摘要： An optical fiber cable for detecting a low temperature comprising a center member made of a material having a low coefficient of linear expansion and one or more longitudinally extending grooves in each of which at least one optical fiber is placed, (i) wherein at least one optical fiber comprising a core and a cladding both made of silica glass is placed in each of said grooves and the interior space of the groove which is not occupied by the optical fiber or fibers may be filled with a resin which has a low glass transition temperature; or (ii) wherein each of the optical fibers placed in each of said grooves, have different coating structures from each other and/or different fiber structures from each other so as to detect a low temperature in different temperature ranges.

摘要： There is provided a flat optical fiber cable comprised of a plurality of plastic coated optical fibers arranged parallel to one another and enveloped within a fiber-reinforced plastic jacket and possessing enhanced mechanical strength and thermal stability. A plurality of the flat optical fiber cables may be stacked together and surrounded by a plastic sheath which does not require additional strength members in view of the inherent strength of the flat cables contained therein.

摘要： An improved composite overhead stranded conductor obtained by providing an optical fiber cable in an overhead power line formed by stranding a plurality of conductors, or in an overhead earth wire which is extended in parallel with such an overhead power line. A spacer having a plurality of axially extending helical grooves formed in an outer surface thereof is positioned within a protective tube. Respective optical fibers and/or optical bundles are received in each of the grooves. Each of the grooves has a width substantially equal to the outer diameter of the optical fiber and/or the optical bundles received therein so that movement of the optical fibers and/or the optical bundles in the grooves in the circumferential direction of the spacer is restricted.

摘要： An optical fiber cable is described comprising a linear center member having at least one longitudinal and spiral groove in the surface thereof, one coated optical fiber received in each groove, an outer sheath that encloses the center member, and a jelly-like material with which the space around each optical fiber is entirely filled. A process for producing such an optical fiber cable is also described.
