hi Mohamed
thanks a lot for your help but I can’t see the backscattered Brillouin signal yet. In the attached file, I expect that optical time domain visualizer_3 shows a signal but shows nothing. However, the optical spectrum analyzer_3 shows the Backscattered Brillouin signal in frequency domain. how can I solve this problem?
is it optisystem proper for analyzing distributed fiber optical sensors in time domain?
or
does optisystem have the capability of simulating OTDR(optical time domain reflectometry) systems in time domain?
