We study a soliton transmission line with sliding-frequency filters, and we determine the limits on soliton stability imposed by the value of the free spectral range of Fabry-Perot étalon filters. From these limits, we infer the minimum channel spacing that is possible in a soliton wavelength-division-multiplexing system.
