Concatenated Multi-Level Coded Four-Dimensional Modulation for Short-Reach Coherent Optical Transmission
A 4D modulated 128-SP-QAM scheme employing concatenated MLC is proposed to mitigate PDL in short-reach coherent transmission system, achieving a 0.93 dB OSNR gain after 20 km SSMF compared with conventional PM-16QAM.
