Researchers at Bell Laboratories claim to have set a world's record by transmitting 3.28 trillion bits of data per second over 300 kilometers of fiber optic cable.

The speeds were acheived using Lucent Technologies experimental optic fiber, TrueWave, in what was described as the industry's first demonstration of long distance, triple-terabit data transmission.

The experiment used DWDM, a technology that combines multiple wavelengths onto a single fiber, and distributed Raman amplification, a technique allowing optical fiber to amplify the signals traveling through it.
