Optical communication

Optical communication is any form of communication that uses light as the transmission medium.

3. Ancient Optical Communications Signals with Smoke and Fire : not very secure Mirror Reflection

4. Optical fibers Use total internal reflection to keep a light ray trapped within the denser glass of the center of a composite cylindrical glass fiber, the core .

5. It is as if light rays are guided down the core of the fiber in a zigzag path by a succession of total internal reflections at the boundary between the core glass and the less dense glass surrounding it, the cladding.

6. High data carrying capacity, High volumes of any kind of data, text, graphic, sound/voice and video carriage made possible, Excellent quality of output as compared to input with use of optical communication,

7. once installed successfully, subsequent only negligible maintenance required thereby reducing breakdown/shutdown periods and cycles. Carriage of data over large terrestrial distances became possible, Carriage of data without visible medium made possible and lot more.

8. The only disadvantage is high installation cost but since such installations are made over large distances and accrued revenue is very large, this high initial investment does not matter much.
