Abstract

A fiber optics communication link (20) for a remote mobile (22) vehicle employs a single strand of optical fiber (26) to convey control data from a stationary control station (24) to the vehicle and to simultaneously convey environmental data generated by transducers carried by the vehicle back to the control station. At the control station, the received optical signals are converted to an electrical form and demodulated to recover the environmental data. Additionally, encoded and modulated optical signals corresponding to the control data are provided to the second combiner/splitter (56) for transmission via the fiber to the first combiner/splitter (36). At the vehicle the received optical signals are converted to electrical form, decoded and demodulated to recover the control data, and used to control the vehicle and transducers. Frequency multiplexing is used in different directions along the single fiber in order to eliminate noise due to reflections along the optical path.
