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 <i>n<sub>w</sub></i> for the same transmitter power. Further, an increase of <i>n<sub>w</sub></i> is needed at increased network load <i>g</i>; for example, to achieve the maximum throughput, <i>n<sub>w</sub></i> ≈ 10 and <i>n<sub>w</sub></i> ≈ 20 are needed corresponding to <i>g</i> = 0.5 and <i>g</i> = 1.0. It is found that when convolutional coding is applied, the required number of wavelength converters is greatly reduced at the full load <i>g</i> = 1.0.
