To prevent crosstalk in a keystone RJ-45 jack what is the minimum length of wire that should be untwisted?

To prevent crosstalk in a keystone RJ-45 jack, the minimum length of wire that should be untwisted is typically around half an inch (1.27 cm). This limitation helps maintain the integrity of the twisted pairs, which are designed to reduce electromagnetic interference. Keeping the untwisted length to a minimum ensures optimal performance and signal quality in Ethernet connections.
