A BERT Tester is used by cable installation teams to certify a cable is within industry standard specifications such as crosstalk.

A BERT tester measures the bit error rate of a data link by sending a known pattern and checking how many errors occur. This focuses on data integrity over the connection, not on the cable’s crosstalk characteristics. Crosstalk, which is interference between adjacent pairs, is a separate parameter that requires dedicated measurements such as NEXT and FEXT, typically done with a cable certifier or specific crosstalk test equipment. So, while a BERT test can tell you if a link delivers data reliably under test conditions, it doesn’t certify the cable’s crosstalk performance to industry standards. That’s why the statement is false.
