摘要: Abstract : Analogue FDM transmission of AM-VSB TV-channels over optical fibres is used today to upgrade existing copper-based CATV networks. With the aid amplifiers (EDFA) cost competitive FTTC systems will be realized /1,2/. The strategy for distribution HDTV-channels not so clear today, but in any case, digital yield highest quality /3/. In this paper we demonstrate feasibility flexible TV/HDTV-distribution using simultaneous analogue AM and PCM without mutual degradation.
