Generally, fiber optic cables are wires that transmit data through an extremely thin layer of glass or plastic threads. These threads are the actual fibers in a fiber optic cable. The relationship to LI-FI technology is in the regard that data travels through the fiber in the form of light which is then translated into 1's and 0's, the data part. One of the key advantages to using light as a data transmitter is its massive bandwidth which is what makes fiber optics popular today. However, fiber optics are notoriously expensive but may soon replace most existing traditional metal cables.

Ever since getting Verizon Fios, I found my internet to be much faster than it was before. Agreeably it is more expensive, but there is no question of the much greater speed and bandwidth it makes up for.
