本文详细介绍了四进制 PWM 光纤通信系统相位抖动的分析方法。在本文中,通过建立时钟提取网络的低通滤波器数学模型,从而导出了相位抖动的统计特性以及时钟提取网络参数和波形参数对相位抖动均值和方差的影响。
This article describes in detail the analysis method of phase jitter in the quaternary PWM optical fiber communication system. In this paper, the statistical characteristics of phase jitter and the influence of clock parameters and waveform parameters on the jitter mean and variance of phase jitter are derived by setting up a mathematical model of low-pass filter for clock extraction network.
