In order to study the evolution of separate spatial soliton pairs in a biased series centrosymmetric two-photon photorefractive crystal circuit, separate spatial soliton screening pairs solitons were proved to stay in a series circuit of two-photon photorefractive crystals based on the centrosymmetric two-photon photorefractive effect. The spatial envelope, dynamical evolution and stability of separate dark-dark and bright-dark soliton pairs were investigated numerically. The results show that only the dark soliton can affect the other soliton by light-induced current, but the bright soliton cannot.
