本論文提出將主動光纜技術應用於傳輸虛擬實境的高清影像。我們以HTC VIVE系統為測試載具，並將VIVE系統的HDMI、USB及功率傳輸線組整合為一複合式纜線。其中，HDMI高頻訊號透過光纖以光訊號傳輸，我們將輸入的HDMI數位訊號轉換成類比訊號再驅動面射型雷射經由光纖傳抵接收端，接收端的類比訊號再經由光檢器收集並將訊號再轉換成數位訊號輸出。另一方面，USB低頻訊號及功率之傳輸則以傳統銅線完成。
我們主要的工作會從分析VIVE VR原有系統架構開始，再規劃VR AOC架構，並設計AOC結構、高速電路板、外殼機構、複合式纜線。最後完成VR AOC組裝，並進行影音傳輸及VR設備測試。

In this paper, active optical cable (AOC) is proposed for transmitting high density images of a virtual Reality (VR) system. We tested the AOC technology using HTC VIVE system. The HDMI cable, USB cable, and power delivery cable of the VIVE system were integrated into a single hybrid cable. However, in the hybrid cable, the transmission of HDMI data is now accomplished through optical fibers. At the transmitting end, the high frequency HDMI digital signals were converted into analog optical signals using a VCSEL array. The optical signals through fibers were collected by a photodetector array and were converted back to digital signal output at the receiving end. On the other hand, the USB low speed signals and power were delivered to the receiver end using copper wires.
The fabricating of the VR AOC was started by analyzing the VIVE VR structure. Then the new VR AOC architecture was defined, including the designs of high-speed printed circuit board, cases, and hybrid cable. After the assembly of the VR AOC, audio and video transmission and VR game testing were tested.
