ABSTRACT:
A bidirectional transceiver module for message and signal transmission via a light waveguide is formed of a lens coupling optics, a laser chip as a light transmitter, a light receiver, and a beam splitter intervening in the beam path. These parts are at least partially surrounded by a housing. They are designed such that, given reduced manufacturing expense, a lens coupling optics arranged immediately in front of the laser chip can be adjusted in a simple way and can be fixed in stable fashion. The laser chip is arranged on a common carrier between two carrier parts whose lateral surfaces neighboring the resonator faces of the laser chip are provided with mirror layers and are inclined at an angle of approximately 45.degree. relative to the resonator faces for beam deflection onto the lens coupling optics secured above the laser chip on at least one carrier part. The mirror layer neighboring the front side of the laser chip is provided with the beam splitter. The light receiver or an optical coupling for this is provided at the underside of the common carrier.
