Family of conservative one-stepschemes of the sixth order of accuracy for Zakharov-Shabat system is constructed . The exponential integrator is a special case . Schemes based onrational approximation allow the use of fast algorithms to solve the initialproblem for a large number of values of the spectral parameter .
