摘要	The invention relates to an arrangement for optically coupling an optical waveguide to an optical unit of an optical module. The optical module has a reference geometry, which defines a first axis of symmetry. There is an offset between the optical axis of the optical unit and the axis of symmetry of the reference geometry. The invention provides a coupling element which eliminates the offset. The coupling element has, for this purpose, a hole, which is delimited by an inner surface, the inner surface of the coupling element defining a second axis of symmetry. The first axis of symmetry and the second axis of symmetry extend parallel to one another and have an offset with respect to one another which is essentially the same as the offset between the optical axis of the optical unit and the first axis of symmetry of the reference geometry as regards direction and magnitude. Furthermore, a beam-shaping element having an optical axis, which coincides with the second axis of symmetry, is provided on that side of the coupling element which faces the optical unit.
