Abstract: A simple, inexpensive and compact overhead conductor incorporating an optical guide has a circumferentially rigid, circumferentially continuous aluminium central core 3 having an elongate compartment 2 within and throughout the length of the core in which is loosely housed an optical fibre 1. A layer 4 of steel wires 5 surrounds the central core 3 and a circumferentially continuous outer layer 6 of aluminium surrounds the steel wires. Aluminium of the central core 3 and / or of the outer layer 6 at least partially fills interstices between the steel wires 5. Use of expensive aluminium-clad steel wires is unnecessary.

Abstract: A process for manufacturing light-guiding articles based on vitreous polymers, which comprises immersing the article in a bath containing a substance having an index of refraction different from that of the polymer by at least 5.10 -2 units, and removing the solvent by heat-treatment at 20 to 150°C.

Abstract: Plastic optical fibers comprising as a core component a polymer predominantly containing methyl methacrylate and as a cladding component a copolymer lower in the refractive index than the core component, the plastics optical fibers being characterized by performing conjugate spinning with use of the cladding component which is vinylidene fluoride-tetrafluoroethylene copolymer having incorporated therein 5 to 50% by weight of a polymer predominantly containing methyl methacrylate.

Abstract: A heat-resisting optical fiber comprising a core and a cladding, characterized in that the core is made of a polymer comprising units of a methacrylic ester, of which the ester moiety has an alicyclic hydrocarbon group of not less than 8 carbon atoms, and the cladding is made of a transparent polymeric material having a refractive index of at least 3 % smaller than that of the core. This optical fiber has excellent heat resistance and good flexibility and can be used at a high temperature over 110°C.

Abstract: A fibre optic cable is helically wound on to an overhead high voltage conductor, and has an electrically nontracking outer jacket and is filled with protective material, or has a conductive outer jacket. The cable is guided off the conductor inside a conductive housing, and thence to earth potential along the inside of a nontracking shedded or convoluted tube.

Abstract: In the manufacture, for use in an optical cable element, of a tube of polymeric material, the drawn down extruded polymeric tube is annealed by causing it to travel through at least one elongate oven 20 into which is injected, preferably at a position 21 intermediate of the ends of the oven, air or other gas which will have no deleterious effect on, and which is at a temperature sufficient to effect annealing of, the drawn down polymeric tube. Preferably turbulent flow of hot gas is provided within the oven. Use of this method of annealing enables the speed of manufacture to be at least twice the speed of manufacture hitherto achieved.
