摘要
近幾年來，由於無線通訊與有線網際網路的蓬勃發展，人們對於訊號品質、速度與傳送距離等要求也愈來愈高，使用光纖傳遞訊號有低損失、高傳輸容量與保密性高等優點，因此使得光纖通訊成為了無線通訊與網際網路發展的關鍵技術。為了實現這些目標，透過光纖來傳輸微波信號的微波光電 (Radio over fiber, RoF) 系統，與解決網際網路最後一哩 (Last mile) 問題的光纖到家 (Fiber to the home, FTTH) 技術逐漸成為世界各國熱門的研究及發展目標。
本篇論文先以理論分析如何透過一個Single drive Mach-Zehnder調變器來產生光載波抑制與分離(Optical carrier suppression and separation, OCSS)之訊號，再以VPItrassmissionMaker 5.2光通訊軟體模擬實驗之環境，透過模擬之方法，先驗證使用Mach-Zehnder調變器來產生OCSS訊號的正確性，並利用OCSS技術實現基頻雙向傳輸系統，之後再將其系統結構改變，透過光拍頻 (Optical beating) 方式產生光微波信號 (Optical mm-wave) ，實現出混合式微波/基頻雙向傳輸系統。經由VPItrassmissionMaker 5.2模擬完成後，我們再以實驗的方式將基頻雙向傳輸系統、混合式微波/基頻雙向傳輸系統 (Rof and FTTH system) 呈現出來，透過25公里之單模光纖傳送並解調。此混合式多功能之光存取網路，能同時提供網際、電話與電視網路 (Triple play) 使用，也可作為微波信號基地台之間聯繫的網路，實驗的成果，將有助於未來無線通訊與網際網路的發展。
