Title :
Electrical predistortion to compensate for combined effect of laser chirp and fibre dispersion
Author :
Ramachandran, M.
Abstract :
It is shown that laser chirp causes significant nonlinear distortions in the RF domain of analogue subcarrier systems in dispersive fibre links. The effect can be considerably reduced using the electrical compensation circuits shown.
