Combined optical amplification and dispersion compensation in radio over fibre links

The study presents theoretical and experimental investigations on radio over fibre links concerning the effect of fibre dispersion. An approach is presented to overcome the radio-frequency suppression effect in optical links based on the joint effect of semiconductor optical amplifier chirp, chromatic dispersion and non-linearities of optical fibre. The results show that the frequency notches caused by the dispersion induced carrier suppression effect may be sharply alleviated and the performance of the transmitted signal can be improved.
