| 摘 要： | 从理论上分析了单信道光传输系统中SPM效应对传输性能的影响,并通过仿真得出了不同入纤功率情况下SPM效应对单信道光传输系统影响的定量数据,当入纤功率小于0 dBm时,SPM效应不明显;入纤功率在0～12 dBm时,SPM效应减弱了色散效应的作用,延长了系统的受限距离;入纤功率大于15 dBm时,SPM效应起主导作用,单信道光传输系统极限受限功率为18 dBm.

| Abstract: | SPM effect in single channel optical transmission system is analyzed qualitatively and quantitatively by NLSE and Chirp method. Qualitative data are achieved to study SPM effect in optical transmission system with different input optical power by simulation. SPM is unobvious when input optical power is less than 0 dBm, and when input optical power is greater than 0 dBm and less than 12 dBm, SPM weakens the GVD effect and extends the transmission distance. When input optical power is greater than 15 dBm, SPM is predominant in single channel optical transmission system and the maximum input optical power is 18 dBm. |
