The fiber optic is a medium for carrying information. It is a thread of glass through which a pulse of light travels at high velocity. This filament is flexible and is protected by plastic. The manufacturing of fiber optic is a delicate process and encompasses high technology.
The raw materials are large tubes of glass. First, they are submerged in a corrosive bath of hydrochloric acid. Then, the tubes are placed in a lathe and they are moved round. At the same time the tubes are heated with a hydrogen and oxygen flame. When the tubes become white, they are melted and stuck together. As a result, there is a larger tube.
The larger tube is placed in other lathe and it is moved round. Moreover, a mixture of gases is put inside the tube. Then, everything is heated. This mixture suffers a chemical reaction when it is heated and it becomes white powder. With additional heat, the white powder becomes what is known as nucleus of the fiber optic. The tube of glass that surrounds the nucleus is the jacket of the fiber optic.
The fiber optic obtained after this process is too thick to be used. The next step is making the tube thinner. The tube is placed in a tower vertically. One side of the tube is heated until the glass reaches the fusion point. The tube is stretched with the help of the extreme weight and gravitational forces. At the same time the tension tube is tested to obtain the desired tension.
Lastly, the fiber is passed through ultraviolet light to protect it from dust and other contaminants.
