Radio over fiber systems in a microwave/millimeter wave band experience a severe signal fading due to fiber dispersion. However, parametric amplification in transmission fibers, known as modulation instability, can compensate for the signal fading. In this paper, we experimentally demonstrate radio over fiber transmission of 111.689 Mbps BPSK signal with a carrier frequency of 10.804GHz, and measure bit error rates varying the optical transmission power. For the fiber launched power of 0dBm, we observe a power penalty of 5.8dB in the transmission over a 25km fiber, though by increasing the fiber launched power up to +10dBm, we successfully reduce the power penalty by 1.1dB.
