We propose a spectral power shaping technique for use in intermediate frequency (IF) over fiber systems. The technique redistributes the power of nonlinear components by adjusting the spectral power of the signal. Experiments performed using 10 km distance transmission system show that the proposed technique effectively controls the power of the nonlinear components in a broadband system. The feasibility of the proposed technique was experimentally verified in terms of the error vector magnitude (EVM) and degree of channel linearity.
