Researchers demonstrate 1.4 Tbps broadband connection using commercial-grade hardware

google fiber broadband internet connection

A joint research team from French telecoms Alcatel-Lucent and BT have come up with a 1.4 terabit connection that would put Google Fiber and all other competitors to shame. The technology is said to use commercial-grade hardware with a new protocol that allows for much faster data transfers.

The protocol is called Flexigrid and it allows multiple signals to be laid over top of each other within a single cable. In testing, researchers were able to layer seven 200 Gbps channels to create an “Alien Super Channel” with 1.4 Tbps speeds across some 255 miles of fiber that stretch from a BT research facility in Suffolk to a BT Tower in London.

Just how fast is 1.4 Tbps, you ask? Well, in terms of streaming, one could stream 64 hours of HD Netflix, 38 hours of Netflix in 3D or 4K or 36,409 songs – all within one second. Yeah, that is pretty darn quick.

The real benefit here is the fact that no new hardware is necessary – it’s all being done with a new protocol. In theory, it could be implemented on existing fiber that is already in the ground and give Internet providers a serious incentive to continue building fiber networks. Aside from Google, there really aren’t many companies laying fiber in the US as of writing.

Of course, with a connection speed that fast, you’d almost always be the bottleneck but hey, that’s a problem that I think most of us would be just fine with.

It's very impressive that all they had to improve it is by create a new protocol!
 
Well done but testing and real world conditions are totally different very much doubt you would see this through a telephone line or even cable but any reason to expand on fiber networks is good news :) never really understood the lack of investment into network backbone considering the amount of money that is paid to ISP's
 
Wonder if this will work on any network, or connection type (LAN, ethernet, wireless), because it might eliminate all bottlenecks altogether. How hard would it be to change the protocol though?

Would this be the entire UHD program list being broadcast within one fiber line?

Does 38 hours in 1 second not equate to over 120 thousand channels + 10% for overhead?
 
Amazing. One day this will be the norm :p
So that's a download speed of 1.25GB/s right?

What storage hardware can write data that fast? We will need to work on that too :)

No, 175 GBps or 175,000 MBps. The individual 200 GBps channels are more interesting to me as these would be more feasible for the current state of computer technology in terms of usable data rates (25 GBps or 25,000 MBps). Plenty of bandwidth for the reasonably foreseeable future, IMHO.
 
Damn, I had to look at the thread title again. For a minute I thought I was in Bill Gates 2034 Prediction thread. lol

..now, what we lack here is, we still at 4K resolution tech here, it's seems we need to go more.. say, streaming 16K for example. :D
