Bridge tap detected at about 86 m.
The distance to a bridge tap is approximate (
≈
) because
multiple reflections from the bridge tap interfere with
length measurements.
Note
Bridge tap detection requires a minimum of two
branches (excluding the branch connected to the
tester) at least 15 ft (4.6 m) long each, with a
combined length of at least 40 ft (12.2 m).
Delay skew failure (1000BASE-T only). Delay skew results are
available only if delay skew failed.
Delay skew is the difference in the arrival times of signals on
the cable pairs. See the Appendix for causes of delay skew
problems.
Note
If both the length test and skew test failed, only
the length results are shown.
