An office is upgrading to 10 Gigabit Ethernet over copper cabling and wants to keep the same 100-meter horizontal run through a plenum ceiling. To guarantee the full 10 Gbps speed end-to-end and reduce alien crosstalk, which twisted-pair cable type should the technician specify for the new pull?
Category 6a (Augmented Cat 6) is rated for 10 GBASE-T over the full 100-meter channel and is designed with tighter twists and, often, additional shielding or a separator to reduce alien crosstalk at the higher 500 MHz signaling required for 10 Gbps. Standard Cat 6 can handle 10 Gbps only to about 55 meters, Cat 5e tops out at 1 Gbps, and RG-6 is a coaxial cable not used for twisted-pair Ethernet runs.
