ABSTRACT: "Optical coupling device". The coupling device serves to couple an end (1) of a light-conducting fibre to an optical transmitter device (3) and an optical receiver device (5). The receiver device (5) comprises a light-collecting element (17) arranged opposite an end face (13) of the fibre end (1) and provided with an opening (19). The transmitter device (3) comprises a transmitter element (7) arranged opposite the opening (19) behind the light-collecting element (17) with a transmitter lens (9) for focussing light emitted by the transmitter device onto the end surface (13) of the fibre end (1). In order to obtain a robust construction which can be composed in a simple manner, a transparent body (21) optically coupled to the fibre end (1), the light-collecting element (17) and the transmitter element (7) is arranged between the end face (13) and the light-collecting element (17), this body having reflecting side faces (27), as a result of which substantially all the light emanating from the fibre end strikes the light-collecting element (17).
