IEEE approves 3.2 Gb/s IEEE 1394 high-speed serial bus specification

Logo FireWireIEEE 1394, better known under the brand names of Firewire and i.Link, will get a speed bump before the end of the year: The IEEE has approved the new IEEE 1394-2008 specification that provides support for a bandwidth of up to 3.2 Gb/s.

Firewire has come a long way. From the initial development by Apple in the late 1980s, to the technology??™s completion in 1995 and surge in popularity in the early 2000s, the technology has become a serial bus interface common in Sony and Apple computers as well as a range of consumer electronics devices such as video cameras.

Most IEEE 1394 devices are still running on the S400 (400 Mb/s) specification despite the fact that S800 (800 Mb/s) was introduced with the IEEE 1394b spec in 2003. The problem with this spec was a different connector than the design that was used for S400. However, bilingual cables that are compatible with S400 and S800 ports are available.

The IEEE today announced that it formally approved the IEEE 1394-2008 spec, which will introduce support for S1600 (1.6 Gb/s) and S3200 (3.2 Gb/s) while offering full backwards compatibility with S400 and S800 ports. Down the road, it is expected that IEEE 1394 will scale up to 6.4 Gb/s.

Firewire and i.Link desperately need the upgrade in order to remain competitive with USB, which will receive an upgrade to 4.8 Gb/s in version 3.0. The IEEE 1394-2008 spec will become available in October, according to the IEEE. The USB 3.0 spec is expected to be published by the end of this year.
