本論文提出可應用於光纖與乙太網路之兩款高速連接器設計，分別為SFP+ 28G 1X1連接器與10GBASET-T RJ-45連接器，適合應用於光纖及銅纜兩種不同型態的高速網路傳輸應用。文章首先介紹連接器之基本特性，藉由了解高頻理論來支持連接器的分析方法與設計方向，最後再對本論文所提出之兩款連接器進行討論，其中基本特性包括連接器的組態結構、機械與電氣性能、材料、製作方式及類型等，而高頻理論包含阻抗匹配、時域反射原理、訊號完整度、混模訊號差異、耦合與串音干擾、傳輸延遲等。本論文應用電磁模擬軟體輔助設計，以針對兩款連接器進行阻抗分析調整、傳輸路徑優化、串音干擾防治，並提出改善後連接器結構，使兩款連接器均可滿足機械與電氣特性規範。提出之SFP+ 28G 1X1連接器為可達28 Gbps之小封裝可插拔連接器，較前代提升一倍的傳輸速度，可用於交換機、路由器、伺服器或PON的光網路單元等的設備上。至於10GBASE-T RJ-45則為即將取代原有1000BASE-T規格的新一代高速網路I/O端埠，速度提升10倍達10 Gbps，可相容於Category 6A以上的銅雙絞纜線。此外，本研究運用TRL校正測試治具進行SFP+ 28G 1X1連接器樣品的高頻特性驗證與分析，並提出利用PCB走線交錯來設計適合RJ-45的高速電路佈局與四層板疊構，以及一個評估外殼電磁干擾屏蔽性能的實驗方法。本研究提出的方法可以應用於高速連接器的研發與設計，期能為連接器產業帶來更大效益。

This thesis proposes two high speed connector designs for applications in optical fiber and Ethernet, respectively. First, the basic characteristics of the connectors and high-frequency theory to support those designs and analyses are introduced. The basic characteristics include connector configurations and structures, mechanical and electrical functions, materials, manufacturing methods, and categories. The high-frequency theories cover impedance matching, time-domain reflection, signal integrity, mixed-mode signals, coupling effects, crosstalk, and propagation delay. Those connectors are designed to have good impedance matching, low transmission loss, and minimal crosstalk. The first design, SFP+ 28G 1X1, is the new type of the small form-factor pluggable (SFP) transceiver connector, which has a data rate up to 28 Gbps. The SFP transceiver is generally used in switches, routers, servers, PON optical network units, etc. The second design is the new generation of the RJ-45, which can increase the total transmission speed to 10 Gbps. Both of them are excellent for applications in high speed Ethernet with the former connected to optical fiber for optical line terminal devices and the latter linked to twisted-pair copper lines for Ethernet end users. Besides, this thesis also performs verification by using an SFP+ 28G test fixture based on TRL calibrations for SFP+ 28G 1X1 connector samples, designs a 4-layer PCB for RJ-45 differential pairs, and develops a method to measure the EMI shielding performance of the connector cage. The contents covered in this thesis are useful for connector designs and may be applied to enhance connector markets.
