摘要： An optical fibre element for use in an optical cable comprises a flexbile elongate member having within and partially bounded by the elongate member throughout its length an elongate compartment; at least one optical fibre loosely housed in the elongate compartment; and means for retaining the optical fibre within the elongate compartment. The elongate member is resiliently set in such a form that the central longitudinal axis of the member follows a longitudinally extending path which, between any two longitudinally spaced positions, is greater in length than the rectilinear distance between the two positions. When the resiliently set elongate member is subjected to a longitudinally applied tensile force, the elongate member will tend to straighten in a lengthwise direction against the action of its resilient set, thereby to reduce the tensile force applied to the optical fibre. When the tensile force is removed, the elongate member will return under the action of its resilient set towards its original form. Two or more such optical fibre elements may be assembled together to form an assembly of optical fibre elements for use in an optical cable.

摘要： An optical fibre ribbon structure suitable for loosely housing in a bore of an optical cable comprises an optical fibre ribbon which comprises a plurality of optical fibres arranged side by side and embedded in a plastics body and which extends lengthwise on and is secured to one surface of a plastics tape and two plastics insulated conductors, one of which insulated conductors extends lengthwise on and is secured to the surface of the tape on one side of the optical fibre ribbon and one of which insulated conductors extends lengthwise on and is secured to the surface of the tape on the other side of the optical fibre ribbon. Each insulated conductor has an overall diameter substantially greater than the overall thickness of the optical fibre ribbon. Each conductor may be of a resilient metal and each plastics insulated resilient conductor may be resiliently set in such a form that the ribbon structure follows a path of smoothly curved undulations whose axes of curvature lie transverse to the longitudinal axis of the ribbon structure.

摘要： An optical fibre element suitable for loosely housing in a bore of an optical cable comprises a plastics tape having transversely spaced on and secured to one of its major surfaces two plastics insulated electric conductors extending lengthwise of the tape and a second plastics tape overlying and secured to the plastics insulated conductors to form between the pair of plastics insulated conductors an elongate compartment. Loosely housed in the elongate compartment is an optical fibre ribbon comprising a plurality of optical fibres arranged side by side and embedded in an elongate plastics body. Each conductor may be of a resilient metal and/or each plastics tape may be of a resilient plastics material and each conductor and/plastics tape may be resiliently set in such a form that the optical fibre element follows a path of smoothly curved undulations whose axes of curvature lie transverse to the longitudinal axis of the element.
