A glass fiber bushing is provided for a wall opening of a housing which has a light-transmitting or a light receiving component mounted therein, the component having an optically-active location to be optimally coupled to the tip of the glass fiber. At least in the region of the opening through the housing, the glass fiber is firmly surrounded by and is secured in a stiff tube which is inserted through the wall opening. An adjustment member which adjusts the glass fiber position is slipped with a tight clearance over the tube and/or over a transition piece which is secured to the tube. An end face of the adjustment member is oriented toward the exterior surface of the housing in the region surrounding the wall opening. At least close to the tip of the glass fiber, the outer diameter of the glass fiber or of a glass fiber protective layer is surrounded by the inner wall of the tube with so little play that the tube defines the position of the tip of the glass fiber. In a region between the adjustment member and the component the tube is plugged through an elastic membrane of the wall opening. A surface of the membrane is secured to the housing in the area of the wall opening. The end face of the adjustment member which adjusts the position of the tube and, therewith, the position of the glass fiber is secured to the exterior surface of the housing.
