Copper wires

It turned out that copper wires can provide Internet access at speeds up to 3 gigabits per second. The most common copper telephone wires are familiar to everyone who made the era of the early Internet. It was very slow, and until fiber came along, good internet speeds weren't available to the masses. However, scientists from Cambridge decided to test the capabilities of old copper cables. And they came to a funny conclusion - with a cheap revision, they can transfer data at gigabit speeds. And the funny thing is that, according to scientists, no one simply checked the potential of old cables - everyone simply switched to fiber optics and lost interest in improving existing lines.
