Light-beam 'twins' take data farther

[DrLeftover]

An idea similar to that of noise-cancelling headphones has proved useful in increasing the data-carrying properties of light.

Researchers reporting in Nature Photonics suggest putting not one beam of light down a fibre, but a pair, each a kind of mirror image of the other.

When recombined on the receiving end, the noise that the signals gather in the fibre cancels out.

These paired beams can travel four times farther than a single one.

Excellent. Now if they could actually get fibreglass everywhere...
