The conditions of complete compensation for both the soliton self-frequency shift and the third-order dispersion are given. These forces, which are destructive to femtosecond pulse propagation, can be completely compensated for by the proper choice of the optical gain spectrum and the dispersion parameters of the optical fiber. This result is significant for achieving ultrahigh-bit-rate (>100 Gbits/s) optical transmission systems.
