Fiber-optic cable is made in an almost incomprehensibly precise way


Fiber-optic cable is made in an almost incomprehensibly precise way. It has to be so pure, so clear, that it can transmit light over many dozens of miles without any boosting or encouragement, and without losing any of the information that has been encoded onto that light. To get that clarity, its manufacturers control every micron and every second of the manufacturing process.

The history of fiber optics goes back to the 1960s, with the invention of the laser. Lasers apply energy to billions of atoms, exciting their electrons and making them emit photons that then turn around and make already-excited atoms give off even more photons.
