How is fibre optic different from what we currently use?

The main difference is that we currently connect via copper into people’s homes using ADSL technology. This mixes voice and data signals over the copper and then separates them via a modem inside the home. The problem with this is that the further away from the exchange a home is, the slower the speed. For example, using DSL technology beyond 4.5km, services faster than 1 Mbps cannot be reliably delivered. To reach speeds like 12 Mbps consumers need to be as close as 1.5km to the exchange.
