Setting Pass/Fail Thresholds
Setting Pass/Fail Thresholds
You can activate and set Pass/Fail threshold parameters for your tests.
You can set thresholds for splice loss, connector loss, reflectance, fiber
section attenuation, span loss, span length, and span ORL. You can apply
the same pass/fail thresholds to all test wavelengths or apply them
separately to each one.
You can set different pass/fail thresholds for each available test
wavelength. These pass/fail thresholds will be applied to the analysis
results of all newly acquired traces with the corresponding wavelength.
By default, the application provides threshold values for the following
wavelengths: 1310 nm, 1383 nm, 1390 nm, 1410 nm, 1490 nm, 1550 nm,
1625 nm, and 1650 nm. However, if you work with files containing other
wavelengths, the application will automatically add these custom
wavelengths to the list of available wavelengths. You will then be able to
define thresholds for these new wavelengths. You can revert all thresholds
to their default values, except if they are associated with custom
wavelengths.
The loss, reflectance and attenuation thresholds that you set are applied to
all events where such values can be measured. Setting these thresholds
allows you either to ignore events with known lower values, or to ensure
that all events are detected—even the ones for which very small values are
measured.
