Communication cable with improved crosstalk attenuation

摘要

A barrier tape used as part of a communication cable has one or more barrier layers of discontinuous conductive segments. Conductive segments of one barrier layer are preferably sized and shaped to overlie gaps between conductive segments of another barrier layer.

主权项

1. A communications cable comprising:
an inner core having a plurality of twisted wire pairs, each of the twisted wire pairs having a lay length wherein a lay length is defined as a length of one complete twist of a twisted wire pair; and a barrier tape wrapped around the inner core, the barrier tape having a plurality of parallelogram-shaped conductive segments wherein each conductive segment has a length that is greater than an average lay length of the twisted wire pairs and smaller than one quarter of the wavelength of a highest frequency signal transmitted over the twisted wire pairs.
