  "term": "ACR",
  "field": "Industrial and trades",
  "definition": "A performance metric in telecommunications that compares the attenuation of a signal to the level of far-end crosstalk (FEXT) from other pairs in the same cable. The Attenuation to Crosstalk Ratio (ACR) indicates the signal-to-noise margin, with a higher value signifying better performance and more available bandwidth. For a cabling link to pass certification testing, such as for Category 6, the ACR value must remain positive across the entire tested frequency range.",
