Performance Analysis on Distribution of M-QAM HDTV Signals over FTTF Network
Distribution of 40 channel M-QAM HDTV signals in today’s CATV fiber-to-the feeder (FTTF) network is investigated. System performance is analyzed by considering receiver noises, intermodulation distortion and clipping noise caused by laser, and nonlinear distortion generated by fiber dispersion. For the specified bit-error-rate (BER), the maximum fiber span limited by the fiber dispersion can be derived. system. At the headend, the N-channel M-QAM HDTV signals are subcarrier-multiplexed and converted to optical signal by modulating the intensity of a 1.55pm laser diode, then transmitted through the fiber to the feeder. At the feeder, the optical signal is converted back to the electrical signal by an optical receiver and then distributed via coaxial cables to the subscribers. 111. ANALYSIS
