Patch cable color management pdf
Please be aware that modifying Ethernet cables improperly may cause loss of network connectivity. Use this information at your own risk, and ensure all connectors and cables are modified in accordance with TIA standards.
You can also see that both the blue and brown wire pairs on pins 4, 5, 7, and 8 are not used in either standard. So why bother using these wires, well for one thing its simply easier to make a connection with all the wires grouped together.
Otherwise you'll be spending time trying to fit those tiny little wires into each of the corresponding holes in the RJ connector. The TA standard is supposed to be used in new network installations. Most off-the-shelf Ethernet cables are still of the TB standard; however, it makes absolutely no functional difference in which you choose. If you require a cable to connect two Ethernet devices directly together without a hub or when you connect two hubs together, you will need to use a Crossover cable instead.
A good way of remembering how to wire a Crossover Ethernet cable is to wire one end using the TA standard and the other end using the TB standard.
Another way of remembering the color coding is to simply switch the Green set of wires in place with the Orange set of wires. Live Help Desk. Fiber Optics. Fiber Optic Patch Cables. Termination Kits.

If you are pulling cables through holes, it's easier to attach the RJ plugs after the cable is pulled.
Start on one end and strip the cable jacket off about 1" using a wire stripper or a knife. Be extra careful not to nick the wires, otherwise you will need to start over.
Spread, untwist the pairs, and arrange the wires in the order of the desired cable end. Flatten the end between your thumb and forefinger. Flatten and insure there are no spaces between wires. Hold the RJ plug with the clip facing down or away from you. Push the wires firmly into the plug. Inspect each wire is flat even at the front of the plug. Check the order of the wires. Double check again. Check that the jacket is fitted right against the stop of the plug.
Carefully hold the wire and firmly crimp the RJ with the crimp tool.

Check the color orientation, check that the crimped connection is not about to come apart, and check to see if the wires are flat against the front of the plug. If even one of these are incorrect, you will have to start over. Test the Ethernet cable. Ethernet Cable Tips : A straight-thru cable has identical ends.

A crossover cable has different ends. A straight-thru is used as a patch cord in Ethernet connections. A crossover is used to connect two Ethernet devices without a hub or for connecting two hubs. A crossover has one end with the Orange set of wires switched with the Green set.
Straight Through vs Crossover Cable
Odd numbered pins are always striped, even numbered pins are always solid colored. Looking at the RJ with the clip facing away from you, Brown is always on the right, and pin 1 is on the left. Do not deform, do not bend, do not stretch, do not staple, do not run parallel with power cables, and do not run Ethernet cables near noise inducing components.
