The fiber optic cable is one of the most important inventions of modern day. This allows for information to be transferred long distances in a short period of time. With out fiber optic cables the internet and television companies would not be what they are today. Their applications can range from telecommunications, aircraft, spacecraft, and medical technology.
The fiber optic cable is made of thin strands of glass fiber. This glass is coated to allow light to move through it. The term for this is known as cladding. What happens is the total refection of light will be increased by using a material with a low reflexive index. The cladding layer will stop light from being lost. While this occurs light will travel to the glass core. The glass fibers have the ability to transmit messages and images through beams of light. This means information can be transported at long distances. At the receiving section of the fiber optic cable the light beams are converted back into electrical current. The signal can then be decoded.
