Intoduction:
Fiber-optic communication is a method of transmitting information from one
place to another by sending pulses of light 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.
Today,optical fibers are not only used in telecommunication links but also used in the
Internet and local area networks (LAN) to achieve high signaling rates.
