Experimental and theoretical evaluation of distortion effects on SCM optical transmissions due to the joint action of static chirping, dynamic chirping and dispersive channel

In optical CATV systems based on subcarrier-multiplexing technique, the joi nt action of semiconductor laser chirp and fiber chromatic dispersion gives rise to intermodulation distortion phenomena affecting the transmission pe rformance. This problem has been explained analytically, leading to a model valid for every kind of modulating signal and explored in the case of a Ga ussian process. In this paper, the model is developed for the important spe cific case of an analogue SCM modulating signal. The results are assessed e xperimentally.
