Researchers claim to set new world record for internet speed.

On August 24, scientists in the UK claim they have achieved the worlds fastest internet data transmission rate, a speed which would make it possible to download the entire Netflix library in less than a second. The researchers from University College London in UK achieved a data transmission rate of 178 terabits a second which is five times faster than the previous record.

The researchers said, 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.

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.

Researchers mentioned, 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.

They said, at this speed it would take less than an hour to download the data that made up the worlds first image of a black hole. The speed is close to the theoretical limit of data transmission set out by American mathematician Claude Shannon in 1949.

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