The subject of the invention relates to an optical fibre sealing unit that contains a basic bundle consisting of light-transmitting fibres, a signallin g bundle also consisting of light-transmitting fibres, a cable sheath and receiving bodies positioned at both ends of the cable sheath, the receiving bodies have an accepting space suitable for the fixing of at least some of t he light-transmitting fibres and a transmitting body that allows light to pass through it, the basic bundle and the signalling bundle are arranged in the cable sheath and the one end and the other end of the basic bundle are each fixed in the accepting space of a receiving body in such a way so that they can not move, one end of the basic bundle is fitted to the transmitting body of one of the receiving bodies and the other end of the basic bundle is fitt ed to the transmitting body of the other receiving body. The characteristic feature of the invention is that one end (21) of the signalling bundle (20) is fixed in the vicinity of the one end (11) of the basic bundle so as to preve nt light input, while the other end (22) of the signalling bundle (20) is clamp ed into the light-transmitting output member (60) in the vicinity of the other end (12) of the basic bundle (10).
