What are the benefits of using fibre optics over copper?

Fibre provides more bandwidth than copper and has standardized performance up to 10 Gbps and beyond, something that it is impossible to achieve when using copper. More bandwidth means that fibre can carry more information with far greater efficiency than copper wire. Fibre does not radiate any signal and it is very difficult to tap, the only way to do so is by actually accessing the optical fibre itself which would be detected.

These properties are attractive to government bodies, banks and other institutions with major security concerns. Fibre is thinner, lighter and more durable than the equivalent copper cable. Its small size makes it easier to install and takes up less room in conduits and service ducts.
