DC CAFCFirst Claim
1. A communications cable comprising:
- a plurality of twisted pairs that carry communications signals;
a pair separator disposed among the plurality of twisted pairs, the pair separator comprising a central body portion and a plurality of arms radially extending from the central body portion, each pair of adjacent arms defining a channel; and
a cable covering surrounding the plurality of twisted pairs and the pair separator along the length of the cable;
wherein at least one twisted pair of the plurality of twisted pairs is respectively located in the channel defined by each pair of adjacent arms;
wherein the plurality of twisted pairs and the pair separator are helically twisted together along the length of the cable; and
wherein the cable covering does not include an electrically conductive shield.

Abstract
The present invention is for 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.
