New world record for undersea data transmission

The experiment leveraged Bell Labs’ pioneering work in 200Gbps single carrier data channels. At such speeds and distances signal distortions and noise make data recovery challenging. To counter the problem, in this new test Bell Labs researchers made use of new detection techniques and harnessed an array of technologies in modulation, transmission, and external link signal processing, twinned with advanced error correcting coding.

Alcatel-Lucent has createda new record for the amount of data transmitted over transoceanic distances on a single optical fiber. In a test carried out at Alcatel-Lucent’s Innovation City campus in Villarceaux near Paris, researchers from Bell Labs successfully sent data at speeds of 31Tbps over 7,200km – a capacity said to exceed that of the most advanced commercial undersea cables by a factor of three. This was achieved with a span of 100km – the distance between amplifiers maintaining the entire length.
