      Hello Everyone,

      I would like to design an OTDR (Optical Time Domain Reflectometer) system for fault finding and localization purpose in TWDM-PON system.Here, i have to measure ReyLeigh back scatter signal.

      I have found some similar design in Optisystem forum, But could not give any output at PIN/APD. Does anyone knows how to Overcome it?

      Thanks
      Maddy

      Hello Maddy,
      OptiSystem will offer phi-OTDR component and interrogator in its coming 16.0 version early next year.
      Your design is missing delay element to allow backward calculation. Also, the measured backreflected Rayleigh signal is a parametric signal represents the average backreflected signal power.

      regards,
      Ahmad
