Abstract

An optical bidirectional transceiver module includes a module body having an opening, an inner hollow space and a fiber pin pushed through the opening into the inner hollow space. The fiber pin has a centric bored hole in which a light-conducting fiber is guided. A wavelength-selective filter or a beam splitter is located at a beveled end surface of the fiber pin. Radiation from an externally coupled light waveguide is emitted through the light-conducting fiber and reflected at the filter to a first optoelectronic component (transmitter). Received light radiation passes through the filter and impinges on a second optoelectronic component (receiver).
