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.
