6.2 NEXT
NEXT (Near-End Crosstalk) is a measure of noise coupled between two
twisted pairs measured at the same end of the cable as the disturbing signal
source. When you test a twisted-pair cable, NEXT is measured using all pair
combinations.
NEXT is one of the tests run during Autotest and Quick Check. It is one of
the fundamental certification tests for Category 3, 4, and 5 UTP cabling. It
can also be run individually as an Extended Functions test.
NEXT tests for excessive crosstalk between pairs and proper pair connections.
