Abstract

A coherent fiber-optic transmission systems of OFDM signals is considered. The channels are formed using spectral-efficient modulation formats (QPSK and M-QAM). The influence of nonlinear phase noise arising in an optical fiber on channel signals is studied. It is shown that nonlinear phase noise appearing in the optical path is converted into amplitude noise and, mixing with the noise of optical amplifiers, leads to a decrease in the signal quality factor. Estimation formulas for determining the noise immunity of channel signals by calculating the Q-factor are given.

相干光纤传输系统中非线性相位噪声对幅相信道 OFDM 信号的影响

摘要研究了 OFDM 信号的相干光纤传输系统。信道采用频谱效率高的调制格式（QPSK 和 M-QAM）。研究了光纤中产生的非线性相位噪声对信道信号的影响。研究表明，光路中出现的非线性相位噪声会转化为振幅噪声，并与光放大器的噪声混合，导致信号品质因数下降。文中给出了通过计算 Q 因子来确定信道信号抗噪声能力的估算公式。
