在結構化佈線系統的領域中，消除RJ45連接器串音的干擾是一件很重要的技術課題，由於串音干擾會影響通訊系統的信號傳輸品質，如何消除串音干擾仍然是目前的重要議題。已知有很多種藉由消除串音干擾來提升傳輸系統的傳輸效能，消除串音干擾對於使用寬頻通訊系統的網路結構化佈線系統的RJ45連接器也是非常重要的。本論文著重於研究消除串音干擾將會透過串音原理分析、電磁模擬軟體來完成目前國際規範所定義的最高傳輸等級之RJ45連接器至頻率2GHz，實際量測結果作為分析討論的驗證，量測數據圖示與模擬數據相當符合，充分證明理論分析的有效性。本論文的研究資料實際上足作為在下一世代網路通訊降低串音干擾的參考資料。

Crosstalk reduction issue is one of the most important issues of structure cabling systems. Poor crosstalk performance will highly affect the quality of signal transmission of communication systems, therefore the study of crosstalk reduction is still an important issue currently. Practically, there are a lot of methods of reducing crosstalk to improve transmission performance in communication systems. For RJ45 connector of network structure cabling systems, crosstalk issue is the most important problem since the transmission system is broadband. In this thesis, the crosstalk phenomenon is analyzed and the crosstalk reduction will be demonstrated in high speed digital systems. Simulation tool, finite element method within the simulation tool Cadence Power SI and measurement system for 500MHz in the well known international standard ANSI/TIA-568-C.2 and ANSI/TIA-1183 is used and performed. The measured data of crosstalk in this thesis may become the useful reference for near future development. The next generation network category is now being well known as Category 8 which will be published in the beginning of 2016.
