及同一护套内多个双轴元件（即“双轴电缆”）的要求和传输特性。本版取消并替代了2019年发布的首版。本版为技术修订版。与上一版相比，本版包含以下重大技术更改：a) 根据IEC 62783-1:2023中修订后的通用双轴电缆要求进行更新；b) 根据近期添加到ISO/IEC/IEEE 8802-3以太网物理接口中的新双轴链路段规范进行更新。 [外文原描述]： IEC 62783-2:2025 specifies the definitions and requirements of twin-axial (twinax) cables used in digital communication systems. This document covers twinax cable intended to be used indoors. The specifications are intended to support the twinax link segment specifications of the ISO/IEC/IEEE 8802-3 Ethernet over twinax physical layer (PHY) specifications. This document gives requirements and transmission characteristics for a single twinax element as well as for multiple twinax elements within the same sheath, i.e. "twinax cable". This second edition cancels and replaces the first edition published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) updating according to the revised generic twinax cable requirements given in IEC 62783 1:2023; b) updating according to new twinax link segment specifications recently added to ISO/IEC/IEEE 8802-3 Ethernet physical interfaces.
