Managing Element
When an element or a section is selected from the Link View, the details of
the corresponding element or section are displayed in Element/Section
Details tab. The loss, reflectance, wavelength, and corresponding pass/fail
status for loss and reflectance will be displayed.
Note: It is possible to underestimate the loss or reflectance value if the noise level
is too high (for instance, after a lot of loss on the link, the noise levels
increase). In that case, it is possible for the signal processing algorithms to
detect an element, and to estimate the loss/reflectance values, but since the
measured signal does not completely clear the noise floor, the loss or
reflectance values are likely to be underestimated. If the loss or reflectance
value is underestimated, the value is displayed with a > symbol.
