Oscillating tails of a dispersion-managed optical fiber system are studied for a strong dispersion map in the framework of a path-averaged Gabitov–Turitsyn equation. The small parameter of the analytical theory is the inverse time. An exponential decay in time of a soliton tail envelope is consistent with nonlocal nonlinearity of the Gabitov–Turitsyn equation, and the fast oscillations are described by a quadratic law. The preexponential modification factor is the linear function of time for zero average dispersion and a cubic function for nonzero average dispersion.
