Positive ACR calculations mean that transmitted signal strength is stronger than that of near-end crosstalk.

Near-end crosstalk (NEXT) Cross-talk measured at the end from which the disturbing signal is transmitted.

ACR is a mathematical formula that calculates the ratio of attenuation to near-end crosstalk for each combination of cable pairs.

Near-End Crosstalk (NEXT)

Near-end crosstalk (NEXT) loss is a measure of signal coupling from one pair to another with a UTP cabling link, and is length independent.

ACR is expressed as a figure in decibels (dB), between the signal attenuation produced by a wire or cable transmission medium and the near-end crosstalk (NEXT).

Near-End Crosstalk (NEXT) is an error condition that describes the occurrence of a signal from one wire pair radiating to and interfering with the signal of another wire pair.
