An optical-fiber-characteristic-evaluating apparatus includes a measuring unit and an analyzing unit. The measuring unit measures, in one arbitrary direction, dependence Fφ(φ) of an electric field F of a measurement-object mode, which is one of high-order spatial modes of a multimode optical fiber that is to be evaluated, upon an angle of divergence φ in a far field by performing FFS. The analyzing unit obtains dependence fr(r) of the electric field F of the measurement-object mode upon a fiber-radial-direction position r at the exit end of the multimode optical fiber by performing a calculation in accordance with a predetermined expression containing Fφ(φ).
