Abstract: In a method for producing a termination of an optical fiber bundle, the optical fiber bundle is combined at one end in a crimping sleeve, and the crimping sleeve is introduced with the end of the optical fiber bundle into a compression device having a crimping tool which matches the end geometry of the optical fiber bundle. Advantageous effects are achieved by the fact that the crimping sleeve is compression molded over the end of the optical fiber bundle with a predetermined crimping force by the crimping tool, and in that the crimping force is regulated during the compression molding process depending on the material of the crimping sleeve. In this case, the compression molding process is begun, carried out and ended depending on the distance, time and/or force by a regulating unit.
