Researchers at Deutsche Telekom's T-Labs have blasted bits at impressive velocity down a single optical fiber, breaking the previous long-distance data-transfer record by more than a factor of two. The bit boffins achieved a 512 gigabits-per-second transmission rate over a single optical fiber from Berlin to Hanover and back, a distance of 734 kilometers. Subtracting out the error-correction overhead, the total usable bandwidth was 400Gb/s – enough, T-labs points out, to transmit a stream of data equivalent to 77 music CDs in one second.
