The Internet’s Physical Backbone is Maxing Out

The fiber-optic cables that transmit the internet’s data and direct its traffic have a power limit. For decades, researchers have been amplifying the signal passed through these cables to keep up with growing internet traffic. But those tricks won’t work forever: If you up the power beyond a certain point, the fibers becomes light-saturated and the signal degrades. And we’re very close to reaching that capacity limit, according to researchers who convened at a Royal Society meeting in London this week to discuss the matter. – Maddie Stone, Gizmodo
