Abstract
The invention relates to an optoelectronic module for coupling light signals into and out of an optical waveguide. The module has a carrier having at least a first side, a light transmitter for emitting light signals, which is arranged on the carrier, a receiver for detecting light signals, which is arranged on the carrier, and a beam-shaping element for coupling light signals of the laser diode out of the module and for coupling light signals into the receiver. The light transmitter and the receiver are both arranged on the first side of the carrier, a shielding means serving to shield the receiver from optical and/or electrical interference signals. As a result, a bidirectional optoelectronic module is provided which is distinguished by signal conversion that is as precise as possible and, at the same time, is comparatively cost-effective in terms of production.
