In nonlinear optical fibers, the vector solitons can be governed by the systems of coupled nonlinear Schrodinger from polarized optical waves in an isotropic medium. Based on the Ablowitz - Kaup - Newell - Segur technology, the Darboux transformation method is successfully applied to two coupled nonlinear Schrodinger systems. With the help of symbolic computation, the bright vector one- and two-soliton solutions including one-peak and two-peak solitons are further constructed via the iterative algorithm of Darboux transformation. Through the figures for several sample solutions, the stable propagation and elastic collisions for these kinds of bright vector solitons are discussed and the possible applications are pointed out in optical communications and relevant optical experiments. In addition, the conserved quantities of such two systems, i. e., the energy, momentum and Hamiltonian, are also presented.
