Phase conjugate technique can compensate second-order dispersion and nonlinear effect simultaneously and efficiently. It is one of the most promising dispersion compensation techniques that has nothing to do with signal bit rate and modulation method. The propagation characteristics of the ultrashort Gaussian pulse signal in the mid-range phase conjugate communication system are theoretically analyzed under high-order dispersion. The numerical simulation of the propagation characteristics of the femtosecond Gaussian pulse signal under the second-, third-, and fourth- Dynamic Transmission in Fiber Dispersion Management Chain Based on Mid-Range Phase Conjugation Technology. The results show that the combination of phase conjugation and high-order dispersion management can not only compensate and recover the signal distortion and distortion introduced by all dispersion and nonlinearity including odd-order and even-order dispersion, but also reduce the time-division multiplexing The interaction between the pulses causes the signal to resume waveforms after one cycle of transmission, thereby improving the compensation performance of the phase conjugate system for distorted signals
