| Abstract: | The small dielectric loss and third -order dispersion of optical fiber are introduced in the standered NLS equation and the evolution of the parameters of the optical soliton - like pulse is investigated by using the variational principle and perturbation method. We discuss the influence of the small dielectric loss and third - order dispersion to the propagation properties of soliton - like pulses. |

| Keywords: | soliton - like small dielectric loss third - order dispersion variational principle |
