How to Make a Network Cable...?

STEP-

1- Unroll the required length of network cable and add a little extra wire, just in case. If a boot is to be fitted, do so before stripping away the sleeve and ensure the boot faces the correct way.

2-Carefully remove the outer jacket of the cable. Be careful when stripping the jacket as to not nick or cut the internal wiring. One good way to do this is to cut lengthwise with snips or a knife along the side of the cable, away from yourself, about an inch toward the open end. This reduces the risk of nicking the wires' insulation. Locate the string inside with the wires, or if no string is found, use the wires themselves to unzip the sheath of the cable by holding the sheath in one hand and pulling sideways with the string or wire. Cut away the unzipped sheath and cut the twisted pairs about 1 1/4" (30 mm). You will notice 8 wires twisted in 4 pairs. Each pair will have one wire of a certain color and another wire that is white with a colored stripe matching its partner (this wire is called a tracer).

3- Inspect the newly revealed wires for any cuts or scrapes that expose the copper wire inside. If you have breached the protective sheath of any wire, you will need to cut the entire segment of wires off and start over at step one. Exposed copper wire will lead to cross talk, poor performance or no connectivity at all. It is important that the jacket for all network cables remains intact.

4- Untwist the pairs so they will lay flat between your fingers. The white piece of thread can be cut off even with the jacket and disposed (see Warnings). For easier handling, cut the wires so that they are 3/4" (19 mm) long from the base of the jacket and even in length.

5-Arrange the wires based on the wiring specifications you are following. There are two methods set by the TIA, 568A and 568B. Which one you use will depend on what is being connected. A straightthrough cable is used to connect two different layer devices (e.g. a hub and a PC). Two like devices normally require a crossover cable. The difference between the two is that a straightthrough
cable has both ends wired identically with 568B, while a crossover cable has one end wired 568A and the other end wired 568B.[1] For our demonstration in the following steps, we will use 568B, but the instructions can easily be adapted to 568A.568B Put the wires in the following order,

From left to
right:
white orange

white green

6-You can also use the mnemonic 1236/3612to remember which wires are switched.

7-Press all the wires flat and parallel between your thumb and forefinger. Verify the colors have remained in the correct order. Cut the top of the wires even with one another so that they are 1/2" (12.5 mm) long from the base of the jacket, as the jacket needs to go into the 8P8C connector by about 1/8", meaning that you only have a 1/2"of room for the individual cables. Leaving more than 1/2" untwisted can jeopardize connectivity and quality. Ensure that the cut leaves the wires even and clean; failure to do so may cause the wire not to make contact inside the jack and could lead to wrongly guided cores inside the plug.

8-Keep the wires flat and in order as you push them into the RJ45plug with the flat surface of the plug ontop. The white/orange wire should be on the left if you're looking down at the jack. You can tell if all the wiresmade it into the jack and maintain their positions by looking headon at the plug. You should be able to see a wire located in each hole, as seen at the bottom right. You may have to use a little effort to push the pairs firmly into the plug. The cabling jacket should also enter the rear of the jack about 1/4" (6 mm) to help secure the cable once the plug is crimped. You may need to stretch the sleeve to the proper length. Verify that the sequence is still correct before crimping.

9-Place the wired plug into the crimping tool. Give the handle a firm squeeze. You should hear a ratcheting noiseas you continue. Once you have completed the crimp, the handle will reset to the open position. To ensure all pins are set, some prefer to doublecrimpby repeating this step.

10-Repeat all of the above steps with the other end of the cable. The way you wire the other end (568A or568B) will depend on whether you're making a straightthrough, rollover, or cross over cable .
11-Test the cable to ensure that it will function in the field. Misunderstand incomplete network cables could lead to headaches down the road. In addition, with power over Ethernet (PoE) making its way into themarketplace, crossed wire pairs could lead to physical damage of computers or phone system equipment, making it even more crucial that the pairs are in the correct order. A simple cable tester can quickly verify that information foryou. Should you not have a network cable tester on hand, simply test connectivity pin to pin.
