Abstract
Recently, radio-on-free-space optical (RoFSO) technology is regarded as a new universal platform for enabling seamless convergence of fiber and FSO communication networks, thus extending broadband connectivity to underserved areas. In this article, an experimental demonstration of the newly developed advanced RoFSO system capable of transmitting the Japanese integrated services digital broadcasting- terrestrial (ISDB-T) signals over a 1 km FSO link is presented. Our innovative system combines a new generation full optical FSO system with radio over fiber technology. Important performance quality metrics like the modulation error ratio and bit error rate are measured and analyzed to characterize the deployment environment influencing the transmission of ISDB-T signals over the FSO link. The obtained results can be used for designing, predicting, and evaluating the RoFSO system capable of transmitting multiple wireless services over turbulent FSO links.
