Abstract :
The influence of the source-drive duty factor on the performance of a digital fibre-optic communication system is explored. The system considered utilises an l.e.d. source and either a p¿i¿n or avalanche photodetector. It is shown that, for a fibre with known dispersion, an optimum duty factor exists which offers significant s.n.r. advantages over a system with impulsive excitation.
