A class of the nonlinear disturbed coupled Schrodinger system was studied. Using the specific technique to relate the exact and approximate solutions, firstly, the corresponding typi- cal coupled system was considered. The exact shock travelling solution was obtained by using the mapping method. Then, the travelling asymptotic solutions of the disturbed coupled Schrodinger system was found by using an approximate method.
