<P>PROBLEM TO BE SOLVED: To provide an RF optical transmission system that can easily modify the system configuration. <P>SOLUTION: Master-station radio equipment 10 includes a frequency converting part 111 for converting radio-frequency signals of a plurality of systems to a plurality of intermediate-frequency (IF) signals of different frequencies, a signal combining/distributing part 112 for electrically combining the plurality of intermediate-frequency signals for distribution to the slave-station equipment, and a plurality of electrical/optical converting portions 113-1 to 113-n for converting the IF signals to the combined optical signals in order to output to the slave-station equipment 13-1 to 13-n via the optical fibers 121-1 to 121-n. Each level stabilizing device 16-11 to 16-n2 respectively includes a signal combining part 161 for distributing the IF signals sent from the slave-station equipment, a frequency converting part 162 for converting the distributed IF signals to radio signals in the predetermined radio-frequencies of the plurality of systems, amplifiers 163, 165 for amplifying the radio signals, and a plurality of antenna devices 169-0 and 169-1. <P>COPYRIGHT: (C)2011,JPO&INPIT |
