Abstract
Free Space Optical communication (FSO) is a wireless communication system that employs light propagation across free space to transport data between two sites without the usage of fibre optic cables. It uses either lasers or light emitting diodes (LEDs) for high speed data transmission with enormous bandwidth, which makes it a desirable solution for modern communication systems. The FSO provides many advantages such as minimal installation cost, excellent security, licence free spectrum and fast implementation. It has wide application in satellite communication, military networks, urban connection and disaster recovery systems.
However, FSO communication is susceptible to atmospheric circumstances such as fog, rain, dust and turbulence which can impair the quality of the signal and the reliability of transmission. Recent advances in adaptive optics, hybrid RF/FSO systems and enhanced modulation techniques have improved the performance and reliability of FSO networks. With the increasing demand for high-speed Internet and next-generation communication technologies, FSO is becoming a promising alternative and complementary technology to traditional wired and radio-frequency communication systems.
