Paper Abstract

Free-space optics (FSO) is a technology that uses modulated laser beams to implement point-to-point communications links without optical waveguides. In many cases, FSO technology can be deployed in metropolitan areas at costs lower than required to install new optical fiber infrastructure. To date, the primary concentration of FSO research and development has been toward the transmission of digital signals, particularly for "last mile" applications. This paper investigates the use of FSO technology for the simultaneous transport of multiple radio frequency (RF) signals over a single FSO channel. Experimental measurements of transmission response and dynamic range, over the frequency range 46-870 MHz, indicate the suitability of FSO links for cable television (CATV) applications.
