MPORTANT
The analysis will stop as soon as the loss of an event crosses the
end-of-fiber (EoF) threshold. The application will mark the event as
an end-of-fiber event.
In this case, even if you selected the option, the application will not
search the “noisy” portion of the trace for reflective ends of fiber.
If you want to do so, you will have to increase the EoF threshold
(see Setting the Analysis Detection Thresholds on page 148).
