Abstract
A communication cable with a barrier tape to improve crosstalk attenuation. The barrier tape is provided with one or more barrier layers of discontinuous conductive segments.
Claims20
A barrier tape for wrapping a core of twisted pairs of conductors in a communication cable, thereby attenuating alien crosstalk, said barrier tape comprising:
- an insulating substrate;
- a first barrier layer of conductive segments separated by gaps;
- and a second barrier layer of conductive segments separated by gaps;
- wherein the conductive segments of the first and second barrier layers overlay each other in a gridlike pattern such that gaps in one of the two barrier layers are substantially covered by conductive segments in the other of the two barrier layers.

A cable comprising:
- a plurality of twisted pairs of conductors provided in an inner core;
- an insulating layer surrounding said inner core;
- a barrier tape wrapped around said insulating layer, said barrier tape comprising:
- an insulating substrate;
- a first barrier layer of conductive segments separated by gaps;
- and a second barrier layer of conductive segments separated by gaps;
- wherein the conductive segments of the first and second barrier layers overlay each other in a gridlike pattern such that gaps in one of the two barrier layers are substantially covered by conductive segments in the other of the two barrier layers;
- and an outer insulating jacket.
