LindyBill gave us that cool "Gee Whiz" laser diode factoid the other day.

Today's "Gee Whiz" is from www.lightreading.com - a news items concerning how Alcatel has passed the greatest number of bits per second through a single optical fiber. Each channel is a different wavelength (frequency) of light - sort of a different color as it were. And do not forget, a single optical fiber has a diameter of only a few red blood cells, much finer than a human hair. Here is the reference and a couple of quotes:

lightreading.com

"The company has achieved a unidirectional transmission of 128 channels each modulated at 40Gbit/s, reaching a total throughput of 5.12Tbit/s (5,120Gbit/s) over 300 km."

"With this 5.12Tbit/s achievement, Alcatel paves the way towards 10Tbit/s transmission on a single optical fiber, thus offering its customers perspectives for unprecedented capacities and services at the lowest cost."

5Tbit/s is about 60 10 GigaByte disk drives worth of data every second through a single, microscopic, 200 mile long glass fiber! It is certainly a Brave New World out there, isn't it.
