According to wikipedia, electric field propagation through unshielded copper is 0.95c to 0.97c. Electric field propagation through standard coaxial cable is 0.66c.

Hence why zmmmmm was incorrect about the speeds: electricity in the copper wires is travelling faster than light in the fibre optic cables. zmmmmm didn't mention drift velocity, but that wasn't really related to his point.
