We show that solitarylike stimulated Raman excitations are possible in massive wavelength-division-multiplexed fiber-optic systems. These self-similar states can propagate across channels at a constant rate that depends on the total power launched in the system and the wave's spectral width. The evolution of these excitations under the action of noise and during collisions is investigated in detail.
