摘要

•Mixed QAM modulation format helps to communicate signal over 80-km SMF distance.•A Comparative study between PAM4 and mixed QAM format is demonstrated.•Competent BER value (10−3) is achieved for Mixed QAM signal.•Proper EVM< 10.3%, <13% (32 QAM and16 QAM)) are obtain.•High SNR value, acceptable and clear constellation and eye diagrams are achieved.
