碩士 === 國立交通大學 === 光電工程系所 === 92 === For future wireless systems it will be an aim to supply broadband access service to a large number of subscribers. Hybrid fiber-radio access technology operating at microwave frequencies with widespread optical fiber feeding is an attractive solution for the future broadband services. In this thesis, a novel WDM fiber-radio network by dynamic wavelength allocation and upstream injection-locked Fabry-Perot laser scheme is presented and experimentally confirmed. The directly modulated injection mode-locked FP-LD that replaces the relative high cost laser source or external optical modulator is used to transmit radio signals in a low-cost regime for acceptance of subscribers. The dynamic structure can provide a simple and efficient method to solve the burst transmission load problems. The architecture based on these techniques can provide the robust, flexible and cost-effective characteristics for large radio terminals.
