Paired Fibre Beams Boost Range and Speed of Fibre Networks to Colossal 400Gbps

By Gary Cutlack on at

Some clever research into boosting fibre optic speeds has managed to increase the range and capacity of fibre, thanks to sending two data streams down the pipe instead of one.

In a paper bewilderingly titledĀ Phase-conjugated twin waves for communication beyond the Kerr nonlinearity limit, researchers put forward their concept, which involves sending a pair of signals down a fibre connection, one a mirror of the other. When combined at the other end this allows the tech to better compensate for signal noise.

And thanks to the transmission requiring fewer error checks and less repetition of data, there's more available bandwidth to allow speeds to be pushed higher than ever and sent over distances four times as long as those managed by fibre networks today.

The test managed to beam data atĀ 400Gbps down a 12,800km link, to give you a rough idea of how quickly you may be able to fill a hard drive with pornography is some distant future world. [BBC]
