Abstract
Orthogonal frequency division multiplexing (OFDM) is an extensive technology in commercial communication because of its
ability to mitigate channel distortions. OFDM technique achieves high spectral efficiency and requires simple channel
equalization. It has received significant interest to photonics community as an attractive solution for long-reach
transmission, as it offers a reduced signal bandwidth and enables simple digital equalization. This paper investigates the
performance of optical OFDM (OOFDM) system using fiber nonlinear effects. A new approach named impairment factor is
introduced to reduce the fiber nonlinear impairments of the system. The simulation results have been provided for dual
polarization OOFDM system with multi-level quadrature amplitude modulation (M-QAM) applied to the optical signal
subcarriers. The performance of the proposed OOFDM system is compared to the conventional single carrier optical
system with M-QAM for the same number of information bits.
