I am wondering if anyone knows if I am able to put a CAT5 plug/jack onto my CAT6 wire. I currently have no need for CAT6 speeds and I already have many cat5 plugs(but only have cat6 wire). Is there any great disadvantage to doing this?? I figured that when I need CAT 6 capabilities I can just purchase cat6 plugs at that time and swap them out. Thanks for all your time!!

From what I understand there is only one standard connector, the RJ45 (the connector that looks like a telephone with 6 wire spots, you've used it with cat5) connector. So yes, you can use an RJ45 connector with cat6 cabling. The cat6 cablind is just a higher grade cabling but uses the same termination end points as regular cat5/cat5e cabling.

If there is only one standard RJ45 connector, then why do companies specify plugs & connectors seperately for CAT5, CAT5e, and CAT6? (also whith such a price difference between them all) Still isn't completely clear to me. Thanks for your relpies and time!!!

Can you show me some example links. Honestly i havn't been doing any networking lately, been focusing on marketing, so I could be rusty, but I was under the assumption there was only 1 type of RJ45 plug.

steveoberly, are you sure you saw different items for cat6 rj45 connectors? The RJ45 connector is an industry standard network jack. The cable can be changed such as Cat5, Cat5e, Cat6, even your regular old phone able, can all be used with the RJ45 connector. Ive never heard of a specialty connector for cat6 cable. Reason being, is that the RJ45 is, as i said, industry standard so it fits into network cards and computer systems. If they changed the plug, then it would not fit into computer systems and networks.

So I think what you might have seen was a cat6 grouping with rj45 connectors included, but you will most definitly be fine using cat6 (or any Category cable) with an RJ45 connector.

Adam,
With your help and my own research of my concern about the differences, I feel I've come to a 'content' conclusion of the matter. However, you asked for a link that was marketing CAT5,5e & Cat6 as different items; and I wanted to foreward those to you.
Lanshack is one of the many sites I've found that sold both plugs and jacks for these wires. In all the sites I have not found an item that states that it is intended to be installed on all types...... ie: no item states anything that gives the impression:"fits CAT5 & CAT6...or UNIVERSAL"
Again, I greatly appreciate your reply & effort!!!

The difference between the two styles of plugs would be backwards from your conversation.

A Cat5E or Cat6 connector can be used on both types of cables, the difference would be maximum bandwidth. The Cat5E connector would not handle (theoretically) the Cat6 bandwidth levels. Placing Cat6 connectors on Cat5E cable provides no issues.

Cat6 cable is rated at twice the available bandwidth (Cat5E at 100MHz and Cat6 at 200MHz).

Cat 5 is a 4-pair cable but only uses 2 pr up to 100 meters 10/100
Cat 5e is a 4-pair cable but uses 4 pr up to 100 meters 10/100/1000
Cat 6 is also a 4-pair cable, that uses 4 pr. up to 100 meters 10/100/1000

All "CAT"s are available in stranded or solid core wire.
Stranded is more flexible but better suited for shorter runs.
Solid is less flexible but will work better over longer runs.

All use the common RJ45 plugs and jacks. Some connecting plugs and jacks are "supposedly" better suited for higher speed by having different contact materials .. ie gold plated etc.

The CAT6 twisted pairs are twisted at a higher twist rate than Cat5. For example instead of 5 twists per inch they may be 10 twists per inch. (only an example) The tighter twist is (from what I remember) to decrease cross talk or data contamination between pairs because of the higher data transfer rate.

For what it's worth, I have successfully used Leviton cat 5e jacks with cat 6 cable. I originally thought it wasn't working myself due to unknown issues (probably related to lack of sleep!) and emailed Leviton. They replied that their 5/5e jacks will work with Cat 6. I re-punched everything in what I though was exactly the way I had it before (several times) and voila, now it worked!!! I guess 'belief' was all I lacked!! Laughing
