Communication channels with crosstalk-mitigating material

摘要

Alien crosstalk in communication channels is decreased with the use of crosstalk-mitigating materials. Electrical communication cables may be provided with crosstalk-mitigating materials that surround twisted pairs in the cables. According to one embodiment, the crosstalk-mitigating material is an electrically resistive material having electrically conductive areas placed thereon. Such a material mitigates the effects of electrical and magnetic fields that would normally lead to alien crosstalk between communication channels.

1. A communications cable comprising:
a plurality of twisted pairs of conductors; and crosstalk-mitigating material surrounding said plurality of twisted pairs of conductors, said crosstalk-mitigating material comprising a substrate, a continuous thin metal layer, and a plurality of discontinuous conductive areas overlaid on said continuous thin metal layer, said conductive areas being separated from one another by gaps, said continuous thin metal layer being thinner than said conductive areas; wherein said plurality of said conductive areas are separated from one another by said gaps in a circumferential direction of said communications cable, and wherein each of said plurality of conductive areas is discontinuous.
