This came up last night while we were putting racks together for a new
data center. Someone mentioned that it was theoretically possible to
put an infinite amount of information through a fiber because you could
have an infinite number of carriers even though the total available
frequency response was finite. I declined to argue with him, because
he
is always right, even when he's not. That reminded me of something I
....
Tom,
Perhaps you could explain to him that since he makes the assumption that
the width of a carrier (a single frequency) is zero and that therefore an
infinite number could fit within a finite bandwidth, he has overlooked
the use of more common media (eg phone lines) to carry an "infinite
amount of information" by this magical technique.
Don't disabuse him of his concept that a signal of zero bandwidth can
carry information at any rate above zero. He might even seek to patent
the method!
Such misconceptions are not unusual amongs IT experts who's education
started and ended with MS certification.
