Abstract A cable may be provided having a noise-suppression ferrite loaded magnetic tape wrapped in a spiral. The cable may have a strengthening cord at its core. Signal wires such as data wires and power wires may surround the strengthening cord. The signal wires may have copper cores that are coated with polytetrafluoroethylene insulating coatings. A metallized polyester tape may be wrapped around the signal wires to reduce electromagnetic interference. A braided copper shield may be formed over the metallized polyester tape. The magnetic tape may be wrapped around the metal braid. One or both edges of the magnetic tape may have uncovered areas in which no magnetic material is present. The cable may have connectors its ends. The magnetic tape wrap may extend from one connector to the other.
