Abstract

This work investigates the effect of phase fluctuation averaging on phase fluctuation induced by intrachannel four-wave mixing (IFWM) in highly dispersed differential phase-shift keying transmission systems. Through repeatedly averaging the phase fluctuations of adjacent pulses, a simple analytical model and numerical simulation revealed that the IFWM-induced differential phase fluctuation is suppressed and convergent, even after an ultralong transmission. The influence of averaging the phase fluctuations on the bit error rate is also evaluated by the semianalytical method.

摘要

这项工作研究了相位波动平均对高度色散差分相移键控传输系统中由通道内四波混频（IFWM）引起的相位波动的影响。通过反复平均相邻脉冲的相位波动，一个简单的解析模型和数值模拟表明，即使在超长传输之后，IFWM引起的差分相位波动也受到抑制并收敛。还通过半解析方法评估了相位波动平均对误码率的影响。
