Abstract :
Eliminating dispersion fast and early on is a critical concern when building next generation optical networks. Dispersion penalty has been investigated widely in 1550 nm fiber-optical links transmitting different kind of signals. However, only few papers were addressed to the harmonics generation effect. This paper presents theoretical and experimental results on estimation of harmonics in the transmission. An approach to overcome the radio frequency carrier suppression effect in optical links based on the joint effect of SOA chirp, chromatic dispersion and nonlinearities in optical fiber has been studied. The frequency notches caused by the dispersion induced carrier suppression effect may be sharply alleviated and the transmitted digital signal performance can be improved. The saturated SOA also affects the level and nature of harmonics.
