Optic fibres have replaced conventional biaxial jelly filled telephone cable for the former`s advantage over the later for the speed and more accommodation of data sending.

FIOS, or fibre optic service is superior to regular phone or cable service. It is not only capably 'faster' in transmission, butr 'cleaner'.. I have worked with it in Television Broadcasting, and it is incredible. We did tests Coast to Coast with fibre optic next to a monitor and scope with regular cable, repeater transmission. The fibre optic signal was as clean as a signal sent from the next room, where the 'regular' feed was slightly degraded..(some noise and distortion.) When FIOS is working in your area, a converter is placed at your home, or on the telephone pole, to convert to your home use. Very little loss in this situation. Superior performance, and with FIOS, you can have TV, cable, phone, read your electric and water meters, with plenty of room left for expansion...

Glass fibers have coatings, also transparent. The refractive index between the two is such that the light will stay in the core of the fiber. The interface is like a mirror so long as the light hits the coating at an small enough angle.
It may not be faster in time. Light travels in a fiber at about 60% the speed of light in a vacuum. This is slower than most wire. Its big advantage is the signal can go very far. The signal in a fiber is modulated light pulses. These degrade slowly compared to wires. Also the light pulses can be put very close together so the message will be compressed into a shorter space and take less time so send. This will be faster rate even though the delay is longer.
The disadvantage is cost. The fiber is expensive and does not seem to get cheaper with time. There is a lot of preparation needed to terminate the ends of the fiber which requires skill.

Regular wires just transmit data digitally. While this works quickly, optical works much faster. Optical fibers, transmit the digital signal into light at the start of the cable, then decode it back into digital signals at the receiving end. This means that for most of its travel time, data is traveling at the speed of light.
