2. Cable tester - Wikipedia

   en.wikipedia.org/wiki/Cable_tester

   A cable tester is an electronic device used to verify the electrical connections in a signal cable or other wired assembly. Basic cable testers are continuity testers that verify the existence of a conductive path between ends of the cable, and verify the correct wiring of connectors on the cable. More advanced cable testers can measure the ...

3. Attenuation-to-crosstalk ratio - Wikipedia

   en.wikipedia.org/wiki/Attenuation-to-crosstalk_ratio

   Attenuation-to-crosstalk ratio (ACR) is a parameter that is measured when testing a communication link, which represents the overall performance of the cable. [1] AcR is a mathematical formula that calculates the ratio of attenuation to near-end crosstalk for each combination of cable pairs. [ 2 ]

4. Copper cable certification - Wikipedia

   en.wikipedia.org/wiki/Copper_cable_certification

   In copper twisted pair wire networks, copper cable certification is achieved through a thorough series of tests in accordance with Telecommunications Industry Association (TIA) or International Organization for Standardization (ISO) standards. These tests are done using a certification-testing tool, which provide pass or fail information

5. Crosstalk - Wikipedia

   en.wikipedia.org/wiki/Crosstalk

   Near-end crosstalk (NEXT) NEXT is a measure of the ability of a cable to reject crosstalk, so the higher the NEXT value, the greater the rejection of crosstalk at the local connection. It is referred to as near end because the interference between the two signals in the cable is measured at the same end of the cable as the interfering ...

6. Cable fault location - Wikipedia

   en.wikipedia.org/wiki/Cable_fault_location

   Murray loop test employs the principle of wheatstone bridge for locating the fault. To perform this test, it is necessary to have a sound cable running alongside the faulty cable. One end of the faulted cable is connected through a pair of resistors to the voltage source. Also a null detector is connected. The other end of the cable is shorted.

7. Continuity tester - Wikipedia

   en.wikipedia.org/wiki/Continuity_tester

   Entry-level cable testers are essentially continuity testers. A continuity tester is an item of electrical test equipment used to determine if an electrical path can be established between two points; [1] that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the apparatus. [1]
