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.
