摘要
电话网线在传送信号的同时会在沿线产生电磁发射从而造成信息泄漏,为保护信息安全,除采用分区隔离、线缆屏蔽、屏蔽体接地等措施以外,接线端子的屏蔽尤其重要,文章重点介绍了一些有效的接线端子屏蔽方法,运用这些方法可获得比较理想的电话网线电磁泄漏防护效果。
Telephone network line also generate EM emission when it transmits sound and chart signal . It will lead to information leakage. So we have to protect from information leakage. This paper describe insulation for red\black section and characteristic of cable shielded , analyze principle and measure of connection port shielded.
