IEC？62783-2:20 19涵盖室内电缆，并规定了数字通信系统中使用的双轴电缆的定义和要求。本文件是一个系列规范，给出了IEEE中使用的双轴电缆的附加要求？标准802.3以太网物理接口。 本文件给出了单个双轴元件以及同一护套内的多个双轴元件（即“双轴电缆”）的要求和传输特性。本国际标准将与IEC一起使用？62783-1:2019.

IEC？62783-2:2019 covers indoor cables and specifies the definitions and requirements of twin-axial cables used in digital communication systems. This document, which is a family specification, gives additional requirements for twinax cables for use in IEEE？Std 802.3 Ethernet physical interfaces.
This document gives requirements and transmission characteristics for single twinax elements as well as for multiple twinax elements within the same sheath, i.e. "twinax cable". This International Standard is to be used in conjunction with IEC？62783-1:2019.
