This paper presents a modification in conventional asymmetrically clipped optical OFDM (ACO-OFDM) frame for direct detection intensity modulation (DD-IM) system. Proposed dual frame OFDM consists of two similar frames and transmitted with optical phase conjugation for dispersion and non-linearity mitigation in optical fiber. Proposed system is compared with another scheme- phase conjugated sub-carrier coding (PCSC) in OFDM. Authors have compared the proposed system performance with PCSC for single mode fiber (SMF) with length 10 km and multi-mode fiber (MMF) with length 100 meters. Simulation results show that PCSC scheme performs better for SMF but in case of MMF, performance of proposed system is better.
