摘　　要：本文在总结文献中己有工作的基础上,给出了光纤传输系统中普适的频域弱强度/相位调制的传输矩阵H,包含了光纤中各阶色散、非线性和光纤损耗的影响 指出奇数阶色散仅对矩阵分量的幅频特性产生影响,而偶数阶色散仅对矩阵分量的相频特性产生影响 困此,对弱强度/相位调制（噪声）而言,只有奇数阶色散才起作用.基于H矩阵,定量计算了分别用于强度探测系统、相位探测系统和光谱仪测量的强度噪声谱、相位噪声谱和光场噪声谱。A generalized frequency domain weak modulation transmission matrix H in optical fiber systems is presented in this paper. Simultaneous interaction of loss,nonlinearity and all order of dispersion in the fiber are taken into account.It is found that the odd-and even-order dispersion terms only change the amplitude-and phase-frequency response respectively, while the intensity and phase noise are only infected by the odd-order dispersion terms. Quantitative calculations of intensity, phase and optical field noise spectra are presented for intensity-detection,phase-detection and optical spectrum analyzer applications.
