History of Optical Fiber
It was the time of 1870 when the scientist John Tyndall was passing a ray of light through the water when he dropped a ray of light into the water falling from wicker. Then it was observed that the light ray also bends in the same direction where the water falls.
At that time, he had no idea that this small invention of his was going to change the whole world in the future. Over time, many experiments have been done on this subject. John Logie Baird and Clarence W. of America in 1920 when they were inventing modern TV. Then he got the idea to show the images using transparent rods. His idea changed the direction of the optical fiber itself.
Now scientists started thinking about it in a new way. In 1960, the term fiber optics was used for the first time by the Indian-origin scientist Dr Narendra Singh. In 1970 Corning Glass Works developed a bundle of optical fiber cables. Gradually, there was a lot of improvement in optical fiber.
After many experiments, the data transmission range increased from 5km to 10km and then to 50-100km. Today the scope of optical fiber has been established so much that it has covered the whole world.
Structure of Optical Fiber
The thickness of optical fiber cable is almost equal to the thickness of our hair. Now you will be surprised to know that despite being so thin, they transfer about 100 GB/second of data.
It is only made of glass or plastic, due to which it is very weak, for its protection, we give it about 8 layers of security.
Its outermost layer is made of polymer which acts as water protection. Then the subsequent layer is made of steel which gives it strength. Now this process is repeated two to three times. Due to this it becomes highly protected. Now, these cables are laid in the sea with the help of machines.
Through these cables, the data of the whole world is transferred. Or it would not be wrong to say that the Internet of the whole world runs on these cables.
