Optical tap coupler for a cable comprising at least one optical conductor (1), consisting of a step-index glass fibre which is coated with a plastic coating. …<??>First means (3, 4, 5, 6, 7, 8, 12) make it possible to impart a predetermined position and a predetermined curvature to a portion of each optical conductor of the cable previously dissociated from the remainder of this cable in the region of the tap location. …<??>Second means (21, 22) make it possible to bring one end of the auxiliary optical conductor (30) mechanically, with a small angle of incidence, against each optical conductor of the cable in the zone in which this conductor has the predetermined curvature. …<??>Third means, for optical index adaptation, are provided between each end of the auxiliary optical conductor and the optical conductor of the cable against which this end is positioned. …<??>The invention is particularly applicable to buses for multi-station local area networks. …<IMAGE>… |
