| Abstract: | In this paper, fundamental limit and main technology for multichannel TV repeating transmission of microwave subcarrier-multiplexing in optical fiber are shown. The limit on number of channels in repeating system for TV PAL-D system and the optimum using frequency band are analysed. Requirements for optical system result from dispersion and attenuation of monomode fiber are discussed. The plan of system unit composed of three levels, which are lightwave level, microwave level and TV level, is described. Some experiments are made for repeating system unit. |
