What is the purpose of crosstalk testing in copper cabling?

Crosstalk testing is about how much signal from one pair leaks into the other pairs in a copper cable. The purpose is to verify that this interference stays within the limits defined for the cable category so the channel can reliably carry its intended data rate over the specified distance. When crosstalk stays within those category limits, the signal integrity is maintained and the link can meet its performance expectations. This focus distinguishes crosstalk testing from tests that check insulation resistance, shield grounding, or delay skew, which address different aspects of the cabling system.
