Abstract:
1. An optical fibre sealing unit, comprising: a basic bundle including light-transmitting fibres; a signalling bundle also including light-transmitting fibres; a cable sheath; receiving bodies positioned at both ends of the cable sheath, each of the receiving bodies having an accepting space suitable for fixing at least some of the light-transmitting fibres; and a transmitting body that allows light to pass through it; wherein the basic bundle and the signalling bundle are arranged in the cable sheath, and one end and another end of the basic bundle are fixed in the accepting space of a respective one of the receiving bodies in such a way that they cannot move; wherein said one end of the basic bundle is fitted to a transmitting body of one of the receiving bodies, and said another end of the basic bundle is fitted to a transmitting body of another of the receiving bodies; and wherein one end of the signalling bundle is fixed in a vicinity of said one end of the basic bundle so as to prevent light input, and another end of the signalling bundle is clamped into a light-transmitting output member in a vicinity of said another end of the basic bundle.
