Kawasaki, Japan, December 4, 2007 -- Oki Electric Cable Co., Ltd. (TSE: 5815) today announced it has developed the industry's first "1394.b Long Cable (8 meters)" compliant to the IEEE1394.b standard. The product is a 1394.b cable, achieving an 800Mbps transmission speed. The product will soon be commercialized and Oki Electric Cable plans to launch sales from January 2008.

"We achieved an 800Mbps transmission speed over an 8 meter-long high-performance cable by improving our manufacturing technologies so the structure will uniform throughout the cable length," said Takashi Hattori, President of Oki Electric Cable. "We plan to provide our new cable to users for various applications in industrial equipment including industrial devices and robots."

Nowadays, with the increase in demand for machine vision in industrial equipment and robots, demand for higher speed and noise-resistant cables is growing rapidly. By adopting a proprietary cable structure and reviewing the materials used, Oki Electric Cable succeeded in developing this "1394.b Long Cable (8 meters)." By developing an IEEE1394.b standard compliant cable with a transmission speed of 800Mbps, the company achieved an industry first.

Though IEEE1394.b compliant cables are usually up to 4.5 meters in length, longer cables have been in demand as testing equipment has become larger. By adopting a completely different structure than conventional 1394.b cables, Oki Electric Cable succeeded in reducing attenuation significantly while transmitting data over an 8 meter cable.

The product will be displayed at the Accessory Corner of booth #29 at the 2007 International Technical Exhibition On Image Technology and Equipment (http://www.seiki-tsushin.com/ite/eng/index.html) at Pacifico Yokohama in Japan from December 5th to 7th. The following items will also be displayed: high-bending resistance Cat.5e LAN cables, high-sliding resistance cables (1394.b) and camera link cables.
