Researchers have set a new world record for data transfer, helping to usher in the next generation of high-speed network technology. They transferred data in opposite directions at a combined rate of 186 gigabits per second (Gbps) in a wide-area network circuit. The rate is equivalent to moving two million gigabytes per day, fast enough to transfer nearly 100,000 full Blu-ray disks — each with a complete movie and all the extras — in a day.
