Abstract
An arrangement for optically coupling an electro-optical transducer module to a light waveguide uses two lenses wherein the first lens is arranged in front of the electro-optical transducer module axially offset relative to the axis of the transducer module and a second lens is arranged in front of the light waveguide axially offset relative to the optical axis thereof. The optical axes of the two lenses are also axially offset relative to one another so that disturbing back-reflections are drastically reduced without diminishing the coupling efficiency of the arrangement.
