A terminating sleeve (1) for optical waveguides, having disposed at its distal end (3) an optical waveguide insertion opening leading into an optical waveguide receiving channel (8) disposed in the longitudinal direction in the terminating sleeve (1), the terminating sleeve (1) being formed integrally with a coupling means (6) disposed at the proximal end and serving for coupling and uncoupling light, the optical waveguide receiving channel (8) extending from the optical waveguide insertion opening up to the coupling means (6) and the terminating sleeve (1) inclusive of the coupling means (6) being made from an optically transparent material. The optical coupling means (6) has a convexly curved surface (61) on the side directed towards the terminating end of the terminating sleeve (1). This provides the optical effect of a convex lens by a light beam (15). However, it is also possible to provide other optical effects by a different design of the optical coupling means (6) directed towards the terminating end. For example, thi surface may be a concavely curved surface, e.g. when the optical area of a complementary connector has a larger diameter than the optical coupling means (6) e.g. in case of an optical coupling with a light-emitting diode or a phototransistor in the complementary connector. The surface of the optical coupling means (6) located at the terminating end of terminating sleeve (1), however, may also be a planar surface oriented either perpendicularly to the OWG axis or at an angle thereto. An inclined planar surface may be used when reflections of the light coming from the OWG are to be avoided or at least reduced on the planar surface. |
