In this paper,using the variational principle for the optical soliton like pulses in the optical fiber and taking the fifth order nonlinearity into consideration in the modified NLS equation,we investigated the evolution of the parameters of the optical soliton like pulses and we got the conclusion:the influences of the fifth order nonlinearity on the optical soliton like pulse have many differences from that on the bright soliton.
