PCT No. PCT/EP93/03009 Sec. 371 Date Jun. 20, 1995 Sec. 102(e) Date Jun. 20, 1995 PCT Filed Oct. 28, 1993 PCT Pub. No. WO94/10594 PCT Pub. Date May 11, 1994A coupling apparatus for optical data transmission has a plug element which is form-fitted into an associated socket element. The plug element contains guide channels for aligning and securing a group of individual optical waveguides within a single oversheath, so that the waveguide ends are flush with the mating face of the plug element. The socket element contains matching guide channels which are flush with the socket face, for receiving the optical signals from the corresponding plug channels. The socket element also contains circuitry for the detection, amplification, and re-transmission of the received optical signals.
