- Аннотация: Using the adiabatic approximation we consider the process of the nonlinear propagation of a basic optical soliton in a fiber with a cubic nonlinearity and losses. The latter are compensated by periodic or distributed amplification with a band width comparable to the width of the soliton spectrum. We obtain analytical expressions describing the evolution of the dispersions of the fluctuations in the momentum and in the position of the soliton peak. We establish that when the amplification band width and the width of the soliton spectrum are approximately equal they are very close to the quantum momentum- coordinate indeterminacy relations of a basic soliton propagating in an ideal lossless nonlinear waveguide. We give the correction to the Gordon-Haus quantum limit taking into account the frequency drag of the soliton carrier frequency under the amplification line contour
