Cat6 terminates with RJ45 connectors and supports 10BASE-T, 100BASE-T, and 1000BASE-T standards. In high-performance applications, shielded Cat6 (F/UTP or S/FTP) with shielded keystone jacks and patch panels may be specified where electromagnetic interference (EMI) is a concern — common in Dallas-area industrial buildings, medical offices, or facilities near heavy electrical equipment.
