Researchers upgrade fiber tech to transmit data at 255 Terabits/s

Researchers upgrade fiber tech to transmit data at 255 Terabits/s

Researchers at the Eindhoven University of Technology and the University of Central Florida have successfully transmitted data over a new type of fiber at a blistering speed of 255 Terabits per second.

The new fiber consists of 7 cores as supposed to the 1 core that standard, state-of-the-art, fibers currently carry. Furthermore, the researchers also implemented two additional "orthogonal dimensions" for data transmission, which is purportedly similar to having 3 cars driving on top of each other. These two methods in turn help to deliver 21 times more bandwidth than the 4-8 Terabits per second of current fiber technology.

Single-mode fibres with low loss and a large transmission bandwidth are a key enabler for long-haul high-speed optical communication and form the backbone of our information-driven society. However, we are on the verge of reaching the fundamental limit of single-mode fibre transmission capacity. Therefore, a new means to increase the transmission capacity of optical fibre is essential to avoid a capacity crunch. Here, by employing few-mode multicore fibre, compact three-dimensional waveguide multiplexers and energy-efficient frequency-domain multiple-input multiple-output equalization, we demonstrate the viability of spatial multiplexing to reach a data rate of 5.1 Tbit s−1 carrier−1 (net 4 Tbit s−1 carrier−1) on a single wavelength over a single fibre. Furthermore, by combining this approach with wavelength division multiplexing with 50 wavelength carriers on a dense 50 GHz grid, a gross transmission throughput of 255 Tbit s−1 (net 200 Tbit s−1) over a 1 km fibre link is achieved.

Nice. We won't see this technology again for another 50 years for any customer. What a shame :rolleyes:

Meanwhile in UK I am stuck with 10mb phone line connection with 1.4mb/s download speeds, and without any possible alternatives, even thou I have a willing and money to get something faster, but no. So annoying.

Be glad its not Verizon dsl in the states, some those places only get 3mbit and slower. and pay roughly the same for people that get 50+mbit, i so glad i left Verizon dsl for optimum i pay they same i was pay with Verizon dsl as i do for optimum cable only difference i actual get 120mbit.

Choice by me where DSL or Optimum and for 10+ years i tried to avoid cable isp, but 3mbit was no longer cutting it 100+month for dsl vs 100+ month for 100+mbit which would any sane person pick? lol.

I would love to see the 255terabits/s but when and if it does hit consumers they probably gona ask a arm/leg/hand etc for it too

Im stuck with the same in Canada but i also have a 100gb cap and its 70$ a month. its sad that in these countries we dont even have over 100mbps in most areas.

300kb/s here...
However I'm supposed to get 100mbit Q1 next year :banana:
