Abstract--We propose a concatenated coding scheme, which
effectively reduces bit errors induced by soliton­soliton colli-
sions (SSC) in wavelength division multiplexing (WDM) soliton
transmission systems. A block line coding scheme, the sliding
window criterion (SWC) code, is developed based on the nature
of SSC-induced timing jitter in soliton communications. We
show, by simplified collision model simulations, that the SWC
code alone can decrease the SSC-induced timing jitter and, by
concatenation to a Reed­Solomon (RS) code, improve both the
bit rate and the channel spacing capacity in WDM systems. We
compare the performance of our scheme both analytically and
by simulations with those of various RS codes and concatenated
RS-convolutional code used in optical fiber transmission systems,
and show that high redundancy (overhead) does not always give
