A graphical simulation system for the study of the physical performance of optical packet switching (OPS) nodes is accomplished. With the simulation system, the effect on bit error rate (BER) performance caused by a variety of factors, such as the crosstalk parameters of OPS nodes, numbers of cascaded OPS nodes, the length of optical output buffer, the traffic load, the amplitude fluctuation and the delay fluctuation of optical signals, are simulated and studied. The reliability of the simulation system is proved by the agreement between simulation results and analytical results.
