8.10.2.1 Testing Cables with the LoopMapper
Figure 8.10.2.1A shows an example of a LoopMapper test result on a 1000-ft cable with an open cable end.
The large pulse near 0 distance is reflection from the CableSHARK coupling with the head of the cable, the
reflected pulse near 1000 ft is the reflection coming from the open end of the cable. The cursor is currently
located at this point, please note the Angle= 0
° confirming the open cable end. At the bottom is the graphical
representation of the cable topology indicating the total length for that segment and the open circuit
condition, which is automatically determined by the CableSHARK . The user can choose to move the cursor
from where the CableSHARK has placed it.
