40×117.6 Gb/s PDM-16QAM OFDM transmission over 10,181 km with soft-decision LDPC coding and nonlinearity compensation

Transmission of 117.6Gb/s optical PDM-16QAM OFDM signals over 10,181km is demonstrated at 25-GHz channel spacing with 4.7 b/s/Hz spectral efficiency. All the errors have been corrected by using 25% overhead QC-LDPC after multi-band nonlinearity compensation.
