The invention relates, among other things, to an assembly (10), comprising an electric conductive track carrier (20) and a component (30) arranged on the conductive track carrier. According to the invention, the component is a fiber-optoelectronic component and comprises: a housing (40), at least one electro-optic or optoelectronic component (50), at least one fiber-optic interface (60) connected to the electro-optic or optoelectronic component, and at least one electric interface (80) for connecting the component to the conductive track carrier, wherein the electric interface comprises at least one bent electric soldered connection element (100), the one end (110) of which is attached to a bottom connection section (120) of the housing bottom (125) and from there extends laterally outwardly such that the other end (130) of the soldered connection element – as viewed from above – protrudes laterally and is laterally soldered to the conductive track carrier outside of the outer housing contour (140), and wherein the soldered connection element is bent away from the bottom connection section such that the bottom connection section has a distance (A) from the conductive track carrier.
