Abstract :
A simple theory taking into account both source noise and receiver noise contribution to the s.n.r. performance of analogue fibre optic systems is derived and experimentally verified. Experiments indicate that high quality a.m.-v.s.b. video transmission (s.n.r. > 60 dB) is not feasible with state-of-the-art gain-guided laser diodes.
