Calculation Method for Total Loss
• Cumul-Loss (Cumulate Loss)
The integrated value of the splice losses at each event from the measurement reference point (S)
is displayed. This is the conventional calculation method (firmware version 1.02 and earlier).
Splice loss of each event
• Loss between S and E
The loss (TPA approximation method) between the measurement reference point (S) and the
end of fiber (E) is displayed.

Note
If Loss between S and E is selected, markers

are placed automatically at the measurement
reference point (S) and the END point (E) when event analysis is executed.
Calculation Method for Total Return Loss
Select whether to include the return loss value at the end of fiber (E) in the total return loss.
Include END: The value is included in the total return loss.
Exclude END: The value is not included in the total return loss.
