Abstract
A coupling device for coupling an end of a light-conducting fiber to an optical transmitter device and an optical receiver device. The receiver device comprises a light-collecting element arranged opposite an end face of the fiber end. The receiver is provided with an opening. The transmitter device comprises a transmitter element arranged opposite the opening behind the light-collecting element. A transmitter lens is provided for focussing light emitted by the transmitter device onto the end surface of the fiber end. In order to obtain a construction which can be coupled in a simple manner, a transparent body optically coupled to the fiber end, the light-collecting element and the transmitter element is arranged between the fiber end face and the light-collecting element body has reflecting side faces. As a result, substantially all the light emanating from the fiber end strikes the light-collecting element.
