数字通信用多芯和对称对/四芯电缆 第12部分：传输特性高达 600 MHz 的对称单对电缆 工作区布线 分规范

[中文适用范围]： IEC 61156 的这一部分描述了用于办公室、家庭和工业应用中通过单对双绞线进行 1 Gbit/s 传输的电缆。现有应用的一个例子是 1000BASE-T1；参见 ISO/IEC TR 11801-9906。传输特性 [外文原描述]： IEC 61156-12:2021 describes cables intended to be used for transmission of 1 Gbit/s over a single twisted pair for office, home and industrial application. An example of an existing application is 1000BASE-T1; see ISO/IEC TR 11801-9906. The transmission characteristics of these cables are specified up to a frequency of 600 MHz and at a temperature of 20 °C. The cable type recognised is intended to be used for the work area wiring of shielded channels with a nominal length of 40 m. Possible designs are U/FTP, X/UTP and X/FTP, where X stands for F, S or SF. The cables covered by this document are intended to operate with voltages and currents normally encountered in communication systems. While these cables are not intended to be used in conjunction with low impedance sources, e.g. the electric power supplies of public utility mains, they are intended to be used to support the delivery of low voltage remote powering applications.
