Is Free-Space Optics a new technology?
FSO systems were first developed during the 1960s both domestically and internationally for secure communications by military. Recent advancements in the technology-and gnawing demand for bandwidth where fiber-optic cable is unavailable-have created a need for FSO in commercial telecommunications networks. FSO systems have been deployed for several years commercially in enterprise networks where a single end-user has a local area network linking two or more buildings. FSO links are deployed worldwide.
