Abstract
A light waveguide such as a monomode fiber is inserted into a bore in a body of ductile material, and is mounted and centered using a deformation punch having individual needles which can be moved independently of one another. This provides an improvement over a conventional technique, in which an annular punch is initially employed to exert pressure on the end face of a core member symmetrical to the axis of a sleeve having the core member. For adjustment in accordance with the conventional technique, an asymmetrical pressure is exerted onto the end face in a further process step, with individual punches serving as deformation tools.
