Ethernet Cable – Color Coding Diagram. The information listed here is to assist Network Administrators in the color coding of Ethernet cables. Please be aware that modifying Ethernet cables improperly may cause loss of network connectivity. Use this information at your own risk, and insure all connectors and cables are modified in accordance with standards. The Internet Centre and its affiliates cannot be held liable for the use of this information in whole or in part. T- 5. 68. A Straight- Through Ethernet Cable. The TIA/EIA 5. 68- A standard which was ratified in 1. TIA/EIA 5. 68- B standard in 2. Both standards define the T- 5. A and T- 5. 68. B pin- outs for using Unshielded Twisted Pair cable and RJ- 4. Ethernet connectivity. The standards and pin- out specification appear to be related and interchangeable, but are not the same and should not be used interchangeably. T- 5. 68. B Straight- Through Ethernet Cable. Both the T- 5. 68. A and the T- 5. 68. B standard Straight- Through cables are used most often as patch cords for your Ethernet connections. ![]() ![]() 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. RJ- 4. 5 Crossover Ethernet Cable. A good way of remembering how to wire a Crossover Ethernet cable is to wire one end using the T- 5. A standard and the other end using the T- 5. B 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. Specifically, switch the solid Green (G) with the solid Orange, and switch the green/white with the orange/white. Ethernet Cable Instructions: Pull the cable off the reel to the desired length and cut. If you are pulling cables through holes, its easier to attach the RJ- 4. The total length of wire segments between a PC and a hub or between two PC’s cannot exceed 1. Meters (3. 28 feet) for 1. BASE- TX and 3. 00 Meters for 1. BASE- T. Start on one end and strip the cable jacket off (about 1. 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. Trim the ends of the wires so they are even with one another, leaving only 1/2. If it is longer than 1/2. Flatten and insure there are no spaces between wires. Hold the RJ- 4. 5 plug with the clip facing down or away from you. ![]() How to make a Cat5, Cat5e or Cat6 patch or crossover cable Darren Chew 12 July 2016 09:40. Cat5, Cat5e and Cat6 (simply. To make a cross over cable. 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. Check that the jacket is fitted right against the stop of the plug. Carefully hold the wire and firmly crimp the RJ- 4. 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. ![]() Odd numbered pins are always striped, even numbered pins are always solid colored. Looking at the RJ- 4. Brown is always on the right, and pin 1 is on the left. Save yourself some money and make your own Ethernet CAT5 RJ45 Crossover. How to install an RJ45 connector on a CAT5 Ethernet network Patch Cable.No more than 1/2. 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. What you may not realize is that, these same pins 4, 5, 7, and 8 are not used or required in 1. BASE- TX as well. 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- 4.
