Optical Time Domain Reflectometer (OTDR)
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?
