IEEE 1394

(computer science)
The standard for connecting storage, digital audio and video, and other peripheral devices to personal computers at data transfer rates up to 400 million bits per second. Also known as firewire.

IEEE 1394

FireWire

Officially the IEEE 1394 High Performance Serial Bus (HPSB), FireWire is a high-speed interface developed and promoted mostly by Apple for video transmission. Introduced in 2000, FireWire was added to camcorders and a variety of A/V equipment. Even early iPods could connect via FireWire. However, on modern camcorders, FireWire was replaced with USB, HDMI and other video outputs.

FireWire 400 and 800
FireWire 400 was limited to a distance of 4.5 meters. In 2003, FireWire 800 increased the range to 100 meters and doubled the transfer rate. FireWire supported 63 devices, real-time data transfer, hot swapping and simultaneous multiple speeds. The faster 1600 and 3200 versions never got into production. See PC data buses.

FIREWIRE VERSION TRANSFER RATES1394a - 4.5 METER CABLE LENGTH

  FW400     400 Mbps


  1394b - 100 METER CABLE LENGTH

  FW800     800 Mbps
  FW1600   1600 Mbps
  FW3200   3200 Mbps



FireWire Sockets and Compatibility
FW800 was backward compatible with FW400. One end of a "bilingual cable" had an FW800 plug, while the other end was FW400. Sony's i.Link was a miniaturized socket that connected to cables with i.Link, FW400 or FW800 at the other end.







Easy to Tell
FireWire sockets were easily distinguished from their USB counterparts.







Dual Mode FW/USB
This external hard drive connected to the computer via FireWire or USB, whichever cable was plugged in.
