Fig. 1. Transmission model used for investigating the impact of transceiver noise on DBP systems, where the transceiver noise is divided equally in transmitter and receiver
Fig. 2. Received SNR versus optical signal power per channel after 20×90 km transmission for (a) PSCF link; (b) SSMF link; (c) NZDSF link
Fig. 3. Constellation maps after EDC and FF-DBP for Nyquist 9-channl WDM 256 Gbit/s PM-16QAM over SSMF link. (a) With EDC only; (b) with FF-DBP and no TRX noise included; (c) with FF-DBP and TRX noise, transceiver SNR of 20 dB
