Abstract

Performance analysis is carried out for a multihop optical ShuffleNet with full wavelength conversion to evaluate the effect of wavelength converters on the bit-error-rate (BER) and packet-error-rate (PER) performance. Computed results show that there is a significant decrease in BER with an increase in the number of wavelength converters nw for the same transmitter power. Further, an increase of nw is needed at increased network load g; for example, to achieve the maximum throughput, nw ≈ 10 and nw ≈ 20 are needed corresponding to g = 0.5 and g = 1.0. It is found that when convolutional coding is applied, the required number of wavelength converters is greatly reduced at the full load g = 1.0.
