    Thank you everyone for replying. I will post my questions about it in SYSTEM, I didn’t know it works like that.
    Dear Ahmad, that explains a lot of my doubts considering the interpretation of the response. When I do not use the circulator the signal looks like it was reflexed from the fiber, not distracted along its length. The intensity of the reflexed impulse changes with its length, but it still looks like one point reflex.
    Do you happen to have any idea how to interpret and analyze this signal?
    Furthermore, when I add the circulator th backsacttered signal completely dissapear, I am really confused why it happens.

    Thank you very much.

    Dear Ahmad,

    I simulated my otdr project in new optisystem, but unfortunately it is still not working as I cannot see the backscatered signal in the output of the circulator where the apd detector is. On the other hand I can see the backscattered signal on the optical time domain visualizer. Do you have any ideas what might cause that?

    Best regards,
