Although I got pretty good at it, I’ve still lost count over the years of the number of times I’ve had to snip an end off and start again from scratch, wasting a plug which can’t be used again and making the cable shorter and shorter with each failure. So, take your wire cutters and cut however much cable you need for the cable run you’re working on – being sure to leave a generous amount of excess, partly because a few centimetres will get chopped from either end, and because it’s always better to have a little bit of excess rather than realise the cable’s too short! Some crimping tools also include a cutter and a stripper, although I tend to use my own separate wire cutters and strippers – but it’s up to you. Well, there’s now a better way using a slightly different type of RJ45 plug and a different crimping tool. So, this guide will show you the easy way to fit an end and make up your own ethernet cables from start to finish. Where are you going to be running network cable? Do you use pass through RJ45 connectors or the older style ones? Let me know in the comments and you can also join the channel for some extra perks and technical support from me. It consists of 4 pairs of color-coded wires that are twisted around each other. This is done to prevent electromagnetic interference and distortion of the signal.
Would you like to see how one of these plugs is terminated? Take a look at How To: Terminate an Unshielded Pass Through RJ45 Connector . RJ45 connectors that will be interfacing with an Ethernet network have several technical considerations to keep in mind during design. At the board level, the focus is on reducing EMI, preserving electrical signal isolation, and maintaining signal integrity. Without diving too far into the details of circuit design, it is important to pay close attention to the length and position of traces on the board. Physical placement of the connectors on the PCB should also be considered. There are several applicable standards for RJ45 connectors, depending on their application and intended use. These applicable standards are briefly summarized here, but several standards will be outlined in greater detail later:
https://geni.us/RJ45PassThru– RJ45 plugs – make sure you buy pass through plugs, sometimes called snap plugs, and optionally the strain relief boots which help stop the little clip lever from snapping https://geni.us/Cat6– A drum of Ethernet cable – probably either Cat5e, Cat6 or possibly even Cat6a, it will depend on your use case but we won’t get into the differences in this article It is similar to a shielded twisted pair cable, but it has an extra layer of protection against electromagnetic interference. So there you have it! All about the simple, ho-hum RJ45 connector plug. Not quite as simple and ho-hum as people may think! Knowing is half the battle, and hopefully you will get a chance to terminate some of these connectors yourself. There is no substitute for “hands-on” experience.
No, RJ45 and CAT6 are not the same. The RJ45 is a connector, while CAT6 (CATEGORY 6) is a model of twisted-pair cables. But, CAT cables are commonly referred to as RJ45 cables or Ethernet cables. Applications of RJ45 cables RJ45, modular plug, 8P8C, end, connector... these terms are used interchangeably. These all describe the piece attached to the end of an Ethernet cable that plugs into your TV, computer, router, etc. A variety of other standards define the cables or wires utilized for RJ45 devices, again largely depending on the end application. Ethernet and EtherCATWhat’s interesting is the confusion surrounding this unassuming little part. The very name can generate confusion. https://geni.us/NetworkCableTester– Finally, a Cable tester – this is essential to verify the cable and all 8 connections are correct and working before you go to use it in your network setup. Knowing how to wire an RJ45 connector plug means that you can cut your Ethernet cable to custom lengths. This is handy for neatly managing cables or creating very long runs Here’s the RJ45 Pinout T-568B diagram which was the first result in Google Images in the video demo: https://www.showmecables.com/blog/post/rj45-pinout As Cat 9 and 10 will surely come along, it's worth wondering what the next generation of wired connectivity will look like. Many homes already get blazing internet speeds via Fiber to the Home (FTTH), but the current technology limits them to copper Ethernet cables to then connect to the router, access points and other networking accessories. The next step could be to extend fiber's reach to inside the home with the ability to carry thousands of times more data than copper wires can today.
Wiring your own male RJ45 plugs to the end of a suitable network communication cable requires just a few simple tools. Fixing a new connector is usually cheaper than replacing an entire Ethernet cable. Other reasons you may want to wire them yourself include: RJ45 cables are commonly used in Ethernet connections. Yet, they are useful for other applications also. For example: Although it's not recognized by the Telecommunications Industry Association (TIA), Category 7 cable debuted in 2010 and is aimed at data centers and server rooms where top speed counts. Each cable is double-shielded: around each pair of wires and an overall shield around the entire bundle of wires. This extra isolation is needed because the 600MHz frequency used can push a maximum of 10Gbps over 330 feet. More recently, the introduction of Cat 7A cable increases the speed to 1GHz and throughput to 40Gbps, but tops out at 165 feet. Cat 8 Cable: The new 2GHz speed limit As visible in the figure above, both connectors at the ends of the cable have different standards. One side of the cable is connected in T568-B standard, while the other is connected in T568-A standard. What are the different categories of twisted pair cables?
RJ45 Cable for Ethernet Connections
In modern domestic and commercial environments, RJ45 connectors are primarily used for plugging an internet-enabled device directly into hardware such as a modem, router, or server. The connectors themselves are the modular sets of fittings at either end of the physical data connection (Ethernet cable) joining one networked device to another.
