New record for bandwidth capacity over an optical link, 03/26/09. Researchers from AT&T, NEC, and Corning transmitted data at 114 Gigabits per second on each of 320 separate optical channels over a 580-kilometer link. Bandwidth capacity totaled 32 Terabits per second, beating the previous recording-setting mark (in 2008) by 25% while more than doubling the distance of the previous record. The optical link used Corning® SMF-28® ULL fiber, which is ITU G.652-compliant.

To reach this benchmark, the team generated and received signals using new methods engineered to reduce the interference resulting from operating at 320 wavelengths over a single line.

This record represents an advance in the development of 100-Gigabit technologies, which are considered crucial for handling Internet traffic demands in the future. And because amplification was done using existing optical amplifiers, the transmission also demonstrated the compatibility of the new transport capacities with the amplifiers in use today.
