Bridge tap
A bridged tap will appear as a downward or negative
reflection, because the impedance reduces at the
point of the tap, sometimes followed by an upward
reflection caused by the end of the tap.
Water ingress
This cable system has water ingress starting at 213.5ft
from the beginning of the cable. The waveform of the
wet section will usually appear irregular and noisy
Load coil
A telephone network load coil will cause an
upward, high impedance reflection similar to an
open circuit. TDRs are generally unable to “see”
past a load coil
