The method of transmission of the information from one place to the other by sending light through an optical fiber is called Fiber-optic communication. Here you will learn that the light that passes through the optical fiber forms an electromagnetic carrier wave that is employed to carry the information. This technology was developed in the 70s, when the fiber-optic communication systems were giving a revolutionary change to the telecommunications industry. The Fiber-optic communication has played a big role in the field of the Information and technology. Fiber-optic communication has many advantages over electrical transmission. Today one does not use the copper wires and the optical fiber has replaced copper wire communications when it comes to networking in the developed world today.
