Utp Patch Cable Pinout' title='Utp Patch Cable Pinout' />How to Make an Ethernet Cable. This is my guide on how to make an Ethernet cable. Often just referred to as a network cable or patch cable. Making your own Ethernet cables will not only cut down the price of your cables. You can also make the Ethernet cables in the exact length and with the exact wiring you need. Use this guide if you are making Ethernet cables for personal or professional use. Utp Patch Cable Pinout' title='Utp Patch Cable Pinout' />First, some information about the Ethernet cables, connectors and wiring. If you are already familiar with this, you can go straight to the guide How to make an Ethernet cable . What is an Ethernet cable An Ethernet cable is a the cables used to connect devices in an Ethernet network. The Ethernet cables are used for wired data transmission between the devices. Utp Patch Cable Pinout' title='Utp Patch Cable Pinout' />The Ethernet is a series of standards for communication between devices like computers. You probably know it from your own local area network. This adapter will enable you to connect a 25 pin male serial cable to a 9 pin female serial connector on your computer.

UTP cables are terminated with standard connectors plugs and jacks or punchdowns. The plugjack is often referred to as a RJ.

This article covers the commonly known Unshielded Twisted Pair UTP cable and shows how many pairs the UTP Cat5, Cat5e, Cat6 Cat7 cables consists of, the colour. The Ethernet standards are used in most computers, both personal computers and servers. But you can also find the Ethernet standards in the automation industry. As an example of that PROFINET the sister to PROFIBUS uses the Ethernet over twisted pair cabling to communicate between PLCs. Ehernet over twisted pair is what we are going to use to make an Ethernet cable. Ethernet over twisted pair. The Ethernet networks use twisted pair cables for wired communications. Twisted pair cables are cables where the wires inside are twisted along the cable in pairs. The reason for twisting the wires in pairs are to cancel out any electrical noise or interference from outside. Also known as EMI. Network are usually vulnerable to noise. Especially when the commutation is over longer distances. Twisting the wires in pairs is done to do differential mode transmission on the signals to equal out the noise. There are several types of twisted pair Ethernet cables are available. The UTP, STP and some others. They are all different and used in different environments depending on the level of electrical interference. UTP cables. UTP means Unshielded Twised Pair. These cables are without a shield around the wires or the wire pairs. UTP cables are sometimes used for patch cables in home or office environments. But they are never used in industrial or noisy environments, because they are vulnerable to noise. Even though the wires are twisted, the signals are still vulnerable to in environments with a lot of electrical interference. STP cables. STP means Shielded Twisted Pair. STP cables is a commonly used name for all the shielded twisted pair cables. Depending on how the shielding is done in the cable, you can get several types of twisted pair cables with shield. STP refers to all the cables with either a shield or a foil to protect the signals from noise. Besides the shield, foil is also used in twisted pair cables. Foil or FTP Foiled Twisted Pair is a layer of metal foiled around either all the wires, all the pairs of wires or both. All these types of twisted pair cables are available with different specifications. The cables are available with standed wires or solid core wires. Standed wires are flexible wires. This is because the wires are divided in many smaller wires. On the other hand solid core wires are solid wires and are not very flexible. Solid core wires are usually used in fixed installation. Twisted pair cable comes with different wire thickness. The usual ones are 2. AWG. If you are going to make longer Ethernet cables you should use twisted pair cables with the highest AWG number. As the cables get longer, so does the resistance. If you use thicker wires the resistance will be lower. Remember, the higher the resistance, the slower your network connection will be. Ethernet cable categories Cat cables. The cables used for making Ethernet cables are divided into categories. Each category is defined by the available bandwith and used for different purposes. For example category 3 or cat. All the cable categories for twisted pair cables are defined in ISO 1. The Ethernet cables this guide aims for are the ones using RJ4. They are the ones you can make by yourself. For that, you will be using one of the following cable categories. Cat. 5 Ethernet cable. Used for short distances in LAN 1. Base Tx. Category 5 cables or cat. Ethernet cables are normally used in noise safe environments. They can support up to 1. Mbits. Since cat. Ethernet cables, cat. Ethernet cable you can make. Cat. 5e Ethernet cable. Getting a little better with faster transmission speed 1. Base T. This category is a subcategory or an extension of category 5. This category has almost the same specifications as cat. This makes faster network speed available. That is why cat. 5e cables are faster than cat. Cat. 6 Ethernet cable. Now, we are thereSuitable for up to 1. GBASE T. Providing up to 1. Gbits, category 6 cables are the fastest ones. Still no fiber connection, though. But cat. 6 cables are the fastest Ethernet cables you can make. You can see a comparison of the cable categories 3 to 7, which are used for Ethernet. RJ4. 5 connector. The connector used for twisted pair Ethernet cables are called RJ4. RJ4. 5 is the common name, but they can also be referred to as 8 Position 8 Contact or 8. P8. C. RJ4. 5 is a connector with 8 pins. One for each wire in a typical Ethernet cable with 4 pairs of wires. The RJ4. 5 connector is a one way connector. This means that on top of the connector there is a small  you can only connect it in one way. Here is how the RJ4. When you make an Ethernet cable it is important to know where each pin is. Because, when you connect an Ethernet cable to a RJ4. When you have crimped the connector there is no way back. So the wires better be in the correct place, or youll have start over again. Make sure to have some connectors for practice. RJ4. 5 UTP connector. The first type of RJ4. Ethernet cables are the UTP connector. As with the cables UTP simply means shielded twisted pair. This is because the UTP connectors has no shield, and are entirely made out of plastic. The RJ4. 5 UTP connector is the simplest one to work with, since you do not have to worry about the shield. You can use it with both shielded and shielded twisted pair cables. UTP connectors are only 8. Amazon. The pins in a RJ4. RJ4. 5 STP connector. The other option you have, when you are making your Ethernet cable is the RJ4. STP connector. The STP connector is made out of plastic just like the UTP connector. But the STP connector has a metal shield or metal housing around the connector. A pack of 1. 00 costs only 1. Amazon. RJ4. 5 crimp tool. To make the electrical connection we need to insert the wires in the RJ4. This is done with the RJ4. The tool will also apply pressure to the opening of the connector, to secure the cable. The one below is cheap but good and can be bought here on Amazon. Ethernet Cable Wiring. The wiring of Ethernet cables can be done in several ways. Two of the most common ways are by following the T5. A and B standards. The reason for using these standards are that the signals will run in the pairs of wires in a way that takes advantage of the noise cancelling effect of twisted wires. Using the standards also makes it very easy to make a crossover Ethernet cable. T5. 68. A Wiring. The first wiring standard is the T5. A. It is also referred to just as A. Each wire color has its own pin number position. Here is how the T5. A wiring to a RJ4. Source Wikipedia. T5. 68. B Wiring. T5. 68. B is the other standard. The difference from the A standard is that the orange and green pairs are swapped. Cs Cheat. Pin Serial Adapter Pinout. This adapter will enable you to connect a 2. Carrier Detect. Receive Data.
