A SCSI external cable for interconnecting external peripheral devices to a host computer system or other peripheral devices is provided. The SCSI cable is configured to be ultra-thin and flexible and is designed to handle high bandwidths and support longer cabling distances, relative to conventional SCSI cabling. The SCSI cable includes: (a) an inner non-conducting fiber; (b) a first layer of twisted pairs, each of the first layer twisted pairs being concentrically wrapped around the inner non-conducting fiber; (c) a second layer of twisted pairs, each of the second layer twisted pairs being concentrically wrapped around the first layer of twisted pairs; (d) an inner shield being concentrically wrapped in a first direction around the second layer of twisted pairs, the inner shield being in the form of a tape strip; (e) an outer shield being concentrically wrapped in a second direction around the inner shield, the second direction being opposite the first direction of the inner shield, and the outer shield is in the form of a plurality of flat copper filaments, the plurality of flat copper filaments provide the SCS external cable an increased degree of flexibility; and (f) a jacket configured to wrap around the outer shield. In one example, a separator can be wrapped around the second layer of twisted pairs, and before the inner shield, to assist in meeting the SCSI electrical requirements. In another example where the separator is not used, it is preferred that each wire in the first layer and the second layer has a respective first layer insulation and a second layer insulation, and the second layer insulation is configured to be thicker than the first layer insulation.
