Light propagates most efficiently in a vacuum, (eg an absent of matter). The propagation of light is slowed down when it travel through matter, for example, water slows down the speed of propagation; although, I guess, light itself always travels at its constant speed. The increase speed in transmitting data is due to new techniques that allow each fiber optic cable, which is about the size of a human hair, more bandwidth. Efforts are under way to further increase the bandwidth of each fiber optic cable in a backbone line by a factor to 10, over the original method used. To achieve this 10 fold increase will require new fiber optic lines, I believe, while the increase by 4 works fine over the original fiber optic cables.
