local.description.resumoIn this paper, we investigate the performance of unrepeatered optical transmission using nonlinear compensation, and dynamic equalization enhanced by forward error correction (FEC) feedback. The digital back-propagation (DBP) algorithm is used for nonlinear compensation, while error correction is provided by spatially-coupled low-density parity-check (SC-LDPC) codes. The technique is experimentally evaluated by the unrepeatered WDM transmission of 16×400 Gb/s single-carrier channels (66 GBd DP-16QAM) within a 75 GHz grid over 403 km (64.7 dB span loss), achieving 2.58 Pb/s km. The results indicated Q2 margins to the FEC limit of up to 0.4 and 0.5 dB for 3 and 6-dBm average launch powers, respectively, exhibiting a tangible improvement compared with previous works.
