Abstract

An IEEE 1394 cable (76) includes two individually shielded twisted data pairs of wires, carrying differential signals TPA and TPB, and two power conductors, carrying power signals VP and VG. The two twisted data pairs of wires are each individually shielded by a braided shield. The cable (76) also includes an overall braided shield and a no smoke, no halogen, flame retardant jacket. Preferably, the cable has a length of 4.5 meters and includes 26 gauge wire for the two twisted data pairs. Longer, alternate embodiments of the cable incorporate heavier gauge wire for the two twisted data pairs. Preferably, the gauge wire used for the two power conductors is constant for the different lengths of cable. An active disconnect (72) is used to provide an active repeater between IEEE 1394 cables. The active disconnect (72) provides ports, into which cables are connected, and a physical connection including electronics necessary to form an active node on the IEEE 1394 serial bus (76). The active disconnect (72) receives signals from one port and resychronizes, encodes and transmits those signals out of the other ports. The active disconnect (72) draws power from the power conductors of the IEEE 1394 cables (80 and 84) which are coupled to it.
