非屏蔽布线系统是否能满足电磁兼容的要求?关于这一问题行家们是仁者见仁,智者见智,各抒所见,从未得出一个统一的结论。目前,国际标准化组织和欧洲标准化组织也正在进行关于UTP系统在强干扰环境下能否满足高速数据应用的研究,但这些研究仅仅是理论上的,很难定量。另外这些研究手段的片面性还在于测试中采用的干扰源并非生活中常见的一些干扰源,例如:高频发射器、电动马达、甚至萤光灯等。 为了测出UTP系统对普通EMI干扰源的敏感程度,我们将IEEE802.3u100BASE-TX1以太网暴露在各种干扰源下,用通用网络分析程序进行测试,下面
Unscreened wiring system is able to meet the electromagnetic compatibility requirements? Experts on this issue is benevolent benevolence, wisdom see wisdom, express their views, never come to a unified conclusion. At present, the International Organization for Standardization (ISO) and the European Organization for Standardization (OAS) are also conducting research on whether UTP systems can meet the requirements of high-speed data applications in a strong interference environment. However, these studies are only theoretical and difficult to quantify. In addition, the one-sidedness of these research methods lies in that the sources of interference used in the test are not common sources of interference in life, such as high frequency transmitters, electric motors and even fluorescent lamps. In order to measure the sensitivity of the UTP system to ordinary EMI sources, we exposed the IEEE802.3u100BASE-TX1 Ethernet to various interference sources and tested them with a generic network analysis program. The following
