About the Course

Satellite communication and optical communication are two different technologies used for transmitting information over long distances, each with its own unique characteristics and applications. Satellite communication relies on artificial satellites orbiting the Earth to relay signals, while optical communication uses light, typically through fiber optic cables or free-space laser links, to transmit data. Satellites act as relay stations in the sky, receiving signals from one location on Earth and transmitting them to another. This enables communication across vast distances and over areas where terrestrial infrastructure is limited. Optical communication transmits data using light signals, either through fiber optic cables or free-space laser links. Fiber optic cables confine light to a narrow path, while free-space optical (FSO) communication uses lasers to transmit data through the air.
