Light is the medium by which broadband and telecommunications signals are conceded over at the fastest speeds possible over these cables. It is bounded around the glass fibers, and produces total internal reflection to facilitate high speed light travel to carry data and other elements. The origins of this method came from a scientific demonstration by Daniel Colladon, a Swiss physicist, and Jacques Babinet, a French physicist back in 1842.
It demonstrated the behaviour of light as it approved through water flowing down a tube to form a downward fountain. By 1880, Alexander Graham Bell and Sumner Tainter used this method as a basis of the Photophone in the USA where voice transmits using light was carried out.
