Abstract
A telecommunication cable in which pairs of twisted together conductors are spaced apart to minimize capacitance unbalance and cross-talk. A central core member may be provided with the conductor pairs extending around the core member which may have spokes to separate the conductor pairs. Alternatively, the cable jacket has inwardly directed spacers which separate the conductor pins and hold them in recesses defined by the jacket.
Claims5
An electrical telecommunications cable comprising a plurality of pairs of individually insulated conductors, the conductors in each pair twisted together, a cable jacket surrounding the plurality of pairs of conductors, the jacket formed with a plurality of inwardly extending projections spaced apart circumferentially around the jacket, the projections converging towards a common center and having spaced apart inner ends disposed outwardly of the common center to define recess regions within the jacket, each recess region by a circumferentially extending portion of the jacket and two projections, one at each end of the circumferentially extending portion, and each pair of conductors is contained within an individual recess region with the pairs of conductors spaced apart by the projections.
