Fibre optic cables are very different from copper ones. Developed from the 1960s, they carry pulses of light, not electrical signals, and have no need for a second cable for a 'return path'.
They can transport much greater amounts of information, and also, on a mile-for-mile basis, they are much less 'noisy' than copper and as a result lose much less information.
Fibre optic cables are increasingly replacing copper cables as the backbone of today's telecommunications network and have played a huge part in making the internet available around the world.
