Scientists develop new technology to boost internet speed

Scientists have developed new hardware that consistently provides high-speed broadband connectivity.

The new technology enables dedicated data rates at more than 10,000 megabits-per-second (Mb/s) for a truly super-fast, yet low-cost, broadband connection, researchers said.

“By 2025, average speeds over 100 times faster will be required to meet increased demands for bandwidth-hungry applications such as ultra-high definition video, online gaming, and the Internet of Things,” said Sezer Erkilinc, from University College London in the UK.

“The future growth in the number of mobile devices, coupled with the promise of 5G to enable new services via smart devices, means we are likely to experience bandwidth restrictions; our new optical receiver technology will help combat this problem,” said Erkilinc, lead researcher of the study published in Nature Communications.

Scientists, including those from the University of Cambridge in the UK, developed a simplified receiver to be used in optical access networks: the links connecting internet subscribers to their service providers.

“To maximise the capacity of optical fibre links, data is transmitted using different wavelengths, or colours, of light.Ideally, we’d dedicate a wavelength to each subscriber to avoid the bandwidth sharing between the users,” said Polina Bayvel, from UCL.

The new, simplified receiver retains many of the advantages of coherent receivers, but is simpler, cheaper, and smaller, requiring just a quarter of the detectors used in conventional receivers.
