We generated a 500-Gb/s AO-OFDM signal with DP-16QAM modulating each subcarrier and detected the signal using coherent detection. We investigated the effects of DSP oversampling and receiver bandwidth...
Low-Complexity Two-Stage Carrier Phase Estimation for 16-QAM Systems using QPSK Partitioning and Maximum Likelihood Detection
Low-Complexity Two-Stage Carrier Phase Estimation 16-QAM Systems QPSK Partitioning Maximum Likelihood Detection

OFDM is a promising candidate for LR-PON. We study the possibility of using OFDM for signal remodulation in the LR-PON. Three different colorless ONU architectures are tested and compared.
Experimental Demonstration of Optical 5-Gb/s 16-QAM OFDM Signal Generation and Wavelength Reuse for 1.25-Gbit/s Uplink Signal

5Gb/s 16QAM OFDM signal for ROF downstream link and 1.25Gb/s OOK signal via RSOA for upstream link are demonstrated. Negligible penalty is observed after 25km SMF.
Transmission of Five M-QAM Signals over a 4.4 km Silica Graded-index Multimode Fibre Link Using Subcarrier Multiplexing
Transmission Five M-QAM Signals Silica Graded-index Multimode Fibre Subcarrier Multiplexing
