摘要
针对10BASE-T局域网的非屏蔽双绞线的电磁信息泄漏的现状,在分析非屏蔽双绞线的传输机理的基础上提出了计算传输信号的耦合模型,理论上求得线缆两端和沿线的电压电流分布,从而给出了非屏蔽双绞线的差模辐射和共模辐射计算方法,并将理论结果与实测结果对比验证,其一致性证明了该模型和计算方法的可行性。
The transmission mechanism of unshielded twisted-pair used in 10BASE-T LAN is analyzed,According to its status of the leakage of electromagnetism information,the coupling model which could educe the voltage and current distributing in theory is proposed. And the method of calculating common-mode and differential-mode of radiation field is acquired. The academic results are validated by the practical results and the consistency proves the model and the method are feasible.
