An optoelectronic coupling arrangement for a light waveguide cable (3), at each of whose ends an optoelectronic transmitter and/or receiver structural unit (1, 2) are optically coupled to, permit a signal or data transmission to or from an arbitrarily rotatable electronic system. The light waveguide cable (3) is flexible, but torsionally-stable or not rotated, and connected at its one end with the one optoelectronic transmitter and/or receiver structural element (1). The light waveguide cable (3) is separated at its other end into two axially opposing members which are each fastened in their lateral portions of a pivot bearing (4) and, consequently, are coupled axially rotatable optically and mechanically with each other. The lateral portion of the pivot bearing (4) associated with the end member of the light waveguide cable (3) is rigidly connected with a carrier (6) rotatable about an axis of rotation (5) on which the other optoelectronic transmitter and/or receiver structural unit (2) is fastened. An application for an optoelectronic coupling system according to the invention is in particular computer tomography systems.
