This Section
Category 1 - It is an unshielded and untwisted wire. It has no rated frequency.

Category 2 - It is Unshielded and twisted into pairs. It has a rated frequency at 1 mhz. It offers an 100ohm impedance. We commonly use it for telephone systems

Category 3 - It is unshielded and twisted into pairs. It has a rated frequency of 16 mhz. It offers an 100ohm impedance. We commonly use it for telephone wiring and a 10Base-T connection (10 MBaud)

Category 4 - It is Unshielded and twisted into pairs. It has a rated frequency at 20 mhz. It offers an 100ohm impedance. We commonly use it for a 10Base-T connection (10 MBaud)

Category 5 - It is Unshielded and twisted into pairs. It has a rated frequency at 100 mhz. It offers an 100ohm impedance. We commonly use it for a 10Base-T (10 MBaud) and a 100Base-TX (125 MBaud) connection.

Category 5e - It is Unshielded and twisted into pairs. It has a rated frequency at 100 mhz. It offers an 100ohm impedance. We commonly use it for a 1000Base-T (125 MBaud), a 100Base-TX (125 MBaud) and a 10Base-T (10Mbaud) connection.

Category 6 - It is Unshielded and twisted into pairs. It has a rated frequency at 250 mhz. It offers an 100ohm impedance. We commonly use it for a 1000Base-T (125 MBaud), a 100Base-TX (125 MBaud) and a 10Base-T (10Mbaud) connection.
