Did You know?

Optical fibers are composed primarily of silicon dioxide (SiO 2), though minute amounts of other chemicals are often added. Highly purified silica powder was used in the now-outmoded crucible manufacturing method, while liquid silicon tetrachloride (SiCl 4) in a gaseous stream of pure oxygen (02) is the principal source of silicon for the vapor deposition method currently in widespread use. Other chemical compounds such as germanium tetrachloride (GeCl 4) and phosphorus oxychloride (POC1 3) can be used to produce core fibers and outer shells, or claddings, with function-specific optical properties. The first step in manufacturing glass optical fibers is to make a solid glass rod, known as a preform. There are several methods to create a fiber optic cable like Modified chemical vapour deposition, outside vapour deposition etc.
