Paper Abstract

Free-space optics (FSO) is a technology that uses modulated optical lasers to transmit information in a line-of-sight path through the atmosphere. To date, the major focus of FSO research and development has been toward the transmission of digital data, mostly for “last mile” applications. This paper investigates the simultaneous transportation of multiple analog radio frequency (RF) signals over a single FSO link using wavelength division multiplexing (WDM) technology. Experimental measurements of optical peak power and signal-to-noise ratio (SNR) indicate the suitability of FSO links for supporting WDM applications.
