Cable with offset filler
First Claim
1. A cable, comprising:
- a) a plurality of twisted pairs of conductors;
b) a non-conductive filler including a base and a plurality of legs radially extending from a center of the base, the base and the legs defining a number of regions, each of the regions receiving one of the plurality of twisted pairs of conductors, each of the pairs of the plurality of twisted pairs of conductors is located within a portion of a circular cross-sectional area of the cable when positioned within the regions defined by the base, each of the legs of the plurality of legs having a length, the length of at least a first of the legs being longer than the length of other legs, the first leg extending beyond the portion of the circular cross-sectional area; and
c) a jacket that surrounds the plurality of twisted pairs of conductors and the filler.

Abstract
The present invention relates to cables made of twisted conductor pairs. More specifically, the present invention relates to twisted pair communication cables for high-speed data communications applications. A twisted pair including at least two conductors extends along a generally longitudinal axis, with an insulation surrounding each of the conductors. The conductors are twisted generally longitudinally along the axis. A cable includes at least two twisted pairs and a filler. At least two of the cables are positioned along generally parallel axes for at least a predefined distance. The cables are configured to efficiently and accurately propagate high-speed data signals by, among other functions, limiting at least a subset of the following: impedance deviations, signal attenuation, and alien crosstalk along the predefined distance.

14. A cable, comprising:
-
a jacket; a plurality of twisted pairs of conductors positioned within the jacket; and a filler arrangement positioned within the jacket, the filler arrangement including a non-conductive structure that extends along a length of the cable, the non-conductive structure including a center and dividers that radially extend from the center, the dividers including at least one longer divider having a length that is longer than that of other dividers, the dividers separating the twisted pairs of conductors; wherein the at least one longer divider includes an enlargement located at an end of the longer divider opposite the center of the non-conductive structure. - View Dependent Claims (15, 16, 17, 18, 19, 20)
