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 of optical amplifiers EDFA cost competitive FTTC systems will be realized 1,2. The strategy for the distribution of HDTV-channels is not so clear today, but in any case, digital transmission will yield the highest quality 3. In this paper we demonstrate the feasibility of flexible TVHDTV-distribution using simultaneous analogue AM and digital PCM transmission over optical amplifiers without any mutual quality degradation.
