Fibre-optic cables carry groups of photons to represent data, and huge numbers of these groups can be sent along the line one after another without waiting for the first to arrive. He and his colleagues say that their findings may allow houses near fibre-optic cables to achieve higher speeds than they currently enjoy without the expense of running fibre all the way to their home. "These cables are actually very old, invented by Alexander Graham Bell, and since then no one has looked into the theoretical limits," says Dinc. Above that limit, the researchers found that the wire essentially acts as an aerial and transforms any signal sent along it into radio waves that dissipate before reaching their destination. Ergin Dinc at the University of Cambridge and his colleagues say that twisted pairs of copper wire, of the type used for decades as telephone lines and now repurposed for broadband internet, can support a frequency fives times higher than is currently used, which would dramatically improve data transmission rates. New Scientist: Their technique to boost speeds may help to ease the transition to nationwide fibre optic, and may also be of use in countries that use similar twisted-pair copper wire. The company and the SEC said the deal should provide a roadmap for other companies.įibre-optic cable is being laid across the globe at great expense to speed up people's internet connections, but researchers claim that the copper telephone wire already in use across the country can achieve data rates three times higher than currently seen at a fraction of the price, at least over short distances. BlockFi plans to offer an alternative yield product, which it said it would register first. That effort might set them up for a clash with the agency as it increases scrutiny of the crypto industry. Most firms have tried to structure the interest-bearing products to avoid the need to register them with the SEC, a process that takes time and entails ongoing disclosure and reporting obligations. Still, many digital asset companies providing such products said this month the rules remain unclear to them and they are uncertain when they should register such offerings, which are growing more popular and which many firms launched within the last year. Securities and Exchange Commission and state authorities who said its interest-bearing product qualifies as a security and should have been registered. From a report: In February, New Jersey crypto company BlockFi agreed to pay $100 million in a landmark settlement with the U.S. regulations governing products that allow customers to earn interest on holdings instead of trading them, months after such an interest-bearing product drew a $100 million fine from a federal regulator and state governments.
