building a Cat 5 Cable

The steps below are general Ethernet cat5 cable construction guidelines. They will work for development any class of network cables. For our example we will be development a class 5e patch cable. A key point to remember in development Ethernet patch cords is that the “twists” in the individual pairs should remain entwined as long as potential until they reach the Rj-45 plug termination. The twisting of the pairs in the network cable is what helps to ensure good connectivity and keeps cross-talk interference to a minimum.

Step 1 - Stripping

Cable Tester

Start by pulling out about 12 feet of bulk network cable to development the process a small easier. Determined reMove the outer jacket of the cable exposing about 1 1/4" of the twisted pairs. Be truthful when stripping the jacket as to not nick or cut the internal wiring. After removing the outer case you will consideration 8 wires twisted in pairs and a rip cord (white thread).

Step 2 - Inspecting

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 execution or no connectivity at all. It is prominent that the jacket for all network cables remains intact.

Step 3 - Preparation

To get ready the wires and to make them easier to work with, you can untwist the pairs so they will lay flat in the middle of your fingers. The white piece of thread can be cut off even with the jacket and disposed.

Step 4 - Layout

Now based on the wiring specifications you are following you will need dispose the wires in a sure pattern. There are two methods set by the Tia, 568A and 568B. 568B is the most common network cables, widely used for computer networks and digital phone systems. So for our demonstration we will use that. Starting from the left-top side of the Rj-45 plug, the wiring should be in the order shown at the right.

Step 5 - Jack Preparation

Again, press all the wires flat in the middle of your thumb and forefinger as shown in step three. Verify the colors have remained in the definite order. Using a pair of scissors, cut the top of the wires even with one an additional one so that they are 1/2" long from the base of the jacket. Ensure that the cut leaves the wires even and clean; failure to do so may cause the wire not to make touch inside the jack.

Step 6 - Wire Insertion

Ensuring that the wires remain flat and in order, push them into the Rj-45 plug with the flat surface of the plug on top. The white / orange wire should be on the left seeing down at the jack. You can tell if all the wires made it into the jack and voice their positions by seeing head-on at the plug. You should be able to see a wire placed in each hole, as seen at the bottom right. You may have to use a small effort to push the pairs firmly into the plug. The cabling jacket should also enter the rear of the jack about 3/16" to help fetch the cable once the plug is crimped.

Step 7 - Crimping

Now place the wired plug into the crimping tool. Give the handle a firm squeeze, you should hear a ratcheting Noise as you continue. Once you have completed the crimp, the handle will reset to the open position.

Step 8 - Testing

Once your new cable is completed, it is not a bad idea to test the cable to ensure that it will function in the field. It is vital that all eight wires have connectivity and are in the definite order. Mis-wired network cables could lead to headaches down the road. In addition, with Power-over-ethernet development its way into the market place, crossed wire pairs could lead to corporal damage of computers or phone system equipment; development it even more crucial that the pairs are in the definite order. A easy cable tester can quickly verify that data for you.
