本論文提出三款不同規格的高速I/O連接器設計，第一款QSFP+2X1連接器為一款具有雙層四通道架構之小封裝熱插拔接收器，在單位機箱空間下可以達到原QSFP+連接器的兩倍傳輸容量，可應用於高速網路交換器、路由器與雲端伺服器等設備上，其數據傳輸速率可達單通道12Gbps。第二款nQSFP+1X1連接器為新一代的QSFP+連接器，其數據傳輸速率從單通道12Gbps提升至25Gbps。第三款為Mini SAS HD連接器，此款連接器常用於磁碟陣列伺服器中，數據傳輸速率最高可達單通道12Gbps。本研究針對上述三款高速I/O連接器分析其結構對阻抗之影響，其中同時考量機械特性與電氣特性，來調整連接器端子與塑膠的結構，以設計符合規範要求之高速連接器。此外，亦進行時域與頻域量測驗證，其中時域量測包含差模阻抗和傳輸偏移量，頻域量測包含差模反射係數、差模傳輸係數和串音干擾，並應用電路模擬軟體分析以獲得連接器的傳輸通道特性。本論文所提出之設計概念、驗證流程和分析方法可應用於高速連接器的設計與分析。

This thesis propose three kinds of high speed I/O connectors design. The first design is two-layered quad small form-factor pluggable transceiver (QSFP) connector which can offer 2 times the data rate of original QSFP+ in the same space of the chassis with four-channel package and it supports speeds up to 12Gbps per channel. The SFP transceiver can be used in switches, router, servers, etc.. The second design is nQSFP+1X1 connector which is the next generation SFP system, with upgrading the speeds from 12Gbps to 25Gbps per channel. The third design is about Mini SAS HD connector which is commonly used in the RAIDs server(Redundant Array of Individual Disk Server) with the data rate up to 12Gbps.In this thesis, electromagnetic simulation software is applied to analyze the effects of the structure on the proposed connectors. Both mechanical and electrical properties were taken into account to adjust the structure of the connector and make the proposed connectors fulfill their own specification. In addition, the verification performed in time-domain measurements and frequency-domain measurements. The time-domain measurements include time-domain reflection impedance and propagation delay and the differential reflection coefficient, differential transmission coefficient and the crosstalk can be obtained in the frequency-domain measurements. Finally, the eye-diagram analyses can be acquired from the channel simulation. The design principles and the verification methods applied to design of high speed I/O connectors will be presented in the thesis.
