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, a first extension located a distance from a center of the base, and a second extension located at an end of the base opposite from the first extension, the first extension being located a distance farther from the center of the base than the second extension, the base defining a number of regions, each of the regions receiving one of the pairs of the plurality of twisted pairs of conductors; and
c) a jacket that surrounds the plurality of twisted pairs of conductors and the filler, the first extension of the filler creating a ridge at an exterior of the jacket that extends along a length of the cable.

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.
