London based team achieves the fastest internet speed of 178 Tbps

A team from University College London has achieved the fastest internet speed in the world. The earlier record was 172 terabits per second, achieved by the Japanese National Institute for Communications Technology earlier this year in April. It not only surpassed the previous best speed but by a huge margin attaining a speed of 178Tbps.

They were able to achieve this incredible speed by transmitting data through wider wavelengths normally used for optical fibre. Traditionally, 9 Terahertz (THz) has been used but the team used 16.8 Terahertz for the transmission.

Technically the implementation is cost-effective as it uses the same optical fibre used earlier, thus the same can be replicated anywhere with the present set of optical fibre. Only the amplifiers need to be changed for use of higher wavelengths.

“While current state-of-the-art cloud data-centre interconnections are capable of transporting up to 35 terabits a second, we are working with new technologies that utilize more efficiently the existing infrastructure, making better use of optical fibre bandwidth and enabling a world record transmission rate of 178 terabits a second,” said Dr Lidia Galdino, the lead author of the team.

He also added, “The development of new technologies is crucial to maintaining this trend towards lower costs while meeting future data rate demands that will continue to increase, with as yet unthought-of applications that will transform people's lives.”

For a better real-world perspective, with this speed, you can download the entire Netflix catalogue in less than a second. Although the attained speed is practically easy to implement, it will take time to hit consumer-level plans.
