High speed optical communication is one of the research hotspot in optical communication field at present. A novel super-orthogonal modulation method based on quadrature amplitude modulation (QAM) and frequency shift key (FSK) is proposed for high speed optical orthogonal frequency division multiplexing (OFDM) system. The coding-modulation and demodulation-decoding scheme is designed. The principle and transmission performance of optical OFDM system with proposed super-orthogonal modulation method is simulated and analyzed. The research result will lay the foundation of optical communication realizing with high speed, large capacity and high efficiency transmission.
