Signal Performance Results

Note
Signal performance results for cables
less than 13 ft (4 m) long may be
unreliable.
Qualified/unqualified result for the signal
A
performance. Signal performance includes
crosstalk, insertion loss, and return loss. For
1000BASE-T, ELFEXT (equal-level far-end
crosstalk) is also tested.

B Information about the signal performance:
•
Qualified for <application name>: The cabling will support the
application.
•
No Signal Performance tests needed for qualification: Appears
for the Telco and Wiremap only tests.
•
Wiring fault! Not tested.: The tester does not evaluate signal
avv23f.eps
performance if there is a wiremap, length, or delay skew fault.
•
Connection fault: A localized crosstalk fault was detected.
Localized faults are usually caused by bad connections. Check
the cabling at the location given. See the Appendix for other
causes of crosstalk faults.
•
Distributed cable faults: Crosstalk or an impedance problem was
detected along most or all of the cabling. The cabling is of poor
quality or is the wrong category for the selected application.
