NTT, Others Develop Ultra-Fast Net Technology
TOKYO (Nikkei)–Nippon Telegraph and Telephone Corp. (9432) and its partners have developed technology that enables household Internet connections with 1,000 times the data-carrying capacity of those currently available, it has been learned.
The team, which also includes the National Institute of Information & Communications Technology, NEC Corp. (6701), Mitsubishi Electric Corp. (6503), Hitachi Ltd. (6501), KDDI R&D Laboratories Inc. and Fujitsu Ltd. (6702), aims to make the technology commercially available by around 2020.
At present, optical fibers cannot transmit multiple types of signals simultaneously. The research team has come up with a device which, when connected to an optical fiber line, allows it to transmit four to 10 different signals at once. This raises the connection speed to 100 gigabits per second.
The test of the device, which was conducted on a 50km experimental line, enabled transmission of a 25-gigabyte image file — satellite photos of many parts of the world — in just two seconds.
The new technology, when it becomes widely available, will, for example, allow viewers to see images on a huge screen with four times the sharpness of current high-definition video. Possible applications for the technology include telemedicine and sophisticated home theater systems.
