| 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. |
