Telephone and broadband connections are two of the most prevalent network communications available worldwide. You can find them in almost every home, commercial building, and industrial setup. Their prevalence comes with the reliability of an RJ11 connector.
Have you ever wondered why the telephone cable doesn’t have a regular pin-type setup? Why does it have the standardised RJ11 connector? Let’s unravel these mysteries and what makes RJ11 such an essential tool for us to stay connected:
What is RJ11 In Telephone Cables?
RJ11 stands for Registered Jack 11. In a simple definition, it is the plug you find at the end of your telephone cable. At least all the standard telephone cables and many ethernet cables come with this RJ11 connection. It works with telephones and modems primarily. However, you can find many laptops and CPUs with the port available for it. Another point to note is that the modern ethernet cables use RJ45 connectors.
- An RJ11 has a square yet compact design with six metal contacts inside it. Usually, the square connector also has a lever for you to press to loosen it when you have to unplug it from somewhere.
- The RJ11 is prominently known for working effortlessly with other wires. You can easily pair more than one RJ11 connector together.
- If you’re looking for RJ11 connectors, the RS website provides them.
The 6P4C Technical Jargon
Often, RJ11 is also known as 6P4C, which signifies the 6 positions and 4 conductors it has. Primarily, it shows that RJ11 has 4 lanes of wires that provide proper and clear information. Moreover, it can ensure the best telephone network.
Where Are The RJ11 Connectors Used?
RJ11 connectors are used in the legacy devices and gadgets. A legacy device is an outdated piece of technology that is still in use in a wide range of operations. For example, a fax machine is an example of a legacy device.
However, in the technical spectrum, legacy devices usually don’t have modern connectivity options like HDMI, Type C, USB, and such. They rely on older and more secure connection options, like VGA instead of HDMI, Serial Ports instead of Type C or USB, and RJ11 instead of modern RJ45 ethernet cables.
Hence, you can find RJ11 being used in:
- Telephone connections, especially in a wide range of landlines. It is still a reliable option and doesn’t need any kind of upgrade for you to make calls from a landline.
- Many dial-up models utilise RJ11 ports. However, modern modems and broadband connections are inspired by RJ11.
- As mentioned earlier, many fax machines, printers, and scanners utilise RJ11 connectors.
Is RJ11 Still Relevant?
Undoubtedly, RJ45 is quickly overtaking the ethernet world for its remarkable connectivity and high-speed data transfers. It works great with net Cat5 to Cat8 Ethernet Cables. However, it still falls short in the world of conventional communication.
RJ11 thrives for its affordability and durability and its prominence over legacy communication devices. You can find it in landlines, fax machines, photocopiers, and other similar machines. Even in transport communication, RJ11 is the ace up the sleeve. Therefore, it is still a pivotal part of the overall tech world.
The Bottom Line
A time will come when RJ11 will become ancient technology. However, it is still years, even decades, from now. If you love using conventional connectivity options, RJ 11 is still a brilliant option.
Hopefully, you learned everything there was to know about RJ11. And yes, you can get them replaced by a tech expert if the wire is working fine. Let’s explore more interesting things like RJ11 together.
