Abstract: The present invention relates to a barrier tape used as part of a communication cable to improve crosstalk attenuation. The barrier tape is provided with one or more barrier layers of discontinuous conductive segments. Conductive segments of one barrier layer are preferably sized and shaped to overlie gaps between conductive segments of another barrier layer.

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.

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.
