摘要

Methods and apparatus directed towards communication cables and barrier tapes for use in communication cables are disclosed herein. In an embodiment, the present invention employs conductive segments within the communication cables and/or on the barrier tape.

主权项

1. A communication cable comprising:
an inner core, said inner core including a first pair of twisted wires, said first pair of twisted wires forming a first differential pair and having a first wire and a second wire; and a barrier tape positioned around said inner core, said barrier tape including a first layer of conductive segments separated by gaps and a second layer of conductive segments separated by gaps, said first layer of conductive segments being positioned closer to said first pair of twisted wires than said second layer of conductive segments; wherein at least two of said conductive segments of said second layer are positioned at least partially over one of said conductive segments of said first layer, wherein a longitudinal length of said one of said conductive segments of said first layer is selected such that a first signal carried by said first wire and a second signal carried by said second wire couple approximately equally to said one of said conductive segments of said first layer providing a net charge coupling from said first pair of twisted wires to said one of said conductive segments of said first layer, and wherein respective longitudinal lengths of said at least two of said conductive segments of said second layer are selected such that said net charge is at least partially coupled to said at least two of said conductive segments of said second layer.
