Intrachannel Nonlinear Effects in Optical Time Division Multiplexing Dispersion-Managed Quasi-Linear Transmission System
The intrachannel cross-phase modulation (IXPM) and intrachannel four-wave mixing (IFWM) in dispersion managed quasi-linear systems is researched, and the role of the timing jitter induced by IXPM and the amplitude jitter and the ghost pulse induced by IFWM change with distance and dispersion map strength are analyzed theoretically. Then the theoretical analysis results are verified by the timing jitter, amplitude jitter and the generation of ghost pulse of a 25-1 pseudorandom binary sequence (PRBS) by using fast Fourier transform method. Finally, the stable transmission of 1600 km is verified in dispersion managed quasi-linear systems with dispersion map strength of 127 by numerical simulations. The results are important for high speed transmission based on single-mode fiber.
