摘要：

A single model for analogue fibre-optic links is presented that is applicable using either direct or external modulation. The impact of device slope efficiency and effective resistance on the link gain and noise figure is explored, and it is found that both may be improved significantly. The gain improvements may be implemented at the source or detector end of the link; the noise figure is more effectively improved at the source end. The influence on gain and noise figure of average optical power and modulator sensitivity is also examined.
