someone want to look at this please. France Telecom sets world record with one-terabit-per-second data transmission Paris, June 8, 1999 Teams at France Telecom's CNET research center have succeeded in transmitting data at a rate of one terabit (or 1,000 billion bits) per second over a distance of 1,000 km using conventional optical fiber. This corresponds to the equivalent of 100 encyclopedias with 28,000 pages each per second. This laboratory demonstration pulverized the world record, marking the first time that this quantity of data has been transmitted over such a distance with so few amplifiers (optical amplifiers are used in fiberoptic telecommunications networks to maintain the quality and intensity of signals). The achievement was presented last February to participants at the OFC '99 Optical Fiber Communication Conference in San Diego, in the United States. With this experiment France Telecom has demonstrated the potential of so-called "soliton" transmission technology. Solitons are light pulses that maintain their shape over long distances. This technology clearly has substantial performance headroom, which is important because it is compatible with existing network infrastructures. This record will have significant impact, since transmission technologies based on this approach will multiply network capacity and optimize infrastructures to enable greater throughputs, thus accommodating rising demand linked to the Internet and multimedia applications. Capitalizing on the work of its CNET research center, France Telecom will work with partners in the telecommunications industry to develop sophisticated network technologies that enhance data transmission capabilities.
