摘要

近年來，由於無線通訊迅速的發展及家用網路高頻寬整合服務的需求，使得混合式光纖微波通訊系統受到高度的重視，因此我們提出一個同時傳輸無線訊號及有線訊號的傳輸系統，來達到提供多重服務的應用。
　　在本篇論文中，我們提出極化再調變技術於混合式光纖有線電視/光纖微波通訊系統，證明單一光載波以強度/極化方式同時傳輸有線電視與微波射頻訊號之可行性。架構中，使用單一波長之雷射以直接調變方式載入有線電視訊號，同時應用波長再調變技術結合極化調變方式，將無線訊號調變於載波極化上，成功以單一波長雷射同時載送兩種不同之訊號，並於一芯光纖中傳輸。藉由此成果，混合式的傳輸系統不僅滿足了有線電視/高品質無線訊號的要求，更可進一步達到「寬頻整合服務」的功能。

In recent years, radio-over-fiber (ROF) communication develop quickly and home network require the high bandwidth. This study proposed a hybrid lightwave transmission system can transmit CATV signal and radio signal simultaneously to achieve multi-service.
A hybrid cable television/radio-over-fiber (ROF) transport system with direction modulation of cable television signals and the polarization modulation of ROF signals is proposed and experimentally demonstrated .When a multi-carrier cable television signal in the optical amplitude domain and an ROF signal in the optical polarization domain
are modulated, a single optical wavelength can serve these two signal applications simultaneously. This hybrid transport system not only satisfied the cable television
requirements, but also satisfied the demand for high-quality ROF transmission over a 20-km single-mode fiber.
