ABSTRACT:
A fibre-optic cable has a bundle of glass-fibre or silica-fibre strands extending along its length, each end of the fibre-bundle being sealed in a metal ferrule. A sheath of woven glass-fibre or silica-fibre extends about the fibre-bundle and is secured at each end to a respective ferrule in tension, such that the sheath is constricted onto the fibre-bundle along its length. The cable has an outer convoluted metal shell which is sealed at each end to a respective ferrule. A sleeve of elastic material extends around the fibre-bundle and the sheath, within the outer shell, and serves to support and cushion the fibre-bundle along its length. The sleeve may be of a woven fibre including glass-fibre or silica-fibre, and asbestos-fibre, or the sleeve may be of an elastomeric substance. A metal braid sleeve covers the outer surface of the convoluted metal shell. The cable may be included in a radiation pyrometer to transmit radiation to a radiation sensor.
