摘要

近年來由於無線通訊需求快速的成長，使得微波光纖通訊系統受到高度的重視，本論文的主旨在開發新穎光電模組於微波光纖通訊系統，包括研究以相位調變器為基礎之微波頻率倍增模組、使用微波頻率倍增模組所架設之多重服務接取網路。這些新穎光電模組已詳盡的實驗分析與驗證，並且在以微波頻率倍增模組為基礎之多重服務之接取網路中，結合了有線電視系統和微波光纖通訊系統，同時傳送有線電視訊號從Channel 78∼Channel 115（547.25 MHz∼739.25 MHz）以及從7.5 GHz全光倍增頻率至15 GHz的200 Mbps之微波訊號，於25公里的單模光纖傳輸中，有線電視和微波光纖通訊的品質均符合規範，研究成果將有助於微波光纖通訊系統之發展。

In recent years, radio-over-fiber communication systems have received huge attention because of the fast growth of the demand of wireless communication. In this dissertation, we develop a novel electro-optical module for radio-over-fiber communication systems, including a microwave frequency multiplier module and a multi-service access network based on the microwave frequency multiplier module. The novel electro-optical module has been carefully analyzed and verified. The multi-service access network based on the microwave frequency multiplier module includes both cable television systems and radio-over-fiber systems communication. Furthermore, we simultaneously transmit the cable television signals from channel 78 to channel 115（547.25 MHz∼739.25 MHz）and the microwave signal with 200 Mbps elevated the frequency from 7.5 GHz to 15 GHz based on the microwave frequency multiplier module. The qualities of cable television and radio-over-fiber communication both conform to the criteria after transmitting over 25-kilometer single-mode-fiber. The results of the research will be contributive to the evolution of radio-over-fiber communication systems.
