Huawei Achieves 1 Terabits Per Second Speeds

Chinese networking giant Huawei, in partnership with telecoms company Proximus, have achieved unbelievable speeds of up to one terabits per second over super-channel optical cable, the equivalent of sending 33 HD movies in just a second. The successful trial was announced on Huawei’s website on Thursday.

The record-breaking transmission, held in Nice, France, involved sending data over 1,040km fibre connection, implementing a ‘Flexigrid’ infrastructure and Huawei’s own OSN (Optical Switch Node) 9800 platform and 1Tbps OTN (Optical Transport Network) line card, increasing the capacity of the fibre optic cable by compressing the spaces between the transmission channels. The increased density within the cable marks a 150% rise in efficiency over typical 100GBps network connections.

“The network is turning to DC (Data Center) centric, which brings a boost demand for increased bandwidth,” said Jeffrey Gao, President of the Huawei transmission network product line. “Businesses are currently undergoing a digital transformation and consumers require always-on connectivity. Huawei supports its customers through innovation; together we build simplified networks ensuring the best user experience towards end users. This trial is testimony of Huawei’s engagement to innovation.”

“At Proximus we pledge to satisfy the evolving customers demand by investing in new technologies to offer them the best quality and service,” Geert Standaert, Chief Technology Officer at Proximus, added. “Together with Huawei we want to let our network infrastructure evolve to support current and future bandwidth demands and offer our customers an outstanding user experience.”

New Fibre Technology – 1TB Transferred in 3 millieconds

Do you remember when 10 megabit networks were the crux of our networking technology? Transferring your 500mb back-ups over from one computer to another took an age, let alone downloading something large off the internet.

Once again, in comes science to save the day. Researchers from the University of Central Florida and the Eindhoven University of Technology have put their heads together to create a new breed of fiber networking – allowing for up to 255 terabits per second delivery speeds.

Broken down, what do these speeds mean in real-life circumstances? If you’re looking to transfer a high quality 2GB movie file, you’re looking at a lengthy wait of 0.06 milliseconds and a backup of your whole personal photo and movie collection from your family holidays will set you back 31 milliseconds of your precious time. Comparing this to the current 100Gbps offered by fiber on offer, this new technology offers you a 2550 times increase in overall speed.

Unfortunately this blisteringly fast speed is going to be currently capped by the limitations of our network cards, hard drives and solid state devices – but now the technology is there and reachable, there’s no knowing what is going to come out next.

It works by utilizing glass fiber split up into seven different cores arranged in a hexagon pattern. Techspot went into further detail, explaining: “By using spatial multiplexing, they were able to achieve speeds of 5.1 terabits per carrier and wavelength division multiplexing (WDM) to push 50 carriers down the cores. All said and done, it equaled the magic 255 terabits per second.”

Here’s hoping that sometime in the foreseeable future we can see global internet speeds transcending 100Gbps speeds, making loading times a thing of the past.

A man can dream! But for the moment, this technology is actually faster than the total capacity of every glass fiber cable lining the Atlantic Ocean – which currently number in the hundreds.

Graphene antennas will allow Terabit per second uploads

Researchers at Georgia Tech have made plans to build a wireless antenna using atom-thin sheets of carbon/graphene which will have the potential to allow terabit-per-second transfer speeds at short ranges.

In theory, in short range you can move as much as 100 terabits per second which will approximately allow you to transfer about 100 high definition movies within minutes.

Ian Skyildiz, director of broadband wireless networking laboratory at Georgia Tech said,”“It’s a gigantic volume of bandwidth. Nowadays, if you try to copy everything from one computer to another wirelessly, it takes hours. If you have this, you can do everything in one second—boom!!”

Using the graphene antenna, it is possible to have terabit-per-second upload at the range of one meter for now. Graphene is a sheet made of carbon which is only 1 atom thick and is of a honeycomb structure which have many desirable electronic properties as the electrons are able to move through graphene with no resistance, therefore making it 50 to 500 times more faster than what’s possible using silicon.

To make the antenna, the sheet of graphene could be shaped into narrow strips with the width between 10 to 100 nanometers and 1 micrometer long. This will allow the material to transmit and receive terahertz frequency. The electromagnetic waves in the terahertz frequency will be in contact with oscillations of electronics at the surface of the strip, achieving the ability to send and receive information.

Graphene antennas don’t allow such high upload independently as they rely on many other components to do so, such as signal generators and detectors, amplifiers, and filters. The researchers also need to figure out how to mass produce this as working with material is extremely tricky as its properties changes when it comes in contact with other materials.

As one would expect, Georgia tech hopes that the prototype of the antenna within a year.

It was during MWC 2013 where Samsung said that they will be funding the research for intra-chip communication using a terahertz band. In their Global outreach program, Samsung said that they will give $120,000 to team of research from Universitat Politechnica de Catalunya-Barcelona Tech and the Georgia Institute of Technology.
