    For finer movement, touch active cursor and drag it to the desired position. The finest movement can be accomplished with the left and right buttons. Loss Measurements 2 Point loss 2 Point loss measurements take into account the difference in vertical height between where the A and B cursors cross the fiber trace to determine loss. This information is located on the main OTDR screen in the A-B section of the trace information as shown in Fig. 7.2. This is a quick method of checking the loss between any two points on a fiber optic link. dB/km The dB/Km (dB/Kft or dB/Mi) loss method takes the 2 Point loss in dB and divides by the distance between the cursors in Km (Kilometers), Kf (Kilo feet) or Mi (Miles). For accurate dB/.. loss measurements, the two cursors must be on level back scatter points at least 100m apart (NA will show for distances that are too short).

    Examples of these settings are as follows: Splice: If a 1.00dB splice loss is acceptable, set the threshold to 1.00. If a splice loss of 1.00 is the fail point, set the threshold to 0.99 ORL: If a -50dB reflectance is acceptable, set the threshold to 50. If -50dB is the fail point, set the threshold to 50.5. Link: If a 20dB, link loss is acceptable, set the threshold to 20. If 20db link loss is the fail point, set the threshold to 19.5. FTE-7000A-DWDM OTDR User's Guide Rev D 1/2021...
