| 摘要 |
A data communication cable includes a cable jacket surrounding a plurality of twisted pairs of insulated conductors disposed longitudinally over the length of the communication cable and arranged side-by-side to reduce cross-talk between the twisted pairs. The cable also includes a first region having a first thickness disposed between two regions having a second thickness. These regions, or another structure located on the outer surface of the jacket, are arranged to prevent symmetric stacking of several communication cables and thus reduce alien cross-talk arising from outside of the communication cable.
