New internet data transmission speed record: this is how these UCL engineers have achieved as society advances and technology with it. What seemed impossible yesterday, today is not.

The research team headed by dr Lidia Galdino, professor of Engineering, Electronic and Electrical, University College of London (UCL) and a research fellow of the Royal Academy of Engineering, along with two companies, Xtera and KDDI Research, have managed to beat one of those records that seem impossible in a laboratory at the UCL, the speed of transmission of data, getting to be a fifth faster than the previous record, which belonged to a japanese team.

As described in a new article by IEEE Photonics technology Letters, it reached a speed of 178 terabits per second, or what is the same, 178,000,000 megabits per second, twice the capacity of today's systems.

"While current state-of-the-art cloud data center interconnections are capable of transporting up to 35 terabits per second, we are working with new technologies that make more efficient use of existing infrastructure, making better use of fiber optic bandwidth and enabling a world-record transmission rate of 178 terabits per second," explains the project's lead author and researcher, Dr. Galdino.

To give you an idea of how fast this transmission is, you could download all the Netflix series and movies in just a second, and it would even take less than an hour to download the data from the first image taken from a black hole that, due to its size, was stored on half a ton of hard drives and transported by plane.

This fast data transmission has been achieved thanks to a wider range of light colors or wavelengths than the well-known optical fiber.

The spectrum bandwidth currently used is 4.5 THz, while these engineers used a much larger bandwidth of about 16.8 THz.

However, the process has not been easy. To achieve this significant amplification, researchers have had to combine different technologies, thus creating new constellations of geometric conformation (GS), which managed to modify the properties of each wavelength individually and make better use of their properties.

In addition, this represents a major advance in the world of telecommunications, as with the current coronavirus crisis, the demand for these services has seen increases of up to 60% compared to the pre-pandemic period, in terms of data traffic.

“But, regardless of the COVID-19 crisis, internet traffic has increased exponentially over the past 10 years and all this growth in data demand is related to the decrease in cost per bit," explains the doctor. "The development of new technologies is crucial to maintain this trend towards lower costs while meeting future demands for data speed that will continue to increase, with applications that are still unthinkable that will transform people's lives."

Another benefit of this technique is that it can be used in existing infrastructures without too high a cost, as it is enough to update the fiber optic amplifiers at intervals of 40-100 kilometers.

The upgrade would involve a much lower cost than installing new optical fibers, as this could cost 500,000 euros per kilometre and fiber, while maintaining them would cost about 18,000 euros each.

Such have been the restrictions on Huawei that the US has adopted in the past year, and why these vetoes could push for a new escalation of the trade war with China

The Trump administration's vetoes and impediments to Huawei have been constant over the past two years. The last has been to include 38 companies in the list of companies that can not buy electronic components from US firms so that they do not provide chips to Huawei, it may be the drop that fills the glass.

Several analysts consulted by CNBC warned: the Chinese smartphone and telecommunications manufacturer would have received a deadly blow. Its CEO for the Consumer division, Richard Yu, admitted a few days ago that in September Huawei would cease the production of its Kirin chips, which until now assembled in its most powerful mobile.

Now, according to Bloomberg, the constant US vetoes on Huawei would be causing the trade war between the Western Power and China to escalate again. The economic medium reviews what the US 'attacks' on Huawei have been over the past few months before warning that China might be ready to respond.

In fact, Beijing admitted this Thursday that it would safeguard" the legitimate interests "of its domestic companies while regretting that the US based its decisions alluding to" national security "without"factual basis". It was collected by Europa Press in this information.

The Chinese authorities ' reaction came after U.S. restrictions also gave Huawei the jump to other Asian companies, such as ByteDance, owner of TikTok —which will have to stop operating in the U.S. in September if it does not sell its operations in the country to a U.S. firm earlier. Have already positioned online auction firms such as Microsoft, Twitter and Oracle.

Also Tencent, the giant behind the popular messaging app WeChat that has investments in global phenomena like Epic Games-the studio behind Fortnite - or Riot Games-League of Legends—.

In a recent article, Bloomberg goes back to Donald Trump's decision last May to begin demanding a license from U.S. companies selling electronic components to Huawei.

When the move was taken, the Chinese brand reacted by asserting that the decision was in response to Huawei threatening the" technological hegemony " of the US.

But simultaneously, the U.S. government decided to extend a measure that was adopted in mid-2019: to include Huawei on the Entity List, a blacklist by which U.S. companies would no longer be able to do business with the Asian firm.

The inclusion of Huawei in the famous US blacklist is the reason why Google stopped providing its services on the company's latest terminals. In other words: although Android is a free operating system, Google's Android that sees most terminals on the market includes a number of services, such as the Play Store which is the App Store, Maps, Gmail or YouTube.

Huawei's new phones could not access these services, which is why the Chinese firm has been looking for alternatives incessantly over the past few months.

In May, the US government decided to extend the legal framework allowing Huawei to be included in the list for another year. During these months, the inclusion of Huawei in The Blacklist has not been entirely effective: it has been going through several extensions since many internet providers in the rural area of the United States had not been able to get rid of Huawei equipment in the installation of their networks.

Beyond these measures, the US has been pressing its partners and other Western countries to prevent Huawei stations from being present in their new 5G networks.

A priori, he was not heard. The European Union left the ball on the roof of the member countries to decide who would be the suppliers of equipment for their 5G networks, although it suggested that in the 'critical' area of the new infrastructure there were no risk actors.

The US has been systematically denouncing for months that Huawei is the gateway to the networks of Western countries for Chinese intelligence services. However, these accusations have never been accompanied by evidence or too much substantiation.

At first, even UK Prime Minister Boris Johnson ignored Trump's warnings and decided to allow Huawei to enter the country'S 5G infrastructure and networks. However, Johnson's government stepped down a few weeks ago due to pressure from a group of MPs from his party.

Countries like France have also chosen to keep Huawei away from its 5G networks. Spain, meanwhile, believes that the stations designed by the Chinese firm meet the security standards that are demanded in the industry.

If Huawei's 5G vetoes and the company's inclusion on the Entity List were not enough, the Trump administration began demanding a license from U.S. companies last May if they wanted to continue selling them electronic components. These components are what the brand used to produce its own semiconductors.

A new step has now been known this week: to prevent Huawei from buying the chips from other non-US companies that did use American components, the US government has included 38 companies working with Huawei in these licensing requirements.

All this, added to the controversy by TikTok in the US, Opens the door to rethink the scenario reached after the agreement between the United States and China to reduce the tension that caused their trade war.

According to Bloomberg, talks between the two powers remain stalled, and it was Trump himself this week who assured that the order by which US officials would stop negotiating with the Chinese was given by him. The media also recalls that the Chinese economy is the fastest emerging from the COVID-19 crisis.
