The first optical wireless system installed in a major U.S. service provider network - and now deployed in 60 countries - the FlightSpectrum is the perfect balance of carrier-proven performance and surprising affordability. At the heart of the FlightSpectrum is a four-beam, four-receiver design that enables connectivity at distances of 5 kilometers (3.1 miles) or more. Deployed more than any other optical wireless product, the FlightSpectrum is the original benchmark that led the way for global mainstream adoption of free-space optics technology.
