The invention relates to a device having a first optical component (102) on a first printed circuit board surface (104), a second optical component (106) on a second printed circuit board surface (108), wherein the first printed circuit board surface (104) and the second printed circuit board surface (108) are substantially disposed successively parallel to each other such that the first printed circuit board surface (104) and the second printed circuit board surface (108) point in the same normal direction (110), and wherein both the first optical component (102) and the second optical component (106) can be coupled to an optical interface positioned in a normal direction (110) behind the first and the second printed circuit board surfaces.
