Use of a system simulator to analyze the impact of PIN and APD photodiode on the performances of realistic DS-OCDMA for future access networks

The performances of a realistic optical direct sequence code-division multiple-access (DS-OCDMA) network have been evaluated with PIN and APD receivers. This comparison has been carried out including realistic system parameters as chromatic dispersion, multiple access interference (MAI), receiver noises (dark current shot noise and receiver thermal noise) and photodiode bandwidth. We analyze the error probability of the network taking into account these parameters.
