Abstract

A high performance data cable which has an interior support or star separator. The star separator or interior support extends along the longitudinal length of the data cable. The star separator or interior support has a central region. A plurality of prongs or splines extend outward from the central region along the length of the central region. Each prong or spline is adjacent with at least two other prongs or splines. The prongs or splines may be helixed or S-Z shaped as they extend along the length of the star separator or interior support. Each pair of adjacent prongs or splines defines grooves which extend along the longitudinal length of the interior support. At least two of the grooves have disposed therein an insulated conductor. The interior support can have a first material and a different second material. The different second material forms an outer surface of the interior support.

Claims17

Dependent claims

A high performance data communications cable comprising:

a non-conductive interior support formed of a copolymer and having a longitudinally extending central portion and a plurality of arms radially extending from the central portion along the length of the central portion, each arm of the plurality of arms being adjacent to two other arms of the plurality of arms, the plurality of arms forming a plurality of pairs of adjacent arms, the plurality of pairs of adjacent arms defining a corresponding plurality of grooves;
a plurality of twisted pair conductors configured to carry data communications signals, only one twisted pair of the plurality of twisted pairs being respectively located in each groove of the plurality of grooves;
and
a cable covering surrounding the plurality of twisted pairs and the interior support along a length of the cable;
wherein the interior support is configured in combination with the cable covering to maintain the plurality of twisted pairs within the grooves defined by the plurality of pairs of adjacent arms of the interior support;
and
wherein the plurality of twisted pair conductors and the interior support are helically twisted together about a common central axis to close the cable.
