Coupling device for the ends of two groups of filametary lightguides

The invention relates to a device for pairwise coupling the ends of two groups of fibrous optical waveguides, which are held on a respective movable in the longitudinal direction of the optical waveguide carriage by means of clamping devices, so that the end faces of the ends of a group of optical fiber respectively against the end faces of Ends of the other group of the optical fiber are slidable, with an arranged between the carriage alignment block, which has for the alignment of the individual fiber optic guide grooves, in which sorted in the associated fan combs ends of the optical fiber sorted and held by different pressure forces pressing elements are held. In this way, a high positioning accuracy is achieved in a simple manner by virtue of the fact that for each group of optical fibers a pressing element (18,
