Communication cable with improved crosstalk attenuation

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 barrier tape for use in a communication cable having a plurality of twisted pairs of conductors, the communication cable operational at a range of signal frequencies including a highest operational signal frequency, the plurality of twisted pairs of conductors having an average pair lay length, said barrier tape comprising:
an insulating substrate; and at least one barrier layer of conductive segments separated by gaps, said conductive segments having a longitudinal length greater than said average pair lay length and smaller than one quarter of a wavelength of a signal transmitted at the highest operational signal frequency.
