Cat1
Voice grade; not suitable for networking. Maxium speed: n/a
CAT2
Digital telephone and low speed networks. Maxium speed: 4 Mbps
CAT3
Unshielded twisted pair capable of speeds up to 10Mbit/s. Used with 10Base-T, 100Base-T4, and 100Base-T2 Ethernet. CAT3 is currently used for telephone wiring.
CAT4
Unshielded twisted pair capable of speeds up to 20Mbit/s. Not widely used. Used with 10Base-T, 100Base-T4, and 100Base-T2 Ethernet.
CAT5
Unshielded twisted pair capable of speeds up to 100Mbit/s. May be used with 10Base-T, 100Base-T4, 100Base-T2, and 100Base-TX Ethernet.
CAT5e
Enhanced Cat 5 is similar to CAT5, but exceeds its performance. Improved distance over previous categories from 100m to 350m. May be used for 10Base-T, 100Base-T4, 100Base-T2, 100BaseTX and 1000Base-T Ethernet.
CAT6
Can transmit data up to 220m at gigabit speeds. It has improved specifications for NEXT (Near End Cross Talk), PSELFEXT (Power Sum Equal Level Far End Cross Talk), and Attenuation. Cat 6 is backward compatible with lower Category grades and supports the same Ethernet standards as Cat 5e.
CAT7
Gigabit Ethernet. Maximum speed: 1 GBPS+ Supports a signaling rate of 1 GHz.
