Hello,
I do investigation on backscattering signal involving Raman effect for my project. At first I enable Rayleigh Scattering option in the bidirectional fiber and its working fine. However when I enable Raman Scattering option, the backscattering signal is gone. Only parameterized signal. I tried vary the fiber length and Rayleigh value, but still no backscattering signal. Here I attached the sample. Please help me. Tq
Regards,
