Reduced alien crosstalk electrical cable with filler element
First Claim
1. An electrical cable, comprising:
- a cable jacket defining a central longitudinal axis;
a plurality of twisted pairs of insulated conductors oriented longitudinally within said cable jacket, each of said twisted pairs of insulated conductors defining a width;
a filler element disposed in said cable jacket and located adjacent to at least one of said twisted pairs of insulated conductors, said filler element defining a width that is substantially larger than said width of each said twisted pairs of insulated conductors, and said filler element having a central axis laterally offset from said central longitudinal axis of said cable jacket, said filler element reduces alien crosstalk from an adjacent cable; and
at least one separator disposed in said cable jacket between said twisted pairs of insulated conductors to reduce crosstalk between said twisted pairs of insulated conductors.

Abstract
An electrical cable includes a cable jacket defining a central longitudinal axis and a plurality of twisted pairs of insulated conductors oriented longitudinally within the cable jacket. Each of the twisted pairs of insulated conductors has a width. A filler element is disposed in the cable jacket and is located adjacent to at least one of the twisted pairs of insulated conductors. The filler element defines a width that is substantially larger than the width of each the twisted pairs of insulated conductors. The filler element has a central axis laterally offset from the central longitudinal axis of the cable jacket. The filler element reduces alien crosstalk from an adjacent cable. A separator is disposed in said cable jacket between the twisted pairs of insulated conductors to reduce crosstalk between the twisted pairs of insulated conductors.
