ABSTRACT OF THE DISCLOSURE A device, which provides a high positioning precision and good coupling efficiency for producing an optical coupling between a plurality of first optical waveguides having one spot diameter and a plurality of second optical waveguides having a different spot diameter, comprises optical lenses and a plate arranged between the end faces of the first and second waveguides lying opposite to one another, the plate has one flat surface facing toward the first waveguides and a second flat surface facing toward the second waveguides, the plate having an arrangement for positioning an optical lens between each pair of waveguides. The optical lenses may be planar lenses formed on a flat surface of the plate or may be spherical lenses held in conical depressions on one of the surfaces of the plate. In one embodiment, the plate has depressions on both sides, which may receive spherical lenses. In the arrangement with the planar lenses, the opposite side may be free of depressions or have depressions for receiving optical fibers forming one of the groups of waveguides.
