ABSTRACT:
The coupling device according to the invention comprises two coupling members, each of which has a circularly cylindrical recess on one side. An end of a fiber to be coupled is centered in each recess by means of two sets of balls which are arranged one on top of the other. The first set of balls bears against the fiber end. The second set of balls bears on the first set and against the wall of the recess and presses the first set of balls against the fiber end. A spherical lens is arranged on the second set of balls so that the optical axis of the lens coincides with the axis of the centered fiber.
