Manufacturing of optical fiber

Optical fibers as waveguides are widely used in communication and medicine. Optical fibers are used in different types of sensors. An optical fiber is consists of a cylindrical core made of a material of refractive index n. This cylindrical core is surrounded by a cladding made of a material of refractive index n’. This core-cladding system is surrounded by a plastic jacket.  Based on the material used foir the construction, there are three types of fibers. They are glass fiber, plastic fiber and PCS fiber. Glass fibers use glass material for the construction of both core and cladding. Plastic fiber use plastic material for the construction of both core and cladding.  PCS fiber use plastic material for the construction of cladding and glass material for the construction of core.  Some of the methods used for the construction of optical fiber are double-crucible method, inside vapour deposition method, outside vapour deposition method, chemical vapour deposition method, modified chemical vapour deposition method, plasma enhanced modified chemical vapour deposition method, plasma activated chemical vapour deposition method, plasma outside deposition method and vapour phase axial deposition method.
