As the saying goes, one strand of optical fiber is about the diameter of a human hair.CORNING
It’s an amazing idea. Now, copper wires—sometimes called “twisted pair” because they are made of pairs of strands of copper twisted around one another—also carry data and telephone signals to homes and farms in much of rural America.
But because of the characteristics of copper as a transmission medium, signals that travel over copper doesn’t have the extraordinary frequency range that light signals do, are subject to interference from other signals, and in general, degrade very quickly over more than a short distance.
That’s why if you have a copper-wire DSL (digital subscriber line) subscription, you have to be very close to the phone company’s “central office” to get a download signal into your house. A DSL house is connected to a copper wire, not a fiber-optic cable.

Not only can light travel over fiber for hundreds of miles with little attenuation (impossible with copper), but signals zipping around via fiber don’t get interfered with by other electrical transmissions nearby (which happens all the time with copper). Fiber is also, once it’s installed, far cheaper to maintain than a copper line.
As Mazzali explained, the traditional ways of making glass—blowing and pressing melted silica, for example—create a bubble-filled, flawed product that can’t do what Maurer’s team required. “Because you need purity and transparency,” he said, “you cannot start from sand or anything like that and melt it and make glass.”
