We propose and experimentally demonstrate a frequency-separated model based digital pre-distortion (DPD) technique in intermediate frequency over fiber system. Frequency-separated model based DPD could mitigate distortion caused by optical and electrical components in the transmission system. To employ the proposed DPD technique, least-mean-square (LMS) algorithm is used to derive the coefficients of pre-distorting equalizer. By the proposed DPD, error vector magnitude was decreased and adjacent carrier leakage ratio was increased.
