Abstract:
1. A coupling arrangement for optically coupling a multi-channel optical plug-in element to at least one opto-electronic converter of a multi-channel transmitting or receiving unit, the coupling arrangement comprising: a coupling unit which comprises: a first coupling side for optical coupling to the multi-channel optical plug-in element, a second coupling side lying opposite the first coupling side for optical coupling to the at least one opto-electronic converter, and a multiplicity of high-precision through-bores for optical waveguides, said through-bores being arranged in a plane and extending from the first coupling side to the second coupling side in the interior of the coupling unit, wherein the coupling unit is of single-piece design, the coupling unit has, on its upper or lower side, a cut-out which partially exposes the through-bores for the optical waveguides in the interior, and the coupling arrangement furthermore comprises an additional auxiliary part which can be removed from the coupling unit and has a protruding knob configured for the coupling unit to be arranged on the auxiliary part after manufacture of the coupling unit in such a manner that the knob projects into the cut-out of the coupling unit and comes to rest adjacent to the through-bores for the optical waveguides and prevents the optical waveguides from leaving the through-bores in the region of the cut-out.
