    摘要: Colorless twisted pair communication cables may include a plurality of twisted pairs of individually insulated conductors and a jacket formed around the plurality of twisted pairs. The cable may be formed to be completely free of colorant or to include a cable core defined by the jacket that is fee of colorant. Additionally, physical indicia may optionally be incorporated into the cable to facilitate identification of the plurality of twisted pairs.

    摘要: An optical fiber cable that includes reduced or minimal use of colorant may include a single optical fiber component and a jacket formed around the optical fiber component. The optical fiber component may include at least one optical fiber and a buffer layer formed around the at least one optical fiber. The buffer laying may include one or more first polymeric materials that are not blended or compounded with any colorant, and no colorant may be formed on an outer surface of the buffer layer. Additionally, the jacket may include or more second polymeric materials that are not blended or compounded with any colorant.

    摘要: Methods for forming discontinuous shields or shield structures for use in a cable are provided. A layer of dielectric material may be provided that extends in a longitudinal direction and has a first width across a width direction perpendicular to the longitudinal direction. Additionally, a layer of electrically conductive material may be formed on the dielectric material, and the layer of electrically conductive material may extend in the longitudinal direction and may have a second width across the width direction that is less than the first width. Respective gaps may be formed through both the electrically conductive material at a plurality of locations along the longitudinal direction, and each gap may span across the width direction by a distance greater than the second width but less than the first width.

    摘要: An optical fiber cable having reduced or minimal colorant may include a plurality of optical fiber components and a jacket formed around the plurality of optical fiber components. Each optical fiber component may include at least one optical fiber and a buffer layer surrounding the at least one optical fiber. The respective buffer layers may be free of colorant, and physical indicia may be selectively formed as surface variations on a suitable number of buffer layers to facilitate identification of the plurality of optical fiber components. The jacket may include one or more polymeric materials that are not blended or compounded with any colorant.

    摘要: A cable may include a plurality of twisted pairs of individually insulated conductors, a separator positioned between the twisted pairs, and a jacket formed around the twisted pairs and the separator. The separator may include a longitudinally extending spine positioned between the plurality of twisted pairs, and a plurality of projections extending from the spine with each projection extending between a set of adjacent twisted pairs. Additionally, a plurality of longitudinally spaced radial ridges may be incorporated into the separator. Each ridge may extend from a surface of one of the plurality of projections towards one of the plurality of twisted pairs in order to provide increased separation distance.

    摘要: A cable may include a plurality of twisted pairs of individually insulated conductors and a separator positioned between the plurality of twisted pairs. The separator may include a first longitudinally extending tape structure having a first longitudinal fold formed between its widthwise edges and a second longitudinally extending tape structure having a second longitudinal fold formed between its widthwise edges. Additionally, the first tape structure and the second tape structure may be bonded together along a longitudinally extending line proximate to the first and second longitudinal folds. A jacket may be formed around the plurality of twisted pairs and the separator.

    摘要: Communication cables incorporating a plurality of twisted pair components formed around a central member are described. A central member may extend lengthwise along a longitudinal length of a cable, and the central member may include a channel extending lengthwise that defines a longitudinal cavity through the central member. A plurality of twisted pair components may be formed around the central member, and each component may include a plurality of twisted pairs of individually insulated electrical conductors and at least one shield layer. The shield layer may include electrically conductive material, and the shield layer may be formed around at least one of the plurality of twisted pairs. Additionally, the shield layer may be in direct contact with the central member. Further, a jacket may be formed around the central member and the plurality of twisted pair components.
