In this paper, we researched the interaction of the fundamental black solitons between two same single-model fibers by variational method. We got the equations which show how the solitons' parameters change when the transmission distance changes. We also discussed how the initial phase difference influences the interaction between two solitons. We found it is true that the interaction between the dark solitons is less than that between the light solitons.
