Terabit Fiber On The Way

A Japanese company has developed technology to transmit a two-hour movie in 0.5 seconds, the world's fastest speed achieved with fibre-optic cables in the field, it says.

Kansai Electric used fibre-optic cables on power-transmitting steel towers to achieve the speed of one terabit per second, which is more than 100 times faster than inter-city data transmissions currently in use, a spokesman says.

The company, Japan's second-largest power supplier, has not decided when to put the technology into practical use but says it is possible that it would come in 2010 or later.
