Abstract : analyzes the performance of unipolar ocdma system using optical orthogonal code ( ooc ) considering the dispersion and nonlinearity effect of the transmission medium . theoretical analysis demonstrates that dispersion and nonlinearity effect deteriorate the system performance . the performance of ocdma system assuming dispersion - shifted fiber as transmission medium is very close to the case neglecting the dispersion and nonlinearity effect . assuming rz initial pulse and optical hard limiter are also possible solutions
