Detailed explanation-1: -Cat 5e supporst 1 Gbps (1, 000 Mbps) for cables up to 100 meters long (a little over 300 feet). Cat 6 adds 10 Gbps (10, 000 Mbps) if the cable is up to 50 meters long. Cat 6a adds 10 Gbps for cables up to 100 meters long. 1 Gbps doesn’t need any greater bandwidth than 100 Mbps.
Detailed explanation-2: -What is the minimum cable specification that supports 1000 Mbps Ethernet? cat 3 & 4 only support 10 Mbps. cat 5 cable only supports 100 Mbps. cat 6 or 7 is required for bandwidth up to 10 Gbps.
Detailed explanation-3: -1000BASE-T (also known as IEEE 802.3ab) is a standard for Gigabit Ethernet over copper wiring. Each 1000BASE-T network segment is recommended to be a maximum length of 100 meters (330 feet), and must use Category 5 cable or better (including Cat 5e and Cat 6).
Detailed explanation-4: -Introduced in 1995, Category 5 cable has a data rate of up to 100 Mbps. It is used for standard 10BaseT and 100BaseT (Fast Ethernet) networks, and can distribute data, video and telephone signals at distances up to 100 meters (328 ft.).
