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.
