CAT 6 cables contain 4 pairs of copper wire and unlike Cat5e, utilizes all four pairs. CAT6 supports Gigabit (1000 Mbps) Ethernet and communications at more than twice the speed of CAT5e, the popular standard for Gigabit Ethernet cabling. By allowing a much higher frequency of signal, the bandwidth supported is much larger, allowing more network traffic than ever - perfect for transferring large files across networks or for high user traffic LAN use
