摘要：

Attracting increasing attention in recent years, the Free Space Optics(FSO) technology has been recognized as a cost-effective wireless access technology for multi-Gigabit rate wireless networks. Radio on Free Space Optics(Ro FSO) provides a new approach to support various bandwidth-intensive wireless services in an optical wireless link. In an Ro FSO system using wavelength-division multiplexing(WDM), it is possible to concurrently transmit multiple data streams consisting of various wireless services at very high rate. In this paper, we investigate the problem of optical power allocation under power budget and eye safety constraints for adaptive WDM transmission in Ro FSO networks. We develop power allocation schemes for adaptive WDM transmissions to combat the effect of weather turbulence on Ro FSO links.Simulation results show that WDM Ro FSO can support high data rates even over long distance or under bad weather conditions with an adequate system design.
