Modifying iOLM Settings (FR2-FC Mode)

Note: If the link ORL value is saturated (displayed with a < symbol), the test is

still performed to obtain a pass/fail status. However, you can only
determine that the status is fail and the pass status cannot be specified.

5. In the Test Settings table, modify the IOR and the Backscatter values

as needed (single mode shown, but also possible for multimode
measurements).

Note: The values set for 1550 nm are automatically computed for other

wavelengths. You can only edit the IOR and backscatter values for the
1550 nm wavelength, even if other wavelengths are available in the
selected iOLM measurement.

Note: When the IOR value is changed, the position and length of the section will

be updated, and when the backscatter value is changed it triggers a
reanalysis of the whole link.
