摘要
利用在频率范围内的噪声传输函数研究当色散主导和非线性主导时非线性相位噪声传输,并基于多信道多光纤段的WDM系统,利用LEM-SSFM数值方法计算非线性光纤系统的SNR,从传输距离,信号功率和放大器的数量三个角度研究非线性相位噪声的传输及其对系统性能的影响。
This paper first studies the propagation of nonlinear phase noise(NPN) through transfer function defined in under effect of dispersion and Kerr nonlinearity respectively in the frequency domain.Based on the theory and adopted local-error method Split-Step Fourier Method(LEM-SSFM),it analyzes NPN and the system performance by SNR from the transmission distance,launch power and number of amplifier under both dispersion and nonlinearity effects in a multi-channel multispan wavelength-division multiplexed(WDM) system.
