Distributed Nonlinear Phase Noise Compensation for Coherent Optical OFDM through Post Signal Processing

Yiran Ma and Junjie Li Network Technology Department;China Telecom Beijing Research Institute;Beijing;China

  We demonstrate a distributed nonlinearity compensation technique for 10.7 Gb/s coherent optical OFDM signals after 1000 km transmission.Over 2dB Q improvement has been observed after two-step compensation.……
