A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. It is used for hubs and switches to communicate at very high speed.
Fiber optic cables have a much greater bandwidth than metal cables - this means that they can carry more data
Fiber optic cables are less susceptible than metal cables to interference
Fiber optic cables are much thinner and lighter than metal wires
Data can be transmitted digitally (the natural form for computer data) rather than analogically
