局域网非屏蔽双绞线的电磁泄漏测试分析

Analysis of Electromagnetic Leakage on Transmitting of Unshielded Twisted-Pair Used in LAN

针对局域网非屏蔽双绞线电磁信息泄漏的现状,分析了非屏蔽双绞线的传输机理,给出了计算传输信号的耦合模型;分析了非屏蔽双绞线电磁泄漏的测试结果,对处理非屏蔽双绞线的电磁兼容性问题具有参考价值。

This paper analyzes the transmission mechanism of unshielded twisted-pair according to the status of the leakage of electromagnetism information of UTP used in LAN, consequently educes the coupling model. This test is a typical EMC experiment item. It may provide a reference for dealing with the EMC problem of UTP.
