Establishing Thresholds
Establishing Thresholds
You can establish two types of thresholds: the dispersion and slope 0
thresholds.
The Dispersion Threshold will be displayed when the fiber you test
surpasses the dispersion level you allowed. It is applied to every
wavelength and will be displayed in the Results Table tab, where you will
have three possible results:
³
if your acquisition did not exceed the specified threshold.
³
if your acquisition exceeded the specified threshold.
³
--- if there are not enough points to calculate the fit or for the dispersion
per kilometer if the fiber length is unknown.
Note: Symbols are only displayed if you have selected a threshold.
