Abstract:
An optical fiber coupling unit comprising:an optical fiber and a sleeve, wherein the optical fiber has a sheathing, and the end portion of the optical fiber is accommodated in the sleeve and has a portion of the sheathing removed, the sleeve further comprising an inner sleeve and an outer sleeve, the inner sleeve being arranged on the end portion of the optical fiber, and the outer sleeve extending with a sleeve portion remote from the one extreme end of the optical fiber over a port ion of the sheathing and having about the same outside diameter as the sheathing, and the outer sleeve having a planar surface adjacent to its circumferential surface and an end face, the sleeve being arranged on an end portion of the optical fiber with the end face terminating flush with an end of the optical fiber, thereby forming a continuous coupling face so that the optical fiber coupling unit can be placed onto an optical waveguide component to establish an optical coupling.
