摘要
100BaseTX以太网是在住宅、商业和工业环境中使用铜线进行高速数据传输的一种流行方法。通过适当的电路设计和印刷布线板布局,可以使IEEE 802.3 100BaseTX以太网系统符合适用的FCC Part 15 B类辐射发射要求和使用非屏蔽双绞线的欧盟辐射和传导抗扰EMI合规要求。由于硬件和软件的大量现成可用性,在国防/航空航天平台上使用100BaseTX以太网有许多优点,可以快速且经济有效地增加系统能力。当100BaseTX以太网与各种电缆/连接器系统一起使用时,本文提供了确定国防/航空航天设备EMI要求的预期发射和抗扰度的方法。提出了电缆/连接器系统的数据和分析,该系统将允许满足各种国防/航空航天EMI要求。
Selection of cables and connectors for 100BaseTX Ethernet for defense/aerospace environment EMI compliance
100BaseTX Ethernet is a popular method of high-speed data transfer using copper wire in the residential, commercial and industrial environments. Through proper circuit design and printed wiring board layout, IEEE 802.3 100BaseTX Ethernet systems can be made to comply with the applicable FCC Part 15 class B radiated emissions requirements and the European Union's radiated and conducted immunity EMI compliance requirements using unshielded twisted pair wiring. Because of the tremendous off-the-shelf availability of hardware and software, there are many advantages to using 100BaseTX Ethernet on defense/aerospace platforms to quickly and cost effectively increase system capability. This paper provides methods of determining expected emissions and immunity with respect to defense/aerospace equipment EMI requirements when 100BaseTX Ethernet is used with various cable/connector systems. Data and analysis are presented for cable/connector system that will allow various defense/aerospace EMI requirements to be met.
