The electro-optical module has a substrate with a mounting surface that is free from depressions. A surface-mounted component unit is disosed on the mounting surface. The component unit contains as integral components an electro-optical component and a lens which are aligned directly with one another. The surface serves, furthermore, as a reference plane for assembling a receptacle for an optical fiber plug.

To ensure laser safety, also in the case of a largest possible coupled optical power, during the direct optical coupling of a light-emitted component to an optical waveguide, an optical system includes coupling the light through a fiber end configured as a multimode step index optical waveguide having a numeric aperture larger than the half-width value of the angular distribution of the radiation emitted from the radiation source. To distribute the radiation fed into the actual optical waveguide over the largest possible angular range with regard to the luminous power, the coupling of the light beam into the fiber end is effected such that the coupled light beams are inclined in relation to the geometric axis of the optical core of the fiber end at a defined angle.
