Fiber-optic access is a hot spot in recent development of Direct Broadcast Satellite（DBS） covering technology and the development of the optical transmitter and receiver for the transmission of the broadband DBS TV signals from new generation Ka-band satellites has currently become an important research question.On the basis of the analysis of the DBS signals and the principle of the optical receiver and in light of the application features of fiber-optic broadband access networks

a 3 GHz analog optical receiver with fairly high sensibility and large dynamic range has been designed and developed for the optical broadband satellite TV signals.
