从理论上分析了等线性损耗、等信道间隔与不等输入功率条件下DWDM通信系统在传输过程中,利用波长变换技术消除拉曼串扰的原理,得到了传输距离末端输出功率的规律性,并通过仿真进行了验证。这对于进一步研究消除光纤传输过程中的非线性效应,提高通信质量有着重要意义。
The principle of eliminating the Raman crosstalk by using the wavelength conversion technology during the transmission of DWDM communication systems with equal linear loss, equal channel spacing and unequal input power is theoretically analyzed, and the regularity of the output power at the end of the transmission distance is obtained. Verified by simulation. This is of great significance for further research to eliminate nonlinear effects in optical fiber transmission and improve communication quality.
