high capacity and low cost optical short and medium reach Direct Detection (DD) system becomes an inevitable trend. This paper first comprehensively reviews the advanced spectral efficient modulation formats in flexible transceiver and modulation methods which include the Double Side Band (DSB) and Single Side Band (SSB) methods to different transmission scenarios. In addition

considering the issue of different physical layer impairments

the details of the equalization schemes are reviewed. Finally
