Simple optic communication systems such as blinker lights for ship-to-ship and ship-to-shore links, automobile turn signals, and traffic lights have low information capacities and their range of working is limited in distance. A major breakthrough leading to high capacity optic communications was achieved with the invention of LASER in 1960. In 1966, Charles K. Kao fabricated a glass fiber which could transmit light for short distance only. Kao suggested that it would be possible to transmit light signals over long distance using fibers made of purer glass and modulated infrared light. This course will provide the knowledge and understanding of the fundamental principles and concepts of Optical Fiber based transmission systems.
