| Abstract: | A fundamental limit on the number of channels in an SCM lightwave CATV system is derived by considering an idealised link consisting of a shot-noise-limited receiver and a laser transmitter with a linear light/current characteristic. For VSB-AM TV, the limit is only 50 channels per milliwatt of received optical power.< |
