What is the minimum category of cable required to achieve speeds of 10mbps?

The minimum category of cable required to achieve speeds of 10 Mbps is Category 3 (Cat 3) cable. Cat 3 cables can support data rates up to 10 Mbps over distances up to 100 meters. However, for better performance and future-proofing, using Category 5 (Cat 5) or higher is recommended, as they support much higher speeds and bandwidth.
