      Is it possible to measure the delay time between input pulse and output pulse of the fiber ?? and if we use a bidirectional fiber can we observe a delay between back scattered and input power ?

      Dear Mohamed,
      You should be able to measure the delay between input and output pulses in the fiber. You may try dual-port scope in the electrical or optical domain depending on your application.
      There is also Photonics All-parameter Analyzer that can be used for such measurements.
      Backscattered signal is not a localized signal. It is only a time domain random signal representing the Rayleigh scattering. This signal can’t be used for OTDR application. However, OptiSystem has an OTDR component that allows users to design the system.
