Thank you I will try to use it

Which OTDR component ?

[MohamedParticipant]

The purpose of my simulation on Optisystem that i get results similar to practical design that I made, Which is to measure the backscattered light returning from the fiber as value and the delay time to be able to get the OTDR analysis correctly and to calculate the best pulse width with best resolution to get a better analysis for the fiber, So what i am doing now is configuring how my design is going to work.

Dear Ahmed,
I am so thankful for your help, I managed to receive the backscattered signal but its not delayed as it appears on the visualizer on the same exact time of the input signal as it is supposed that I see a time delay in my simulation between the input and output signals but only amplitude of the signal is affected, So can you tell me why is that ??

[MohamedParticipant]

How do i create the right spatial information regarding the backscattered light ??

[MohamedParticipant]

Dear Ahmed,
Thank you for replying first, I already did so and tried to receive signal power at the output port of the coupler using Optical power meter connected to the PIN photodiode, But the optical power meter gives me received signal power = -100 dbm and only reads noise power and the photodiode don’t detect anything.
