iOLM Results
The iOLM acquisition results are displayed in the iOLM table for all the
wavelengths at which the iOLM acquisition was performed.
Note: The iOLM results are not displayed if they are not available.
When a multiple-wavelength acquisition is in progress, only the
wavelength currently being acquired and the ones already completed are
displayed. Link loss, link ORL, and propagation delay (multimode only) are
displayed for each wavelength. For the link loss and the link ORL, the
values are tested and displayed according to current pass/fail settings.
Note: The propagation delay (multimode only) is a global link measurement
which is measured by the OTDR. It is defined by the amount of time
necessary for a signal to travel from point A to point B. It may vary between
wavelengths.
Note: If the link ORL value is saturated, that is, if the value is displayed with a
< symbol, the value will be tested for Pass/Fail and it will be able to specify
the fail status if the value is fail, but it will not be able to specify the pass
status.
