Abstract
A transmission and reception device, in which the transmission device and the reception device and the input/output end of a glass fiber are disposed optically in series with respect to one another. A laser diode is disposed on a central part of a photosensitive surface and the input/output end of the glass fiber is in turn adjusted in front of its end face. As a result of a cylindrical symmetry of the photosensitive surface and of the laser diode with respect to a fiber axis, a maxima of the coupling curves coincide with the fiber axis, so that a lateral fiber offset leads to only a moderate change in coupling efficiency.
