CAT6 cables reduce crosstalk and system noise. The superior insulation around the 23 AWG copper wires attribute to the increased performance. They can transmit data at 1000 Mbps (~1 Gigabit per second) with a frequency of 250 MHz and suitable for 10BASE-T, 100BASE-TX Fast Ethernet and 1000BASE-T / 1000BASE-TX (Gigabit Ethernet). The shield reduces electrical noise from affecting the signals, and to reduce electromagnetic radiation that may interfere with other devicesCAT6 SFTP Cable supports Gigabit Ethernet (1000 Base-T) standard. Operates at a bandwidth up to 250 Mhz. Tinned Copper Screening gives protection against EMI and avoid signal loss. Better Mechanical Properties of cable. This cable well exceeds the requirements of TIA/EIA-568.C.2
