Data displayed in the event list include: serial number, category, position, plug-in loss,
attenuation coefficient, echo loss, and accumulate loss. “Serial number” indicates the
information of the nth event that currently displayed on the trace graph; “Category” indicates
the event category of the event point; “Position” indicates the distance from the initial point of
the optical fiber to the event point; “Plug-in loss” indicates the quantity of plug-in loss of the
event; “Attenuation coefficient” indicates the attenuation characteristics of the optical fiber
from the last event point to the current event point; “Echo loss” reflect the reflection value of
the event point; “Accumulate loss” indicates the loss value of optical fiber from the initial point
to the current event point. Contents of information of event list are shown in Fig.7-7. The event
point data and event section data are separately displayed in the event list. Serial number of
event only numbers the event points. Event category displays the following information by
picture: initial event, optical fiber section, reflection event, non-reflection event, and end event.
Corresponding pictures of event category are shown in Fig.7-8. When looking over information
of event list, click the icon “event” through the touch screen, then the information of event list
can be found in the info window.
