We describe a scheme involving the insertion of segments of dispersion-compensating fiber, pumped to yield Raman gain, at one or more intermediate points within each 80-km-or-greater span between amplifier huts. With dispersion-managed solitons, the scheme is expected to allow for error-free, many-channel wavelength-division multiplexing, with high spectral efficiency, over transmission distances of many thousands of kilometers.
