Twisted pair Cable categories for 1 Gigbit and 10 Gigabit Ethernet networks
While selecting twisted pair cables for 1 Gbps and 10 Gbps networks, you need to remember following facts related with twisted pair categories. For 1 Gbps and 10 Gbps networks, you need twisted pair cables of category 5e or above.
Please note below facts.
Category 5e twisted pair cables support only 1 Gbps Ethernet. Category 5e twisted pair cables do not support 10 Gbps Ethernet. So, 10 Gbps network may run only at slower bandwidth speeds with Cat 5e twisted pair cables, or support only less cable distance for data transmission.
Category 6 twisted pair cables support Ethernet (10 Mbps), FastEthernet (100 Mbps), Gigabit Ethernet (1 Gbps) and 10 Gigabit Ethernet (10 Gbps). For Ethernet (10 Mbps), FastEthernet (100 Mbps) and Gigabit Ethernet (1 Gbps), maximum distance supported by Category 6 twisted pair cable is 100 meters and for 10 Gigabit Ethernet (10 Gbps) maximum length supported is 55 meters.
Category 6a and Category 7 twisted pair cables supports both Gigabit Ethernet (1 Gbps) and 10 Gigabit Ethernet (10 Gbps) up to a distance of 100 meters.
