BT And Alcatel-Lucent’s Fiber Optic Tests Reveal 1.4 Tb/s Speeds

BT and Alcatel-Lucent have been reportedly working on a way to address the current internet speed bandwidth and congestions which some parts of the UK are facing. In an experiment performed, the companies managed to achieve a speed of 1.4 Tb/s over an existing fiber optic connection and commercial grade hardware, something which is the equivalent of transmitting 44 uncompressed HD films in one second.

The test has been performed from the BT Tower in London, all the way to a research campus located 255 miles away. The team has reportedly reached a speed of 5.7 bits/second/Hertz as part of a “Flexgrid” infrastructure, having a 50 GHz transmission channel rate and allowing a 42.5 percent data transmission efficiency compared to common fiber optic networks. But the best part still remains the means through which this has been achieved. Having the tests successful on the current fiber optic network means that ISPs will be able to deploy the new system without the need of additional physical cables, drastically reducing the costs.

The current broadband users will have no say in this, since the system requires at least fiber optic connection, though it will improve bandwidth for both broadband and fiber optic users. The discovery also has also opened some doors into the high-bandwidth Internet service required for heavy traffic, such as streaming high quality tracks and even 4K resolution videos in the future.

    So when can we expect to get something like this? If it can use existing hardware, surely it won’t be that hard to roll it out?

    The only issue I see is inside the home. Can existing routers, wired or wifi, keep up with this?

    (I get Fibre Optic in march where I live, wonder how long I’ll have to wait to get a terrabyte…)

    This could be good news for virus makers too. If you can download a terrabyte in a second, they could fill your drive faster than you can delete it effectively making your computer useless until you disconnect. I’m just rambling now though…
