Cable with offset filler

摘要

A cable comprising at least two pairs of twisted conductors (more specifically, relating to twisted pair communication cables for high-speed data communications applications) is disclosed. The cable includes at least two twisted pairs of insulated conductors, a non-conductive filler, which includes a base portion and at least one extension, the base portion including a plurality of legs, at least one leg having a length approximately equal to the diameter of one of the twisted pairs of conductors, the plurality of legs defining pockets with the twisted pairs of conductors being positioned within the pockets, the extension(s) extending radially outwards from the leg(s), and a jacket that surrounds the twisted pairs of conductors and the filler, the extension of the filler creating a ridge on the exterior of the jacket that extends along the length of the cable. The filler may be helically twisted over a certain 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.
