Performance evaluation with receiver collisions analysis in very high-speed optical fiber local area networks using passive star topology

The problem of receiver collisions in high-speed optical fiber local area networks is studied in this paper. The configuration of high-speed multichannel LAN´s with wavelength division multiplexing techniques using an optical fiber bandwidth gives rise to receiver collisions phenomena. We give a detailed analysis and develop rigorous methods to examine the effect of receiver collisions in this type of multiaccess environment. The evaluations are carried out assuming Poisson arrivals and finite population and examine the throughput performance and the rejection probability at destination. Also numerical results are showing the throughput performance behavior as it compared with the protocol case without receiver collisions
