Telephone wires can pick up external interference and their electrical resistance means frequent repeater stations are needed. Optical fibres don't have these problems and can carry much more information due to the high frequency of light compared to wire-born electrical currents. Lasers and new methods of preparing glass fibres make the technology practical now.
