A Cat 6 UTP (Unshielded Twisted Pair) cable supports the following speeds and distances:
1 Gbps (Gigabit Ethernet) up to 100 meters (328 feet)
10 Gbps (10-Gigabit Ethernet) up to 55 meters (180 feet)
250 MHz bandwidth
For full 10 Gbps performance up to 100 meters, you’d need Cat 6A (Augmented Cat 6).
