Thats around a 5th faster than the previous record, set by a team of researchers in Japan, and approximately twice as fast as the very best web readily available today.
With 4K films about 15GB in size, you could download about 1,500 of them in a single second at the new speed.
This could be more than just a super-fast lab experiment too– the technology utilized to reach the 178 Tbps record can be contributed to existing optical fiber pipelines relatively easily, according to the scientists behind the project.

Todays web is built on optical fibre routes that utilize amplifiers to stop the light signals from breaking down.
Adding the brand-new innovation to the existing amplifiers, spaced around 40-100 kilometres (25-62 miles) apart, would need a fraction of the expense that would be required to replace the real fibre, the researchers state.
” While present advanced cloud data-centre interconnections can carrying up to 35 terabits a 2nd, we are dealing with brand-new technologies that use more efficiently the existing facilities, making better use of optical fibre bandwidth and allowing a world record transmission rate of 178 terabits a second,” says electrical and electronic engineer Lidia Galdino, from University College London in the UK

If these upgrades can slot into existing infrastructure, a lot the much better.
Obviously with a worldwide pandemic requiring a lot of us to work and socialise throughout the internet instead of in person, the need for faster speeds and greater bandwidth has never been more topical– particularly with some 40 percent of the worlds population still yet to be linked.
” Independent of the COVID-19 crisis, web traffic has actually increased greatly over the last 10 years and this whole growth in data demand is connected to the cost per bit going down,” states Galdino.
” The advancement of brand-new technologies is essential to preserving this trend towards lower costs while meeting future information rate demands that will continue to increase, with as yet unthought-of applications that will transform peoples lives.”.
The research has been released in IEEE Photonics Technology Letters

To strike this record-breaking speed, the group used a much wider series of wavelengths (colours of light) than are typically used to send information.
The bespoke system used a bandwidth of 16.8 terahertz (THz) in a single-fibre core, 4 times the 4.5 THz used by most of our existing network facilities.
That bandwidth boost also needed a boost of signal power and several various amplifier strategies are integrated in this case.
The hybrid system manages the residential or commercial properties of each individual wavelength thoroughly, using a process called constellation shaping to optimise signal transmissions and prevent interference.
The mix of these methods indicated much more info might be packed into the exact same area and sent faster, without that details ending up being garbled along the method.
The new 178 Tbps record is pushing the theoretical limits of what an information transfer network can take.
This concept of squeezing more details through existing pipelines is one that numerous researchers are exploring, trying to strike the balance between getting information moved as photons of light quicker, without those photons hindering each other
The web has actually changed most locations of our lives over the last few decades, and the technology keeps enhancing: scientists just set a new record for information transmission rates, logging an extraordinary speed of 178 terabits per second (Tbps)
