UCL researchers double fibre optic distances

Antony Savvas | Feb. 4, 2015
The new method has the potential to reduce the costs of long-distance optical fibre communications as signals wouldn't need to be electronically boosted on their journey, which is important when the cables are buried underground or at the bottom of the ocean.

Study author professor Polina Bayvel, also of UCL Electronic & Electrical Engineering, said: "We're excited to report such an important finding that will improve fibre optic communications. Our method greatly improves the efficiency of transmission of data - almost doubling the transmission distances that can be achieved, with the potential to make significant savings over current state-of-the art commercial systems."

She said: "One of the biggest global challenges we face is how to maintain communications with demand for the internet booming - overcoming the capacity limits of optical fibres cables is a large part of solving that problem."
