What is an Optical fiber? Mention five categories of it application?

Optical Fiber :

                             Optical fiber is a flexible, transparent fiber made of glass(Silica) or plastic, slightly thicker than a human hair.It can functions as a waveguide or light pipe to transmit light between the two and of the fibers

                              Fiber optical is an application. Optical fiber optical fibers are widely used in fiber-optic communications which permits transmission over longer-distances and higher bandwidths than other forms of communication.

Application of Optical Fiber : 

The application of optical fiber are given below :

i) SONET : 

                     It transfer multiple digital bit streams over optical fiber using lasers from light emiting diods(LEDs).

ii) Cable TV : 

                           Some cable TV comanies use a combination of Optical fibe and coaxial cable, thus creating a hybrid network.

iii) Backbone structure : 

                                            Optical fiber provides the backbone structure while coaxial cable provides the connection to the user premises.

iv) LAN : 

                Local are networks such as 100Base FX network Fast (Ethernet) and 1000base -X also use fiber-optic cable.

v) Long distance communication : 

                                                             Fiber-optic communication which permits transmission over longer distances and at higher bandwidths than other forms of communication
