Abstract
We evaluate the bit-error-rate (BER) performance of a multihop optical
ShuffleNet with and without convolutional coding. Computed results show that there
is considerable improvement in network performance resulting from coding in terms of
an increased number of traversable hops from a given transmitter power at a given
BER. For a rate-1/2 convolutional code with constraint length K = 9 at BER =
10-9, the hop gains are found to be 20 hops for hot-potato
routing and 7 hops for single-buffer routing at the transmitter power of 0 dBm. We
can further increase the hop gain by increasing transmitter power.
