Massive Bandwidth achieved

20th May 2016

could you handle 255Tbps - well thats what a research team in the Netherlands did !!

A joint collaboration consisting of a team dedicated researchers from the Netherlands and the USA have literally smashed the world "speed"/capacity record for a fibre network - a huge bandwidth of 255 terabits per second down a single strand of glass fibre. This is equivalent to around 32 terabytes per second! That would be enough to transfer a 1GB movie in 0.03 milliseconds, or alternatively, the entire contents of your 1TB hard drive in about 31 milliseconds.

To put 255Tbps into perspective, the fastest single-fibre links in commercial operation top out at a really slow pace of 100Gbps, or 2,550 times slower. 255Tbps is mindbogglingly quick; it’s greater, by far, than the total capacity of every cable — hundreds of glass fibres — currently spanning the Atlantic Ocean. In fact, 255 terabits per second is similar to — or maybe even more than — the total sum of all traffic flowing across the internet at peak time.

How did the researchers do it? Well......they used a multi-core fibre, of course! As it stands, it is often said that significant parts of the internet backbone consists of singlemode fibre. These SM fibres can only carry one mode of light — which, in essence, means they can only carry the light from a single laser.  Now we all know that we can carry multiple channels down a SM fibre using DWDM. but there are physical limits determined by of the laws of physics. So, this research could herald the dawn of the new age of hyper fibre, as it being dubbed.....
