Technofile : High fibre

By the end of this year, Lucent Technologies of New Jersey says that its
optical fibres will be able to carry up to 400 billion bits of data a second.
Although laboratory tests have produced similarly high-capacity fibres, this is
five times the throughput of the best commercial system. Lucent’s former parent,
the international telephone giant AT&T, will be the first customer to use
the technology.
