摘要
本文通过计算机系统仿真研究了以相敏光放大器(PSA)作为中继光放大器的非零色散位移光纤通信系统的传输性能 ,分析了PSA系统的码间干扰(ISI)限制距离与信号速率、光纤色散、放大器间距和放大器平均输出信号功率的关系 。
The transmission performance of non_zero dispersion shift fiber optical communication system using phase_sensitive amplifier (PSA) as an in_line amplifier is theoretically analyzed by computer simulation. We've simulated and analyzed the relations of ISI limit distance of PSA system with signal rate, optical fiber dispersion, amplifier spacing and average signal output power, along with the effect of phase_shifting between pumping and signal light and the signal pulse waveform to the transmission performance of in_line PSA system.
