Optical Fibre
What is Optical Fibre?
An optical fibre uses total internal reflection to carry a light beam over a long distance and around corners. I believe you remember condition for total internal reflection. The condition is light traveling from denser medium to a less dense medium & the incident angle greater than critical angle. A fibre is very thin. It is like a diameter of an hair strand, about 125 micrometer. Hundreds and thousands of them can be together. They are used since world war 2 time to transmit messages from one ship to another, separated by wide distance apart. The technology associated with the transformation of information as light pulses along a glass or plastic strand. The hundreds/thousands of these optical fibres are arranged in bundles in optical Cables. The bundles are protected by the cable's outer covering called the jacket.
