DO NOT post questions here that seek a response. That is the purpose of the forums and there is one where you can ask your question and get quick answers. You won't get them here, or by leaving feedback. The FAQs are for frequently asked questions that are applicable to many people.

Examples of what NOT to ask here:

"I have ----- service, but it won't connect. Why?"
"Is there a way I can use ------ with -------?"
"Why is my service doing this or acting like that?"

We want you to get an accurate and prompt answer. If questions like these are posted in the various forums on the site, they are seen almost immediately by our many expert members, and they will receive answers relatively quickly. This is also a better choice because if you're not sure of the answer, you can continue to discuss the issue and get additional help. Probably the best forum to start in, if you're not sure, is the General Questions forum. Don't worry ... if that doesn't turn out to be the best place, your question will be moved to a more appropriate forum.

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.
