Performance Analysis of an NG-PON Using IM-DD and Complex Modulation and Coherent Detection

This paper presents a Passive Optical Network (PON) performance analysis using modulation schemes based on amplitude and complex modulation. This research uses the simulation software OptiSystem in co-simulation with Matlab. Data transmitted at 50 and 100 Gbps employ four-level Pulse Amplitude Modulation (PAM-4) and 4-level Phase Shift Keying (Q-PSK) schemes. The results are presented in graphs corresponding to the relationship of Bit Error Rate (BER) and reception power for scenarios of different lengths and attenuation values, supported by constellation diagrams and eye diagrams, which show the performance of the Next Generation Passive Optical Networks(NG-PON).
