Working with two companies, Xtera and KDDI Research, the research team led by Dr Lidia Galdino (UCL Electronic & Electrical Engineering), achieved a data transmission rate of 178 terabits a second (178,000,000 megabits a second) – a speed at which it would be possible to download the entire Netflix library in less than a second.

The record, which is double the capacity of any system currently deployed in the world, was achieved by transmitting data through a much wider range of colours of light, or wavelengths, than is typically used in optical fibre. (Current infrastructure uses a limited spectrum bandwidth of 4.5THz, with 9THz commercial bandwidth systems entering the market, whereas the researchers used a bandwidth of 16.8THz.)

UCL engineers set new world record internet speed

The world’s fastest data transmission rate has been achieved by a team of UCL engineers who reached an internet speed a fifth faster than the previous record.

I wonder what's the use of such high transmission rates without means to record the transmitted data at a similar speed. It would require tremendous buffers unless there is some new data recording technology I don't know about.

Technically if you don't split the fiber cable you might get similar speed but isps don't care about you only revenue

There is still no sense for this transmission sped if the fastest storage devices can't reach 1% of it. The only reason would be to split the data stream to multiple users and may lead to higher speed and cheaper connections in the future.
