This invention relates to an optoelectronic transceiver which has the following: an optical transmitter, an optical receiver, coupling means consisting of a first and second optical lens made with optically active interfaces for changing/deflecting optical paths of on the one hand optical output signals A of the optical transmitter to a connectable optical light guide and on the other hand of input signals E of the same light guide to the receiver, characterized in that the first lens has a concave reflection surface which lies inside in the coupling means for signals of the optical transmitter and the second lens has a convex transmission surface which lies outside for outgoing signals of the optical transmitter and a concave reflection surface which lies inside for incoming signals.
