Free-Space Optics

Free-Space Optics (FSO) is a wireless communication technology that transmits data using light beams, usually laser or LED, through the open air. It works much like fiber optic cables but without physical cables, sending information directly through the atmosphere. FSO is used for high-speed internet, secure communications, or connecting remote locations where laying physical cables is difficult. It relies on line-of-sight and can be affected by weather conditions like fog or rain. Overall, FSO offers a fast, flexible, and secure way to transmit data over short to medium distances without physical infrastructure.
