TOKYO -- Oki Electric Industry Co., Ltd. (TSE: 6703) today announced that it has developed the world’s first single channel optical transmitter and receiver, succeeding to transmit 160 Gbit/s data over a distance of 640 km (approximately 396.8 miles) without forward-error correction, in an experimental level. Oki will exhibit this transmitter at the International Optoelectronics Exhibition '04 in Japan from July 13th, as the world’s first 160 Gbit/s transmission experiment conducted at an exhibition.

Oki succeeded in developing this optical transmitter that sends 160-gigabit data, equivalent to approximately 4 movies (8 hours) of data, in a single second based on OTDM (Optical Time Division Multiplexing) technology. The OTDM module uses a free-space interconnected module structure for its delay-line circuit, which allows allocation of four 40Gbit/s optical modulators that utilize the space. By multiplexing four 40Gbit/s modulators, Oki succeeded in generating 160 Gbit/s optical signal.

“As high-capacity data is transmitted in a single second, this transmitter will make a strong impact not only to the telecommunication industry, but also to the digital movie distribution and the network computing industry,” said Harushige Sugimoto, Chief Technology Officer at Oki Electric. “Oki plans to deploy sales to various research institutions as an interface equipment for ultra high capacity data transmission.”
