FIBER KEEPS ITS PROMISE
BY
GEORGE GILDER
"Today, I await the death of television, telephony, VCRs,
and analog cameras with utter confidence as Moore's law
unfolds." Rupert Murdoch, Ted Turner, John Malone, are
you listening?"
Get ready. Bandwidth will triple each year for
the next 25, creating trillions in new wealth.
Editor's note: Four years ago, Forbes ASAP published its first issue with
a stunning prophecy by contributing editor George Gilder. Fiber optics,
said George, had the potential to carry 25 trillion bits per second down
a single strand. This represented a ten-thousandfold leap in carrying
capacity over the 2.5 billion bits "barrier" long assumed by most experts
in the field. What did George see that others had missed? One, a
little-recognized (at the time) breakthrough called an erbium-doped
amplifier, which keeps optical signals pure and strong over long distances.
The other was a deep technical shift, with roots in the 1940s-era work of
information theory pioneer Claude Shannon. If you believed Shannon, his
logic dictated a new messaging scheme called wave division multiplexing.
Though scorned by the experts four years ago, WDM now is emerging as the
winner George had prophesied.
The real winners will be all of us, as the coming world of cheap,
unlimited bandwidth unfolds and at last fulfills the true potential
