Marines with 7th Communication Battalion, III Marine Expeditionary Force Information Group conducted field testing of a new Free Space Optics system at Camp Hansen, Okinawa, Japan, Aug. 21.
FSO is an optical communication system that transfers data on a highly secured and nearly undetectable infrared laser, separate from the radio frequency spectrum. The FSO allows for higher data rates compared to the current systems in the Marine Corps. This allows more users on a single network, and larger files, imagery and information to be transmitted.
