ORL value

[aleko205]

Hi Guys,
In the .json dump file, ORL values are equal to zero.

 "KeyEvents": {
                "Summary": {
                        "ORL": 0.0,
                        "ORL finish": 0.0,
                        "ORL start": 0.0,
                        "loss end": 8.06012,
                        "loss start": 0.0,
                        "total loss": 2.976
                }

This happens in all files. however, in the Fiber trace viewer, it is shown well (https://prnt.sc/KsbfjGNekAYt ) What may be the reason? Is it possible somehow to get the ORL value from the sor file?

It must be something with your file because with tests files I have ORL are present in the final JSON.

the pyOTDR lib have been written by reverse-engieenring the binary sor format. Try to test with https://github.com/JamesHarrison/otdrs which is more accurate regarding the spec.
