A theoretical study of the transmission performance of the optical orthogonal frequency division multiplexing (OFDM) system was conducted as a function of number of subcarriers. It revealed that small number of subcarriers could improve the transmission performance because the optimum repeater output power of the system was increased. The reason of the improvement could be attributed to the nonlinear impairment reduction through the peak to average power ratio (PAPR) reduction.
