Nobody yet knows how fast information will travel in the twenty-first century. Three months ago the Nippon Telegraph and Telephone Corporation established a new standard for data transfer by sending a message at a rate of 14 trillion bits per second. In less technical language, that is the equivalent of transmitting 140 complete DVDs every second, or a full year’s worth of viewing in about thirty seconds. In an hour you could send or receive enough footage for a century of nonstop cinema. Or, if you preferred to read, you could acquire the entire archives of the New York Times and the New Yorker magazine-in less time than it takes to yawn. This staggering amount of information was channelled through a single 160 km-long optical fiber. Future networks are likely to carry millions of these magical strands, creating data streams of unimaginable speed.
