Fibre optic technology converts electrical signals carrying data to light and sends the light through very narrow transparent glass fibres. Fibre optic technology is more expensive than other broadband delivery.
Fibre optics provide extremely high bandwidth - no other cable-based data transmission medium offers the bandwidth that fibre does. It is easy to accomodate increasing bandwidth and it has a resistance to electromagnetic interference 0 it has a very low rate of bit error. It provides a secure transmission medium where cable damages can be detected early and there are secure transmissions.
The installation costs are still very high, despite the prices dropping. Special test equipment is often required - which are additional costs. Fibre optics are susceptible to physical damage since it is a small and compact cable, it can be cut or damaged. The cables can cause wildlife damage - to birds who peck at the fibre cable jackets.
Speed:
Similar to cable modem, fibre optic has speeds of up to 8 Mbps, 9.9 Mbps, 17Mbps and 30Mbps - it exceeds DSL or cable modem speeds.
