Holy crap - that is fast!

From the Science and Core Technology Laboratory Group at Nippon Telegraph and Telephone Corporation. Take a two-hour HDTV movie and transmit it over a 52.4 km (32.5 mile) long 12-core optical fiber. Transmit the whole file in one second. Now transmit 4,999 other movies of the same file-size along with the first one. The article:
World Record One Petabit per Second Fiber Transmission over 50-km:
Equivalent to Sending 5,000 HDTV Videos per Second over a Single Fiber

NTT and three partners- Nippon Telegraph and Telephone Corporation (NTT, Chiyoda-ku, Tokyo, CEO: Hiroo Unoura), Fujikura Ltd. (Fujikura, Koto-ku, Tokyo, President and CEO Yoichi Nagahama), Hokkaido University (Sapporo, Hokkaido, President Hiroshi Saeki), and Technical University of Denmark (DTU, Lyngby, Denmark, President Anders Overgaard Bjarklev)-demonstrated ultra-large capacity transmission of 1 petabit (1000 terabit) per second over a 52.4 km length of 12-core (light paths) optical fiber.

The present achievement indicates that transmission of one petabit per second (Pbps), capacity equivalent to sending 5,000 HDTV videos of two hours in a single second is possible over 50 km, which is approximately the distance between medium-haul telecom offices. This sets a new world record throughput over a single strand of optical fiber.
Thinking about just the technology used to generate the test signal gives me a headache. It will take a year or so to get commercialized and rolled out but wow! Posted by DaveH at September 23, 2012 2:42 PM
