You can also find other RJ standard type connectors out there like RJ11, RJ14, RJ25, etc, where they all have different sizes and functions. Being a physical standard, it sets a standard for the wiring patterns used for the RJ45 connector. RJ45 stands for registered jack 45, where the number 45 simply denotes the standard shape of this connector.Īs for the registered jack part, it simply means that RJ45 is a physical standard used for network interfaces in all kinds of applications. While we have already stated and explained some of the major importance of the RJ45 connector, some of you might be interested in knowing more about its name as well. You can learn more about the RJ45 connector by going through the following factors one by one: RJ Stands for Registered Jack As for its modern applications, it is primarily used for connecting computers to a LAN network. It is a modular connector for telecommunications and networking that can be adjusted as per your needs. This simply means that it has a total of eight positions and eight conductors. The complete name of the RJ45 connector happens to be the RJ45 8P8C plug. An RJ45 connector is a highly popular physical connector used for networking applications that was primarily made for telephones. This also includes the RJ45 connector, which is primarily used for Ethernet connections between the various devices in any given wired network. The differences in color conventions are shown in the chart below.If you are new to wired networking, then you are most probably unfamiliar with the different devices and connectors used in it. Over time, T568B has become more popular. These wiring layouts each have their own color convention, and following the convention is important to ensure electrical compatibility. Now, the T568A and T568B pinouts mentioned above define the arrangement of the eight individual wires in the connector. As such, for the sake of clarity, we will refer to them as modern RJ45 connectors. There are two RJ45 pinouts (T568A and T568B), and even though they are technically 8P8C connectors, it is very likely you will hear them strictly referred to as RJ45 connectors, and all documentation surrounding them will use the same terminology. This mistaken use of terminology is widespread throughout the industry, and though it is unlikely to change anytime soon, there really isn’t much reason for concern nearly everyone is collectively making the same mistake, and those who are in the know more often than not simply use RJ45 to avoid confusion or argument.Īn example of this is clearly visible in the “RJ45” Ethernet connectors. Today, almost all electronic equipment using 8P8C connectors will show documentation for RJ45 connectors, which is technically incorrect. Therefore, what most of the industry refers to as RJ45 connectors are in fact 8P8C modular connectors. However, because the connectors resemble each other so closely in appearance, the groups and individuals who transitioned from telephone networking to computer networking started to mistakenly call the unkeyed 8P8C connectors “RJ45s” and the terminology quickly caught on. The connectors are not entirely compatible with one another because of the keying used in RJ45 8P8C connectors can plug into RJ45 receptacles, but the inverse is not true. The differences between 8P8C connectors and RJ45 connectors are shown in the following diagram: There are a variety of 8P8C connectors out there, with the modern RJ45 Ethernet connector being the most prevalent.Īs a result of the close similarities, “RJ45” became the designated informal misnomer for any eight-pinned jack (8P8C modular connector) used in computer networking (Ethernet). Individual wires are then inserted into these positions. In 8P8C connectors, each plug has eight positions that are spaced approximately 1 mm apart. 8P8C ConfusionĨP8C refers to the array of pins, hence the name Eight Position, Eight Contact. With the advent of computer networking, a new but very similar connector was developed to carry out data transfer: 8P8C. The connectors of the RJ platform were developed as much smaller and cheaper replacements to the older telephone installation methods of hardwired cords or bulky plugs. RJ stands for “registered jack,” and the true RJ45 connector was originally developed as part of the standardized telecommunication network interface for the purpose of connecting telephone networks. Let’s start with RJ45, perhaps the term most widely used to refer to Ethernet cables today.
