Cable with offset filler
First Claim
1. A cable, comprising:
- a) a plurality of twisted pairs of conductors that extend along a length of the cable;
b) a first non-conductive member that extends along a length of the cable, the first non-conductive member having a plurality of outward extending legs that defines three or more pockets for separating the pairs of the plurality of twisted pairs of conductors;
c) a second non-conductive member that is a separate piece from the first non-conductive member, the second non-conductive member projecting radially outwardly from the plurality of twisted pairs of conductors, and the second non-conductive member extending helically along the length of the cable; and
d) a jacket surrounding at least the plurality of twisted pairs of conductors and the first non-conductive member, the jacket including a helical ridge extending along the length of the jacket, the helical ridge projecting outwardly from a main outer boundary of the jacket;
e) wherein each twisted pair of conductors defines a diameter, and wherein the helical ridge projects outwardly from the main outer boundary of the jacket a distance at least equal to one-quarter the diameter defined by each twisted pair of conductors.

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.
