Abstract: A communications cable has a cable core with a plurality of twisted pairs of conductors and a metal foil tape disposed between the cable core and a jacket of the communications cable. The metal foil tape has a plurality of cuts that create a plurality of discontinuous regions in a metal layer of the metal foil tape. The metal foil tape is wrapped around the cable core such that the discontinuous regions overlap to form a plurality of overlapping regions. The overlapping regions producing capacitances connected in series, reducing an overall capacitance between the overlapping discontinuous regions. The plurality of cuts form a Y-shape cut having a first straight cut starting at one side of the metal foil tape and two cuts branching off of the first straight cut at opposite angles near a second side of the metal foil tape.

Abstract: A communications cable having a plurality of twisted pairs of conductors and various embodiments of a metal foil tape between the twisted pairs and a cable jacket is disclosed. In some embodiments, the metal foil tapes include a cut that creates discontinuous regions in a metal layer of the metal foil tapes. When the metal foil tapes are wrapped around the cable core, the discontinuous regions overlap to form at least one overlapping region. The cuts are formed such that overlapping region is small and limits current flow through the metal foil tapes, thereby minimizing alien crosstalk in the communications cable.

Abstract: In one embodiment a matrix tape includes a support layer, a metallic layer composed of metallic segments attached to the support layer and a barrier layer attached to the support layer opposite the metallic layer. In another embodiment a matrix tape includes a support layer, a metallic layer composed of metallic segments attached to the support layer and a strength member attached to the metallic layer opposite the support layer. In a third embodiment a method of manufacturing a matrix tape includes providing a payout and an uptake reel. Dispensing a tape with a support layer and a metallic layer from the payout reel, ablating the metallic reel with a laser, attached at least one of a strength member or a barrier layer to the tape, and spooling the tape on the uptake reel.
