Siemens Reaches 107 Gbps Data Transfer Record 161
prostoalex writes "Reuters is reporting on Siemens engineers reaching 107 Gbps data transmission record over a fiberoptic cable, and expects the technology to be on the market within a few years: "The test, 2.5 times faster than a previous maximum transmission performance per channel, was done in cooperation with Germany's Micram Microelectronic, the Fraunhofer Institute for Telecommunications and Eindhoven Technical University of the Netherlands.""
Fiber is Great but quite expensive still (Score:2, Interesting)
We run multiple cat6 cables as trunk links between our switches just because there are more ports to do so and it is cheaper to do those runs.
How viable is it over longer distances? (Score:2, Interesting)
From the article:
After 100 miles, how much does the throughput degrade? The technology might be limited if, after 200, 500, or even 1000 miles, its speed drops significantly. Or does it reach a hub of some sort that re-sends the signal every 100 miles? I should admit now that I'm not very familiar with how large telecom networks are set up.

a general standard in the industry is in the order of 30mi of fiber before signal regeneration is necessary. This is a main reason why the US is not very well suited to fiber octics transmissions in the way a smaller countries like germany or netherlands are. It's not the cost of running fiber, but the cost of maintaining sites and equipment to provide a long distance (cross-country?) signal.
Technology anyone? (Score:2, Interesting)
fast photodiodes
fast multiplexers
GaAs-transistors
fibre amplifiers (this is for the post about connecting continents)
?
They say they do it electrically, so they need to have a photodiode with 200 GHz bandwidht,
compare that with the diode in your DVD!
