ABSTRACT:
The present invention relates to a frequency division multiplex system for transmitting a plurality of radio frequency signals of differing frequencies from a transmission station to a receiving station. The system is comprised of a plurality of modulated light sources in the transmission station, each providing a light signal. A major optical fiber unit joins the transmission station with the receiving station for transmitting a mixed light signal comprised of the light signals from each light source. A plurality of minor optical fiber units are provided, each connecting one of the light sources to the major optical fiber. A photodetector is located in the receiver station. The detector is operatively associated with the major optical fiber for detecting the radio frequency signals from the mixed light signal.
