UK Scientists Claim to Develop 2000 Times Faster Broadband via Fibre Optic

A team of scientists working out of Bangor University in Wales has developed a commercially affordable method of using Optical Orthogonal Frequency Division Multiplexing (OOFDM) over fibre optic lines, which could deliver broadband ISP speeds that are 2,000 times faster than current services.

But the three-year project (OCEAN) is not the first to make use of OOFDM, which typically splits a laser down to multiple different optical frequencies. The data can then be broken up and sent in parallel streams via the different frequencies. Last year a team of Sydney University scientists found an energy-efficient way of using a single laser to transfer data down a 50km long single-mode fibre optic cable at speeds of up to 26Tbps (Terabits per second).

The key difference with OCEAN is that this work is capable of “significantly saving the network installation and maintenance cost for both [ISPs] and equipment vendors” by using low-cost offthe-shelf components and end-to-end real-time OOFDM transceivers via currently installed fibre networks (FTTH etc.). It also provides a Green” solution due to the “significant reduction in electrical power consumption
