Numerical Investigation of the Equalization Enhanced Phase Noise Penalty for M-Quadrature Amplitude Modulation Formats in Short-Haul Few-Mode Fiber Transmission Systems with Time-Domain Equalization

“…In this simulation, it is assumed that the group velocity of the LP 11 mode-group is lower compared to the LP 01 mode-group and hence the LP 11 mode-group arrives later [40]. However, there are FMF designs where the LP 11 mode may arrive earlier [41]. We consider both mode-selective DE/MUXes and non-mode-selective DE/MUXes in two separate models named model A and model B, respectively.…”
