Abstract
A bidirectional optical transmitting and receiving module for connection to an optical waveguide, having an optical receiving device and an optical transmitting device, with the receiving device being arranged in one region of the optical axis of the optical waveguide, in front of its end surface. In order to make it possible with a transmitting and receiving module such as this for this module to be produced very easily and at the same time in order to very largely avoid electrical crosstalk between the transmitting device and the receiving device, the transmitting device is arranged away from the region of the optical axis of the optical waveguide, and at least one deflection device is arranged in the beam path between the optical waveguide and the receiving device and injects the light which is emitted from the transmitting device into the optical waveguide.
