World's fastest internet speed downloads whole Netflix in 1 second
Scientists from University College London in UK have achieved a data transmission rat of 178 terabits per second, it is five times faster than the previous record.
The researchers have claimed that it is world's fastest internet data transmission rate. At this speed, it is possible to download the entire Netflix library in less than a second.
The record, described in a research paper published in the journal IEEE Photonics Technology Letters, is double the capacity of any system currently deployed in the world.
It was achieved by transmitting data through a much wider range of colors of light, or wavelengths, than is typically used in optical fibre, the researchers informed.
They combined different amplifier technologies needed to boost the signal power over this wider bandwidth and maximized speed by developing new Geometric Shaping (GS) constellations, manipulating the properties of each individual wavelength.
GS constellations are patterns of signal combinations that make best use of the phase, brightness and polarization properties of the light.
The scientists said, "The benefit of the technique is that it can be deployed on already existing infrastructure cost-effectively, by upgrading the amplifiers that are located on optical fibre routes at 40-100 km intervals." adding, "the new record, demonstrated in a lab, is a fifth faster than the previous world record held by a team in Japan."
They also claimed that at this speed, it would take less than an hour to download the data that made up the world's first image of a black hole.
"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," said lead author Lidia Galdino, a Lecturer at UCL and a Royal Academy of Engineering Research Fellow.

These technologies make better use of optical fibre bandwidth, enabling a world record transmission rate of 178 terabits a second, Galdino added.
