    I will be working on a big fiber optics project and the entire series has been a lifesaver for me

      Glad I could help you understand the basics of OTDR. It's an essential tool for anyone working on fiber optic projects.

    Sir, Small correction in ur explation ..When Sharp pulse is there in OTDR trace means fiber termination not fiber break... When fibre break occurs then sudden drop of pulse will be displayed in OTDR trace...As I am BSNL JE, daily we use it in our field works.

  • @ayushsoni8983
    @ayushsoni8983 8 หลายเดือนก่อน

    sir in OTDR diplay section the y axis should be labelled as power because the power will keep on decreasing as we move farther from the source point.
    If you are mentioning attenuation on y axis the graph which is shown in video should rise because as we move father from the source we know that attenuation increases.
    I don't know why anyone hasn't mentioned it till know.

    How can we calculate refractive index using otdr? It was our previous university question.Kindly help me

    • @EngineeringFunda
      @EngineeringFunda  5 ปีที่แล้ว +4

      AT 9:40, see the Formula of distance,
      d = ct/2n
      So, if known length d of fiber is used, then by measuring time t, we can calculate core Refractive index.
