Abstract

The invention relates to an optoelectronic transmission and/or reception arrangement. The arrangement includes a transmission and/or reception module containing an optoelectronic transmission and/or reception component, and a plug interface for the coupling of an optical fiber thereto. An optical waveguide section is arranged in the plug interface, and at one of its ends is optically coupled to the transmission and/or reception component. At its other end, the optical waveguide section is configured to be coupled to an optical fiber. The arrangement may further include a lens for optical coupling of the light between the optical waveguide section and the transmission and/or reception component. The lens and the optical waveguide section, in one example, are formed as a prefabricated subassembly, in which the lens is fixedly arranged at a defined distance from one end face of the optical waveguide section.
