Patent CA-2582877-A1 (CA)
Inventor: TYLER JAMES S
IPC: H01B13/22
Filed: 2007-03-28
Abstract: A data communication cable can comprise multiple pairs of twisted conductors within an outer jacket. A shielding can be disposed between the conductors and the outer jacket. The shielding may be an asymmetrically clad alloy steel (ACAS) tape wherein the copper cladding of the shield is thicker on a first side and thinner on a second side.  When the tape is positioned between the conductors and the jacket, the thicker copper layer can be positioned adjacent to the conductors. The thicker copper layer can reduce the capacitive coupling between the conductors and the steel layer of the shielding tape without the added expense of an inner jacket or increased insulation thickness between the conductors and the shielding tape. The tape may also reduce lightning noise and other electromagnetic interference. Additionally, copper layers of the tape can help prevent corrosion of the inner steel layer.
