transport using Soliton
Pulses in Dispersion-Shifted Fiber
Fiber: Errorless data transmission: 50 Gb/s, at over 19,000
km, No Repeaters
Optic Cable: TAT-14 (map)
cable, which incorporates dense wave division multiplexing (DWDM)
with 16 wavelengths of STM-64 per fiber pair, is operating at a protected
capacity of 640Gbps, with a total capacity of 1.3 Tbps; enough
to transmit the content of more than 400 full length movie DVDs every second.

Light travels 1/8th
the thickness of a sheet of paper in 10 Fsec.
1 Fsec is to one second
as one second is to 32 million years.
next generation of computing--Optical Computing, will have CPU operations
and bus speeds measured in THz, data paths >>kbytes wide. Logic operations
will occur in ‘optical space’ as Soliton wave packets interact algebraically/logically--the
operations happen outside of silicon. The hardware: sub-micron LASERS communicating
across sub-micron 'free space,' both transferring and processing data,
stored in Terra Byte optical storage. [*]
