Fibre optics have several advantages over the conventional copper wire. First and foremost, it is cheaper to use fibre optics than it is to use copper wire. Fibre optics are also thinner and have a higher capacity for carrying data than copper wire. Optical fibres can be made smaller than any copper wire. This means that in a cable of the same size you can have more telephone lines or more TV channels feeding through, essentially it is a space saver. You have less signal los, less interference and lower power consumption when using fibre optics over copper wire. Lower power consumption means more money in your pocket. Fibre optics are also more flexible, weigh less and because no electricity passes through them they are non-flammable which makes them safer to use.
