10.7. Measuring the distance to
fault
10.7.1.
DTF
–
distance
to
fault
– distance to damage. This plot (Figure 10.12) ) allows you to meas-
ure the distance to fault or heterogeneity of the cable in the communication lines. Calculated as the in-
verse Fourier transform of the frequency array of reflection coefficients.
