What is Near-End Crosstalk?

Near-end crosstalk loss is a key performance parameter for cabling links. It refers to the signal coupling scale from twisted pair to twisted pair. The measurement of this parameter is to test the signals leaked from other wire pairs, and the test of this item is to measure at the signal transmitting end (near end). Substandard near-end crosstalk loss will cause the network connection to fail completely. ^[1]
