The speed of light through fibre or copper is significantly less than the speed of light in a vacuum - the refractive index is different. However, as far as the speed of light through fibre and copper are concerned, I believe that they are broadly comparable - but I doubt that they are identical. The speed of light depends on the medium it travels through - try sticking a spoon in a glass of water.
