how fast is a standard ethernet cable
Need for Speed. Ethernet speed first increased with the change from coaxial cable to twisted pair copper cables on the CAT5 standard. This allowed connections to transmit at 10 Mbps. Fast Ethernet was introduced in 1995 and allowed transmissions of up to 100 Mbps. Further developments saw the technology cross several more speed barriers: for example, 1 gigabyte per second (Gbps), 10 Gbps, 40 Gbps, and finally 100 Gbps.
