Abstract

An electrical cable that has a cable jacket defining a central longitudinal axis and at least first, second, third, and fourth twisted pairs of insulated conductors oriented longitudinally within the cable jacket and forming a core. Each of the twisted pairs of insulated conductors defines a width. A filler element is disposed in the cable jacket and 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 of the twisted pairs of insulated conductors. The filler element has a central axis laterally offset from the central longitudinal axis of the cable jacket, and the filler element is twisted around the core.

Claims

1. An electrical cable, comprising

a cable jacket defining a central longitudinal axis;

at least first, second, third, and fourth twisted pairs of insulated conductors oriented longitudinally within said cable jacket and forming a core, each of said twisted pairs of insulated conductors defining a width; and

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, said filler element having a central axis laterally offset from said central longitudinal axis of said cable jacket, and said filler element being twisted around said core, and said filler element being devoid of insulated conductors.

2. An electrical cable according to claim 1, wherein said cable jacket has an asymmetrical shape.

3. An electrical cable according to claim 1, wherein said filler element is a solid, unitary one-piece member.

4. An electrical cable, comprising

a cable jacket defining a central longitudinal axis, said cable jacket having an asymmetrical shape;

a plurality of twisted pairs of insulated conductors oriented longitudinally within said cable jacket and forming a core, each of said twisted pairs of insulated conductors defining a width; and

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, said filler element having a central axis laterally offset from said central longitudinal axis of said cable jacket, and said filler element being twisted around said core.

5. An electrical cable according to claim 4, wherein

said plurality of twisted pairs of insulated conductors includes at least first, second, third and fourth pairs of insulated conductors.

6. An electrical cable according to claim 4, wherein said filler elements is a solid, unitary one-piece member.

7. An electrical cable according to claim 4, wherein said filler element is devoid of insulated conductors.

8. 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; and
