Fiber Structure
The diagram shows the typical structure of a fiber used for communication links. It has an inner glass core with an outer cladding. This is covered with a protective buffer and outer jacket. This design of fiber is light and has a very low loss , making it ideal for the transmission of information over long distances.
its is made of sleca (Glass)
Si+O2---------->SiO2
Core:
it is made of glass and it also called inner layer.the data travel on the core .the Reflective index of core 1.47.
Cladding:
it is made of selicon. it reflective index less then core 1.46.it is used reflect the signal on the core if the core is damage.
Outer More Jacket:
It is also called Epoxy .it is made of rubber.it is used to protect the core from breakage.
Light in a fiber
The light propagates along the fiber by the process of total internal reflection. The light is contained within the glass core and cladding by careful design of their refractive indices. The loss along the fiber is low and the signal is not subject to electromagnetic interference which plagues other methods of signal transmission, such as radio or copper wire links.
The signal is, however, degraded by other means particular to the fiber such as dispersion (described below) and non linear effects (caused by a high power density in the fiber core)
