attenuation crosstalk ratio Last modified: Monday, September 20, 2004  Also known as headroom, attenuation crosstalk ratio (ACR) is the difference between attenuation and crosstalk at a given frequency along a cable. Measured in decibels, ACR is a calculation used in networking transmission to assure that a signal transmitted across a twisted-pair cable is stronger at the receiving end than any interference signals imposed on that same pair by crosstalk from adjacent pairs.   Related Categories Fiber Optics Networks Telecommunications Related Terms 10Base-T attenuation CDDI coaxial cable crosstalk fiber optics local-area network optoelectronics ribbon cable attenuation crosstalk ratio Products : Top Store Offers: FLOTECHNIC Design  149.99Kicktronic is a compact, portable electronic bass drum with a true analog sound engine.
