Patent ID: 7121738

Claim:
A bidirectional optical transmitting and receiving module for connecting to an optical waveguide defining an optical axis, the transmitting and receiving module comprising at least one optical receiving device and at least one optical transmitting device, wherein the receiving device is aligned with the optical axis, wherein the transmitting device is arranged away from the optical axis, and wherein the transmitting and receiving module further comprises at least one deflection device arranged in the optical axis between the optical waveguide and the receiving device and aligned such that the deflection device deflects light emitted from the transmitting device into the optical waveguide, wherein the receiving device and the transmitting device are arranged alongside one another on a printed circuit board, and further comprising a translucent material formed over in an optically active zone of the receiving device, wherein an outer face of the translucent material facing the optical waveguide has an optical disturbance point, and wherein the optical disturbance point forms a deflection element of the deflection device, and wherein the optical disturbance point is formed by a groove.
