Abstract

We propose and experimentally demonstrate a 5 × 100-Gb/s DFT-spread OFDM-WDM-PON employing probabilistic shaping (PS) 16QAM modulation format with direct detection. Each optical carrier at the optical line terminal (OLT) is a 25-Gbaud PS-16QAM OFDM according to the near-Gaussian distribution. The spectral efficiency of the OFDM-WDM-PON can be improved under the same average power and received power sensitivity by PS. The experimental investigation shows that the joint equalization of DFT-spread and PS signal can further increase the tolerance to fiber nonlinear effects in OFDM-WDM-PON.
