How much data can you shove through a fiber optic cable? Quite a lot, as it turns out
. Using the ITU standard 50 GHz dense wavelength division multiplexing
grid, not only can you easily do 80 x 10 Gbps channels in a single fiber pair, but recent advances in modulation technology mean that with QPSK, 4QAM or 16QAM modulation, 1/80th of a dark fiber pair can carry a 100 Gbps
signal in the optical space previously occupied by a single long distance 10 Gbps circuit.

Up here in the Northern Hemisphere, it's time to break out the sweaters. Wool too itchy for you? (It is for poor Simon Cowell.
) Cashmere and alpaca are easier to wear; a surface comparison shows why
. But you can also steer clear of animal fibers altogether and opt for fabric made from wheat
. For that matter, while you're at the greengrocer, also pick up some bamboo
), soy (1
, corn (1
