In clause problem of radiation selective excitation in multimode fibers is considered. Operator calculation method for variations of propagating radiation's initial modal power distribution due to abrupt fiber inhomogeneities is introduced. Results of numerical simulation and its comparison with calculations by well-known empirical formulas are provided.
