Researchers at Eindhoven University of Technology in the Netherlands and the University of Central Florida managed to make a "multi-mode, multi-core" fiber cable, and make it more easily than anyone has in the past.
Basically, their cable uses wavelength division multiplexing to send multiple carriers down the same fiber. Then, the researchers combined seven fibers together in the same cable.
The upshot of that techobabble is that this super cable can carry 255 Terabits per second of data, or 255,000 gigabits. Remember, a regular fiber cable tops out at 100 gigabits.
To put that in perspective, a single super cable can carry more data than every other Internet cable in the world combined. And the test took place over a 0.62 mile cable, so long distances shouldn't be a problem.
Naturally, replacing current fiber with super fiber isn't going to happen overnight. In fact, it could take a decade or two to upgrade.
Still, it's nice to know this technology is ready to go when we need it.
