Paper Abstract

The CSO (composite second-order distortion) induced by self-phase modulation (SPM) in an AM-VSB externally modulated CATV system which employs optical fiber Raman amplifiers (FRA) is studied theoretically in this paper. Firstly, the analysis of CSO is achieved by solving Schrödinger equation using perturbation method. And then numerical results are presented and discussed. According to the study in the paper, the SPM induced CSO performance can be improved by more than 10 dB by using FRA than using EDFA in CATV systems.
