标准摘要
[中文适用范围]： 描述单平衡对缆线在平衡4对缆线系统中的实施规则，该系统的每个导体允许电流为0.75 A。 描述使用ISO/IEC 11801-1:2017组件和缆线来实现和配置符合ISO/IEC 11801-3:2017/AMD1:2021、ISO/IEC 11801-4和ISO/IEC 11801-6。 描述通用单对信道中的链路和组件，符合ISO/IEC 11801-1:2017/AMD1:-。 描述使用应用特定的单对信道补充ISO/IEC 118011:2017/AMD1:-。 描述在使用4对缆线时单对远程供电应用的指导。 描述规划、管理和安装的指南。 [外文原描述]： ISO/IEC TR 11801-9911:2024, which is a Technical Report, a) describes the rules of implementation of balanced single pair as described by ISO/IEC 11801-6:2017/AMD1:202x within a balanced 4- pair cabling system with a current carrying capacity of 0,75 A per conductor; b) describes the use of components and cabling to implement and configure according to ISO/IEC 11801-6:2017/AMD1:202x c) describes links and components for generic single pair channels according to ISO/IEC 11801-1:2017/AMD1:202x. Particular areas of interest are: • remote powering according to IEEE Std 802.3, Clause 104 • loop resistance, max. current • insertion loss • return loss • noise considerations • frequency range requirements (low and high) • length calculation of the SCP-Link-4-pair-cable • number of channels d) describes the use of application specific single pair channels in addition to ISO/IEC 11801:2017/AMD1:202x, 6.6.4 e) describes guidance on single pair remote powering applications when using 4-pair cabling with current carrying capacity specified f) describes guidelines for planning, administration and installation
