A Method of Cotrol of Dispersion and Non-Linear Effect in OCDMA System

The dispersion and non-linear effect on performance of optical Code Division Multiple Access (CDMA) system based on strict optimal (F,k,1) optical orthogonal codes are analyzed. Numerical result shows that the dispersion and non-linear effect can deteriorate the system performance, so the technology of dispersion compensation is necessary. Different from the traditional schemes, a new scheme of using None Zero Dispersion Shift Fibre (NZ-DSF) and Dispersion Compensate Fibre (DCF) is proposed to weak the non-linear effect when compensating the dispersion. Therefore the performance of system can be enhanced by the NZ-DSF.
