The TP-P6 displays many attributes of a trace:
●
Type:
Different indicators are used for different event types. For detailed information pertaining to
specific types of events, please refer to the appropriate sections of this manual.
●
Number:
Event number (automatically designated by the OTDR application program).
●
Position:
Distance between the OTDR and the event.
●
Insertion Loss:
The loss caused by a loss event, measured in dB (automatically calculated).
●
Reflection Value:
Calculated value for each reflective event.
●
Attenuation:
The attenuation (loss) for each optical fiber length (loss/distance).
●
Accumulation:
The accumulated loss from the span starting point to the end of the span.
Note:
“Accumulation” is the calculation of all loss within the parameters and does not calculate the events
that occur outside of the designated parameters. To determine specific loss occurring within a specific
parameter, please refer to the loss results displayed in {Markers}.
11.14 Setting the Event Options
The event table lists all of the events within a particular trace. Events can be defined as any point where
a change in optical transmission was detected. Events cause loss, which can be caused by a lack of
transmission power or quality, faulty splices, defective or dirty connectors or crack/bends in the fiber. If
an event exists outside of the defined threshold, it will not be detected or displayed.
