Abstract

To lead an optical waveguide through a housing wall, the optical waveguide is, in one section freed of its protective layer and hermetically connected in a bushing by glass soldering it to the bushing. In at least one load-relieving section leading out of the bushing, the optical waveguide is fastened by its protective layer to an extension of the bushing. The bushing is hermetically set into the housing wall.
