NeXT Near End Crosstalk (NEXT) is an
electromagnetic interference (EMI), also known as
crosstalk, introduced on
UTP by close by wires, usually running in parallel with the NEXT induced wire."Near End" refers to the inductance of EMI in the end closer to the end being measured on the alternate wire in a pair.In opposition to this,
FEXT (Far End Cross Talk) is the detection of EMI on a wire whose inductance is at the far end from the measurement point. FEXT is weaker at the other end due to attenuation of the crosstalk signal.

Crosstalk that is propagated in a disturbed
channel in the direction opposite to the direction of
propagation of a
signal in the disturbing channel. Note: The terminals of the disturbed channel, at which the near-end crosstalk is present, and the energized
terminal of the disturbing channel, are usually near each other. (
