Since Free Space Optics (FSO) operates in an unlicensed frequency, and is a comparatively cheap, easy-to-deploy, and very-high-capacity broadband solution, enterprises around the globe have been using it as a means of connecting dispersed office LANs, and for redundant fiber backup. These applications are a crucial part of the market for FSO vendors, and have helped endorse the benefits of the technology; however, there are a multitude of other applications within the service provider segment, such as metro ring extension and Gigabit Ethernet backhaul, that will generate major revenue for the FSO players. But the deployment of FSO in carrier networks must be carefully assessed, as the technology has some inherent limitations: FSO is a line-of-sight (LOS) technology The reliability of an FSO link is affected by fog, scintillation, and building sway. Links must be constructed at distances ranging from 820.25 feet (250 meters) to 6,562 feet (2 km) in order to decrease susceptibility to interference.
