RJ 45 vs RJ11

T568 A or T568 B Wiring Schemes- What's the Difference? Based on TIA/EIA-568-B.1-2001, the T568A and T568B wiring schemes define the pinout, or order of connections, for wires in eight-pin modular connector plugs and jacks. The only difference between T568A and T568B is that pairs 2 and 3 (orange and green) are swapped.

Place all 8 wires into the center of the jack; from there, divert the wires into their correct slots, pressing them as far down into the termination slots as they will go. Excess wire length will be extending out of the sides of the jack. It's easiest to punch down wires if you do one side of the jack at a time.

Registered Jack is the meaning of the acronym RJ which is the acronym that cable connectors usually start with. Two of the most common jacks are the RJ45 and RJ11, each with their own specific purpose. The main difference between these two is in where they are actually used. RJ45 jacks are used in networking, where you connect computers or other network elements to each other. RJ11 is the cable connector that is being used in telephone sets.

Aside from the application, there are also differences that an individual can easily see and identify. The first of which is in the number of cables that are accommodated in each connector. If you look closely at both connectors, you would see that there are only four wires inside and RJ11 while there are eight wires inside an RJ45. As a consequence of having to accommodate more wires, RJ45 connectors are also a little bit bigger than RJ11s. It is then quite easy to deduce that you cannot plug-in an RJ45 connector to a RJ11 slot but the opposite is possible.

Although you can plug an RJ11 connector into an RJ45 slot, you should avoid doing that because you might damage the device that has the RJ45 slot, whether it is a switch or a network adapter. This is true when you use an RJ11 connector that is connected to your phone line. The reason behind this is the power that is being delivered by the telephone company into your handset that allows it to function even during a power outage. But with proper knowledge and training, some people have been able to use RJ45s all over their house instead of RJ11s.

A lot of people have begun to place RJ45 jacks on wall outlets inside their houses in order to reduce the number of visible wiring when using VoIP handsets that are rapidly gaining popularity right now. These mobile phones need to connect to your network instead of your telephone line. Usually VoIP handsets are found beside routers or computers, but having an RJ45 outlet gives VoIP phones the same amount of freedom as standard telephone sets when it comes to positioning.

Summary:
1.RJ45 is used with ethernet cables in computer networking while RJ11 is used in connecting telephone units
2.RJ45 contains more wires than RJ11
3.RJ45 is physically bigger than RJ11 to accommodate the extra wires

RJ11 vs RJ12

The registered jack standard has been around for some time for people to follow in wiring their telephone lines. It is abbreviated into RJ and is then followed by two digits that identify the specific standard. The RJ11 and RJ12 standards are quite closely related and in fact look identical to each other to the uninitiated. This is because they both use the same six slot connector. The only difference between these two is in how they are wired and the number of the wires that are being used.

RJ12 is a 6P6C wiring standard. This means that there are also 6 wires that are terminated in the connector, occupying all the available slots. RJ11 is a 6P4C wiring standard and only has four wires connected and the remaining two slots are no longer used. Because of this, you would need to pay close attention to the cables that you are utilizing as cable used four RJ11 might not be suitable for RJ12, even if they look identical.

Despite the differences, both wiring standards are used for the same purpose, telephone lines; commonly using the center pair. But there are also other applications that make use of the RJ12 standard. Keyed telephone systems and PBXs may take advantage of the additional two connectors. Because of this, RJ12 is not really very common and only the people who have experience working with large company’s telephone systems are familiar with RJ12 wiring. RJ11, on the other hand, is relatively very common because it is used in the majority of the phone units and wiring of some telephone companies. This has even developed into the connector itself being popularly referred to as RJ11.

There is really no individual decision whether to choose RJ11 or RJ12 in your connection as this is often dictated by the telephone company that you are subscribed to. With that said the additional two lines that are made available when using the RJ12 standard can become quite handy in a PBX system where you can add extra lines on your own.

Summary:
1. RJ11 and RJ12 wiring uses the same six slot connector
2. RJ11 and RJ12 only differs in the wiring
3. RJ12 utilizes all six slots while RJ11 only uses four of the six available slots
4. RJ11 and RJ12 are commonly used for telephone systems with RJ12 being used in different configurations
5. RJ11 is very common in today’s homes while RJ12 is quite uncommon except in some large companies
