Detailed explanation-1: -Near end crosstalk (NEXT)NEXT is a measure of the ability of cabling to reject crosstalk. Interference between two pairs in a cable is measured at the same end of the cable as the interfering transmitter. Crosstalk is undesirable.
Detailed explanation-2: -Cross talk occurs in two ways. Near-end cross talk (NEXT) happens when a signal from a transmitter at one end of a cable interferes with a receiver at the same end of the cable. Far-end cross talk (FEXT) occurs when a signal interferes with a receiver at the opposite end of the cable from the transmitter.
Detailed explanation-3: -Crosstalk interference is an undesirable phenomenon in communication channels. It happens when the signals from one line pick up with a signal in the neighboring line, and it can greatly affect the privacy of communications.
Detailed explanation-4: -Crosstalk in cabling As it relates to structured cabling, crosstalk is electromagnetic interference from one unshielded twisted pair (UTP) to another. Typically, it occurs because they are running in close proximity to each other.
