As IT updates go, this was about as nerve-wracking as things can get.<\/b><\/p>\n

In February, deep inside a warehouse at Cern, the Swiss home of the Large Hadron Collider (LHC)<\/a> \u2013 the world\u2019s biggest science experiment \u2013 two network engineers held their breath. And pressed a button.<\/p>\n

Suddenly, text on a black background flashed up on a screen in front of them. It had worked. \u201cThere was high-fiving involved,\u201d recalls Joachim Opdenakker at SURF, a Dutch IT association that works for educational and research institutions. \u201cIt was super-cool to see.\u201d<\/p>\n

He and his colleague Edwin Verheul had just set up a new data link between the LHC in Switzerland and data storage sites in The Netherlands.<\/p>\n

A data link that could reach speeds of 800 gigabits per second (Gbps) \u2013 or more than 11,000 times the average UK home broadband speed<\/a>. The idea is to improve scientists\u2019 access to the results of LHC experiments.<\/p>\n

A subsequent test in March using special equipment on loan from Nokia proved the desired speeds were achievable.<\/p>\n

\u201cThis transponder that Nokia uses, it\u2019s like a celebrity,\u201d says Mr Verheul, explaining how the kit is booked up for use at various locations in advance. \u201cWe had limited time to do tests. If you have to postpone a week, then the transponder is gone.\u201d<\/p>\n

This amount of bandwidth, approaching one terabit per second, is extremely fast but some subsea cables are a few hundred times faster still<\/a> \u2013 they use multiple fibre strands to achieve such speeds.<\/p>\n<\/div>\n

After its upgrade the Large Hadron Collider will produce five times as much data<\/figcaption><\/p>\n<\/figure>\n

In labs around the world, networking experts are coming up with fibre optic systems capable of pushing data around even more rapidly than this. They are reaching extraordinary speeds of many petabits per second (Pbps), or 300 million times the average UK home broadband connection.<\/p>\n

This is so fast that one can barely imagine how people will use such bandwidth in the future. But engineers are wasting no time in proving that it is possible. And they only want to go faster.<\/p>\n

The duplex cable (with cores that either send or receive) from Cern to data centres in The Netherlands is just shy of 1,650km (I,025 miles) long, snaking from Geneva to Paris, then Brussels, and finally Amsterdam. Part of the challenge in reaching 800 Gbps was in beaming pulses of light such a long way. \u201cDue to the distance, the power levels of that light decrease, so you have to amplify it at different locations,\u201d explains Mr Opdenakker.<\/p>\n

Every time one tiny subatomic particle smashes into another during experiments at the LHC, the impact generates staggering volumes of data \u2013 about one petabyte per second<\/a>. That\u2019s enough to fill 220,000 DVDs.<\/p>\n

This is slimmed down for storage and study, but still requires hefty amounts of bandwidth. Plus, with an upgrade due by 2029, the LHC expects to produce even more scientific data than it does today<\/a>.<\/p>\n

\u201cThe upgrade increases the number of collisions by at least a factor of five,\u201d says James Watt, senior vice president and general manager of optical networks at Nokia.<\/p>\n<\/div>\n

\n

A time when 800 Gbps seems slow may not be far away, however. In November, a team of researchers in Japan broke the world speed record for data transmission when they reached an astonishing 22.9 Pbps. That\u2019s enough bandwidth to supply every single person on the planet, and then a couple billion more, with a Netflix stream, says Chigo Okonkwo at Eindhoven University of Technology, who was involved in the work.<\/p>\n

In this case, a meaningless but huge stream of pseudorandom data was beamed over 13km of coiled fibre optic cable in a lab setting. Dr Okonkwo explains that the integrity of the data is analysed post-transfer to confirm it was sent as quickly as reported without accumulating too many errors.<\/p>\n

He also adds that the system he and colleagues used relied on multiple cores \u2013 a total of 19 cores inside one fibre cable. This is a new type of cable unlike the standard ones that connect many people\u2019s home to the internet.<\/p>\n<\/div>\n

But older fibre is expensive to dig up and replace. Extending its lifetime is useful, argues Wladek Forysiak at Aston University in the UK. He and colleagues have recently achieved speeds of around 402 terabits per second (Tbps) along a 50km-long optical fibre with just one core. That\u2019s about 5.7 million times faster than the average UK home broadband connection.<\/p>\n

\u201cI think it\u2019s a world best, we don\u2019t know of any results that are better than that,\u201d says Prof Forysiak. Their technique relies on using more wavelengths of light than usual when flashing data down an optical line.<\/p>\n

For this they use alternative forms of the electronic equipment that sends and receives signals over fibre optic cables but such a setup could be easier to install than replacing thousands of kilometres of the cable itself.<\/p>\n

Activities in the so-called metaverse<\/a> might one day require extreme bandwidth, suggests Martin Creaner, director general of the World Broadband Association. His organisation expects home broadband connections to reach up to 50 Gbps by 2030<\/a>.<\/p>\n

But reliability may be even more important than speed for some applications. \u201cFor remote robotic surgery across 3,000 miles\u2026 you absolutely do not want any scenario where the network goes down,\u201d says Mr Creaner.<\/p>\n

Dr Okonkwo adds that training AI will increasingly require moving huge datasets around. The faster this can be done, the better, he argues.<\/p>\n

And Ian Phillips, who works alongside Prof Forysiak, says bandwidth tends to find applications once it is available: \u201cHumanity finds a way of consuming it.\u201d<\/p>\n<\/div>\n

Demand for bandwidth is growing surprisingly fast says Lane Burdette<\/figcaption><\/p>\n<\/figure>\n
\n

Although multiple petabits per second is far beyond what today\u2019s web users need, Lane Burdette, research analyst at TeleGeography, a telecoms market research firm, says it is striking how quickly demand for bandwidth is growing \u2013 currently, at around 30% year-on-year on transatlantic fibre optic cables.<\/p>\n

Content provision \u2013 social media, cloud services, video streaming \u2013 is eating up far more bandwidth than before, she notes: \u201cIt used to be like 15% of international bandwidth in the early 2010\u2019s. Now it\u2019s up to three quarters, 75%. It\u2019s absolutely massive.\u201d<\/p>\n

In the UK, there is still a long way to go to improve internet speeds. Many people cannot access sufficiently fast<\/a> broadband at home.<\/p>\n

Andrew Kernahan, head of public affairs at the Internet Service Providers Association says most home users can now access gigabit per second speeds.<\/p>\n

However, only about a third of broadband customers are signing up for such technology. There\u2019s no \u201ckiller app\u201d at the moment that really requires it, says Mr Kernahan. This might change as more and more TV is consumed via the internet, for example.<\/p>\n

\u201cThere\u2019s definitely a challenge to get the message out there and make people more aware of what they can do with the infrastructure,\u201d he says.<\/p>\n<\/div>\n<\/div>\n
