That is why cat5e cables are faster than cat5 cables. Still no fiber connection, though. But cat6 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. You can learn more about CAT 6 cables here. The connector used for twisted-pair Ethernet cables is called RJ45 connectors. RJ45 is a connector with 8 pins. One for each wire in a typical Ethernet cable with 4 pairs of wires. The RJ45 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 RJ45 pinout looks:. When you make an Ethernet cable it is important to know where each pin is.
Because, when you connect an Ethernet cable to an RJ45 connector you will be using a crimp tool. When you have crimped the connector there is no way back.
Make sure to have some connectors for practice. As with the cables UTP simply means shielded twisted pair. This is because the UTP connectors have no shield, and are entirely made out of plastic. The RJ45 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. The pins in an RJ45 connector are made with a sharp edge to cut into the wires and thereby making an electrical connection.
But the STP connector has a metal shield or metal housing around the connector. A pack of costs can be purchased on Amazon. To make the electrical connection we need to insert the wires in the RJ45 connector and press down the pins. This is done with the RJ45 crimp tool. The tool will also apply pressure to the opening of the connector, to secure the cable. You can pick up a quality but cheap RJ45 crimp tool here on Amazon.
Or you can read reviews on the best RJ45 crimper on the market. The wiring of Ethernet cables can be done in several ways. Two of the most common ways are by following the TA and B standards. The reason for using these standards is that the signals will run in the pairs of wires; in a way that takes advantage of the noise-canceling effect of twisted wires.
Using the standards also makes it very easy to make a crossover Ethernet cable. The first wiring standard is the TA. It is also referred to just as A. Each wire color has its own pin number position. TB is the other standard. The difference from the A standard is that the orange and green pairs are swapped. You can see the TB wiring below:. Source: Wikipedia. Ethernet cables can be made in two different ways. The first way is called straight-through and is the simplest one.
Straight-through means that the cable is wired equally in both ends. The wires go from one pin number to the same pin number. As long as you use the same standard in both ends of your cable. If you are extending an existing network, you should always check which wire standard is used for straight-through cables and continue that. Also, you should be consistent in your choice, and so using the same standard for all your cables.
The second type of cable you can make is the crossover Ethernet cable. Ethernet crossover cables are made for one special reason. Namely to swap the wires used for sending and receiving data. For example in an RJ45 connector on a computer, each pin has a defined function. Two of the pins are for sending data, and two of the pins are for receiving data. When you want to connect two computers you are going to need an Ethernet crossover cable. Swapping the two wires for sending and receiving data at one end of the cable, will make the right connections.
You will make a connection between the pins used for sending in the one computer and the pins used for receiving on the other computer. The most common way to make an Ethernet crossover cable is to use TA in one end of the cable and use TB at the other end of the cable.
This is the other reason that these standards are so useful. Because the difference between the A and B standard is two swapped wire pairs. The exact pairs used for sending and receiving data. The wiring diagram above shows how an Ethernet crossover cable looks like. The crossover cable is connected with the A and B standard in each end. There are some things in life that are too complex or dangerous to make yourself — such as a whole house surge protector or electrical circuit tracer.
An ethernet cable is not one of these things. Well before you make up your mind, take a look at the video tutorials below or read the step by step guide below on how to make an Ethernet cable.
Remember, it can be tricky in the beginning, especially with the thick wires. But practice makes better, and eventually, you will even start to enjoy making Ethernet cables. Nice site. I have been programming PLC for over 25 years, and I appreciate your effort. You could put some the limitations for E-net cable:.
Ethernet over copper networks are limited to a data distance of only meters ft when using unshielded twisted pair UTP or sheilded twisted pair STP cable. By using an Ethernet to Fiber Optic Converter , fiber cabling can be used to extend data connections over a much greater distance. They can also be used in environments with high levels of electromagnetic interference EMI which is commonly found in industrial environments.
This interference can cause corruption of data over copper Ethernet lines. However, data over fiber is immune to this type of noise. An Ethernet to Fiber Optic Con verter enables you to inter-connect your copper Ethernet devices over fiber ensuring optimal data transmission across the entire long distance network. Media converters can connect to various fiber optic cable types such as multimode or single mode. Many different pre-made fiber lengths are available and are perfect for your Ethernet to fiber application.
Thanks for your comment! I really appreciate your ideas. Using an Ethernet to fiber optic converter for longer distances and noisy environments are a great idea. I will give this its own article, since fiber optics is a larger subject. Have you ever used those converters in a PLC network? If you are going to make longer Ethernet cables you should use twisted pair cables with the highest AWG number.
Therefore, you need the lowest AWG number possible when using them over long distances. Ethernet over twisted pair The Ethernet networks use twisted-pair cables for wired communications. Caution: Make sure to push wires as far back as they will go into the 4-pin wire splicers to ensure a proper signal flow and avoid malfunctioning cables. Usually you should try to match the color of the cables for best appearance.
I only had red tape! You now have a hopefully working 9-pin serial to Ethernet cable. If there is a problem, it usually has something to do with mapping designated pins with correct inner cables. First, try to re-crimp the 4-wire splice connectors to ensure a solid connection. Then go back and check your cable mappings. Think of all the other cables you can cross with an Ethernet cable! If you don't want to waste your time and need to share the single serial device quickly, you may use the software Serial to Ethernet solution.
Reply 5 years ago. The title is somewhat misleading. This isn't a serial to Ethernet cable; it's a 9-pin D shell to RJ45 cable with no serial to Ethernet protocol conversion. Did you make this project? Share it with us!
