In the job.
THANK YOU FOR YOUR ATTENTION :) FIBBER-OPTICAL COMMUNICATION In fiber-optic communication, information is transmitted by sending light through optical fibers.
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. First developed in the 1970s, fiber-optic communication systems have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age. Because of its advantages over electrical transmission, optical fibers have largely replaced copper wire communications in core networks in the developed world.
The process of communicating using fiber-optics involves the following basic steps: Creating the optical signal involving the use of a transmitter, relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak, receiving the optical signal, and converting it into an electrical signal.
