New Data Transmission Speed Record

An anonymous reader writes "Gizmag is reporting that a team of German and Japanese scientists have collaborated to shatter the world record for data transmission speed. From the article: "By transmitting a data signal at 2.56 terabits per second over a 160-kilometer link (equivalent to 2,560,000,000,000 bits per second or the contents of 60 DVDs) the researchers bettered the old record of 1.28 terabits per second held by a Japanese group. By comparison, the fastest high-speed links currently carry data at a maximum 40 Gbit/s, or around 50 times slower."

    A measurement everyone understands? Like how much porn?

  2. 60 DVD:s per second... by MadTinfoilHatter · · Score: 5, Funny

    ...and in related news, the spokesman for the MPAA is currently unable to comment due to suffering a heart attack.

    At 100Km/hour, a truck would require 1.6 hours * 60^2 seconds/hour = 5,760 seconds to travel 160 kilometers. At 60 DVDs/second, the truck would have to be carrying 5760*60 = 345,600 DVDs to have equivalent bandwidth. A typical DVD in a case is 14cm wide, 19cm tall, and 1.5cm thick, for a total volume of 399 cm^3 (lets round to 400cm^3). Therefore, the truck would have to have a cargo volume of 400cm^3 * 345,600 = 138,240,000cm^3, or 138.24m^3.

    Now, typical intermodal containers (as used on big rig trucks) are 8.5' by 8.5' by 40', or 2890ft^3. Converted to metric, this is about 82m^3, which is less than the 138.24m^3 required.

    In other words, no, a truck full of DVDs is NOT faster than this connection!*

    *unless you put the DVDs on spindles instead of in cases.
