Performance investigation of polar coded IM/DD optical OFDM for short reach interconnection

In this paper, we design a novel polar coded intensity modulation direct detection (IM/DD) optical orthogonal frequency division multiplexing-based (OFDM) system used in short reach interconnection. The experimental results demonstrate the 9.5-dB net coding gain (NCG) at the BER of 1e-3 after 40-km standard single mode fiber (SSMF) transmission.
