Improved Physics-based Raman Amplifier Model in C+L Networks through Input Parameter Refinement
Yihao Zhang, Xiaomin Liu, Qizhi Qiu +4
We propose a n input parameter refinement scheme for the physics-based Raman amplifier model. Experiments over C+L band are conducted. Results show the scheme can lower the physica…
