Abstract
A quad cable includes four conductors arranged as two differential pairs for carrying the differential signals TPA and TPB. Preferably, the quad cable is used to transmit data signals between devices within an IEEE 1394 network. The two differential conductor pairs are included, with filler material, within a braided inner shield. A shield separator is formed outside of the braided inner shield. A braided outer shield is formed outside of the shield separator. The shield separator provides electrical isolation between the inner and outer shields. A cable jacket is formed outside of the braided outer shield to encase the cable. Each end of the cable includes a cable connector having a plurality of pins for coupling to a receiving connector. The four conductors and the inner shield are each coupled to a respective pin within each cable connector. When coupled to a receiving connector, the outer shield is coupled to a housing of the connector. Within unit electronics at the port housing the receiving connector, a capacitor is preferably coupled between the inner shield and the outer shield. Preferably, the quad cable has a length of 4.5 meters and includes 24 gauge wire for the conduc…
