The IEEE 1394 FireWire compatible cable from Belkin attaches a device, like a digital camcorder (4-pin port), to your computer (4-pin port) at a transmission rate of up to 400 Mbps. The outer shield and inner shield (foil and braid) ensures compliance with IEEEs 1394 standards, which reduces radio frequency and electro-magnetic interference. Quad shielding (S-400 specification) ensures maximum speed with no data loss. The cable is hot-pluggable and features twisted pair construction for extreme velocity data transfer rates.
