本論文的目的為製造主動光纜(Active optical cables)於4×10Gb/s QSFP+之上，並且可運用於雲端伺服器中心之中，其中在主動光纜上包含了傳輸模組、混和纜線和接收模組三個部分。在光致電與電致光轉換介面上利用了被動對準的方式將×4 陣列的45°研磨光纖鏡面與×4陣列VCSEL或光檢器相互組合，製作傳輸模組和接收模組。
除此之外，在高頻印刷電路板上使用差分對結構將高速電訊號從輸入端輸入VCSEL驅動IC中，驅動傳輸模組進行傳輸；或是將光訊號由接收模組輸入限伏放大器中並由輸出端輸出。因此為了驗證高速訊號的完整性，我們將會在製造元件之前利用高頻驗證評估版(Evaluation Boards，EVB)進行高頻測試。最後，我們在10Gb/s誤碼率量測系統下完成製造元件的高頻量測。

The purpose of this dissertation is to fabricate 4×10Gb/s QSFP+ Active optical cables(AOCs) for applications such as data center. The AOC is consisted with optical transmitted modules, hybrid cable, and optical receiving modules. The E-O and O-E interfaces of the transmitting module and the receiving module were obtained by passively-aligned ×4 45°fiber mirrors to ×4 VCSEL array and photodiode array.
In addition, differential pair structures on PCB were used to carry the high-speed electrical signals from the input node to the VCSEL driver of the transmitting module and from the limiting amplifier of the receiving module to the output node. The high-speed performance of the PCB was test by using evaluation boards before fabricating the optical modules.Finally, the eye diagram of the fabricated devices was tested using 10Gb/s bit error rate system.
