                                                      What is Fiber Optic Cable

 

 

What is Fiber Optic Cable ?
In twisted-pair cable and coaxial cable, data is transmitted in the
form of electric frequencies. So copper wire has to be protected
from water and electromagnetic waves. In fiber optic cable, these
types of problems are not occurred.
The fiber-optic cable uses light to transmit data. A fiber-optic cable
consists of hundreds of thin glass fibers or strands of glass.
Each strand is referred to as optical fiber. Each optical fiber is as a
human hair. The glass is an insulating material, it is because these
are not affected by electromagnetic waves. Thus, they have much
lower data transmission errors.
The data transmission speed is very high because fiber-optic cable uses
light to transmit data. The data transmission speed is up to billions bits
per second.
The disadvantages of fiber optic cable are:
It is more costly and difficult to troubleshoot.
It is difficult to install and modify.
Therefore the fiber-optic cable is becoming more popular and replacing all
old cable system. Today telephone, banks, and television companies are
replacing their existing telephone and coaxial cables with fiber-optic cables.
