Which category of twisted pair cable is commonly used for Ethernet up to 1000 Mbps?

The ability to run Ethernet at 1 Gbps over copper hinges on the cable’s capacity to carry higher-frequency signals with minimal interference. Cat5e is designed to tighten crosstalk and noise specs while enabling all four twisted pairs to carry data simultaneously, which is exactly what 1000BASE-T (gigabit Ethernet) relies on. That combination—reduced interference and reliable high-frequency performance over a 100-meter link—makes Cat5e the standard choice for Ethernet speeds up to 1 Gbps. Cat5 is older and not guaranteed to meet those gigabit metrics, Cat3 is an even older, lower-speed category, and Cat7 offers more shielding and higher-frequency potential but isn’t the typical, cost-effective option used for standard 1 Gbps networks.
