In this paper, we demonstrate <strong>and</strong> analytically analyze a digitized RF-over-fiber transport<br />

scheme for uplink transmission in a Radio-over-Fiber system. We achieve significant<br />

improvement in both signal-to-noise ratio (SNR) <strong>and</strong> dynamic range. The experimental <strong>and</strong><br />

analytical results show that digitized RF link is less susceptible to nonlinearity <strong>and</strong> fiber<br />

attenuation which makes this scheme well suited for long-reach optical backhaul for wireless<br />

networks.<br />
