A new optoelectronic oscillator with switchable frequency and high performance, based on multiple long fiber loops, is demonstrated. This oscillator can simultaneously obtain low phase noise and high side mode suppression ratio, and provide different output frequencies by selecting narrow bandpass filters. In the experiment, the optoelectronic oscillator can operate at 8, 9, 10, 12 GHz by switching the filter frequency. For each frequency, the output power higher than 10 dBm and side mode suppression ratio more than 60 dBc can be realized. The phase noise lower than -130 dBc/Hz at 10 kHz offset can be obtained. The experimental results agree with the theoretical analysis, which proves the correctness of the method.
