“…Nevertheless, it was not designed to have a strong nonlinearity tolerance when applied in optical fiber transmission systems. In response the root optimized pulse (ROP) [11], root M-shaped pulse (RMP) [12] and root Polynominal pulse [13] were proposed to enhance the nonlinearity tolerance. Nonetheless, the experimental verifications for these pulses were all done at a roll-off factor of 1, which is not suitable for spectrally efficient transmissions.…”

We experimentally demonstrate improved intra-channel nonlinearity tolerance of the root M-shaped pulse (RMP) with respect to the root raised cosine (RRC) pulse in spectrally efficient 128 Gbit/s PDM-16QAM coherent transmission systems. In addition we evaluate the impact of dispersion map and fiber dispersion parameter on the intra-channel nonlinearity tolerance of the RRC pulse and the RMP via both simulation and experimentation. The RMP is shown to have a better nonlinear tolerance than the RRC pulse for most investigated scenarios except for links with zero residual dispersion percentage per span or the zero dispersion region of a fiber. Therefore, the RMP is suitable for extending the maximum reach of spectrally efficient coherent transmission systems in legacy links in addition to currently intensively studied standard single mode fiber (SSMF) based dispersion unmanaged links.

“…By using the root-raised cosine (RRC) pulse, the spectral efficiency of optical coherent single carrier systems can be improved compared to systems using the NRZ pulse [8]. The pulse shape optimized to reduce the effect of fiber nonlinearities is the Nyqusit pulses specifically designed for coherent optical communications compared to RZ, NRZ and RRC pulses [9].…”

The mid-nonlinearity temporal inversion (MNTI) technology based on optical phase conjugate (OPC) is firstly proposed to compensate the chromatic dispersion and nonlinearity effect of the fiber link in coherent optical orthogonal frequency division multiplexing (CO-OFDM) system. System performance is analyzed under different transmission distance and different dispersion coefficient of fiber link. Simulation results show that, compared with mid-span spectral inversion (MSSI) method, at least 2-dB Q-factor improvement is achieved for the CO-OFDM system.

“…For PM QPSK, two-level drive signals are required for the IQ optical modulator, while for PM 16-QAM, four-level drive signals are required. The four-level drive signals can be generated using either the RF combining of two two-level signals 2 or a high-speed digital signal processor and digital-to-analog converters (DACs) [3][4][5][6][7][8][9][10][11] .…”
