Scientists claim to have developed a new laser technology capable of delivering 26Tb data transfer speeds.
Fibre-optic experts working at the Karlsruhe Institute of Technology successfully transferred data down a 50km single-mode cable.
The achievement could pave the way for new ultra-fast broadband innovations, potentially allowing wider access to high download speeds in the future.
Professor Ben Eggleton, Director of the Centre for Ultrahigh bandwidth Devices for Optical Systems (CUDOS), said the real breakthrough was in the fact that a single laser had been used to deliver the data.
"It's a simple optical technique that's enabled the generation of this enormous amount of data in this conventional optical fibre," he explained.
"Increase in the capacity of the backbone is basically doubling every 18 months, because we're using the internet more frequently and we're using more sophisticated tools."
Professor Eggleton suggested that with broadband data consumption continuing to increase, it is vital to develop new technologies capable of meeting user demand.
