Impact of MAI on the performance of WDM/OCDM OBS networks using 2D wavelength-hopping and time spreading optical codes

The performance of an WDM/OCDM switch architecture is investigated under impairment of Multiple Access Interference (MAI). Analytical models are employed to evaluate the switch resources, such as the number of optical codes carried on each wavelength. In addition, the performance of Sparse Partial Optical Code Conversion (SPOCC) architecture is investigated using a hybrid technology, in Optical Burst Switching (OBS) networks, which employ wavelength and optical code division multiplexing. The simulation results indicate that both the increase of the number of optical codes per wavelength and the utilization SPOCC architecture, leads to considerable decrease of the Burst Blocking Probability (BBP). In addition, such hybrid approach also improves the utilization of network resources.
