Difference Between Rj10 and Rj22 (With Table)

Telecommunication was once widely used in homes and offices, but now only a tiny percentage of people use phones. Even though they provide Ethernet services, they require wire connectors or Registered Jacks, which come in various configurations and are commonly used in telecommunication exchange companies. Rj10, Rj25, Rj12, Rj22, Rj9, and so on are some of them.

Rj10 vs Rj22

The difference between Rj10 and Rj22 is that Rj10 is a smaller, square-shaped device made of plastic that exposes the connecting wires. Rj22, on the other hand, is a tiny, square-shaped device that permits sight of the connecting cables.

Rj10 is a registered jack with the 6P4C and 6P2C configurations. For telecommunication businesses, it is a widely used registered jack. Except for the United States, Rj10 may be utilized for single-line telephony in many nations. Copper pins serve as conductors, and a gold covering protects them from corrosion.

Rj22 has a 4P4C layout, which stands for 4 Positions and 4 Connectors. Rj22 is not a registered jack, although it is informally included. In telephone handsets, the Rj22 port is utilized. It can also hold four wires at once, but it’s only valid for a limited amount of time. Copper pins are used as conductors and are gold-plated to keep them from rusting.

What is Rj10?

Rj10 is a trademarked jack that was developed in the 1970s in the United States. These registered jacks aim to connect a voice or data equipment item to a long-distance carrier. It is the most often used registered jack. It is a connection used by telephone exchange providers to connect single-line live wires.

The gadget has a small and square-shaped physical appearance. It’s also available in two distinct configurations, the first of which is 6P4C and the second of which is 6P2C. After decoding these names, it is intended for six positions and four connections, six classes two bonds. The device with the 6P4C configuration can concurrently handle four wires, but the device with the 6P2C design can only run two wires at a time.

Copper wire pins are utilized as conductors in Rj10, and they are coated with gold to prevent corrosion. The benefit of using Rj10 is that it has a dual setup, and the device’s body is constructed of plastic, making it more robust and more straightforward to use. It also has the loophole of being unable to handle heavier transmissions.

What is Rj22?

Rj22 is a modulator, not a jack, that connects cables and wires of other electrical appliances in computer networking, telecommunications, and audio headsets.

The Rj22 device has a similar physical appearance to the Rj10 device, but it has different configurations and shapes. The Rj22 is a small square-shaped device that comes in a 4P4C design. It has four positions and four connections, according to the decoded meaning. The Rj22 device’s body is made of plastic and is rigid. It also allows for visual inspection of the connected wires.

Copper pins serve as the conductor in Rj22, and they are gold plated to prevent corrosion. These are primarily seen in phone handsets. The advantage of utilizing Rj22 is that its body is constructed of plastic, making it highly robust. The gadget has a pleasing appearance. This gadget can handle four cables at once. It does, however, have the restriction of just being used in telephone handsets.

Main Differences Between Rj10 and Rj22

  1. The Registered Jack 10 is available in two configurations: 6P4C (six positions four conductors) and 6P2C (six positions two-conductor) (6 Position 2 Conductor). Registered Jack 22, on the other hand, comes with 4P4C. (4 Position 4 Conductor).
  2. The Rj10 is a small, square-shaped gadget constructed of trans upparent plastic. Rj22, on the other hand, is relatively tiny and square-shaped.
  3. Because Rj10 has two configurations, 6P4C and 6P2C, the first can handle four wires, and the second can hold two, whereas Rj22 can carry four wires at once.
  4. Rj10 is a standard that is used in phone lines and modems. Rj22, on the other hand, is used to connect a telephone handset.
  5. Rj10 has the drawback of being unable to handle large transmissions, whilst Rj22 can only be used for a telephone handset.


Rj10 is a telephone interface that comes with two or four-wire connectors. The use of tapes for connecting wires was replaced by registered jacks thanks to a small device with a plastic body. It became the most widely used registered jack due to its ability to hold two or four wires for transmissions at the same time. Analogues of telephone connections have a bandwidth of up to 24Mbps.

Because it does not connect directly to the public network, Rj22 is not a registered jack and does not have a code. It also has a plastic body that allows you to see the connection wires. Only suitable for use as a telephone handset. It can hold two wires at once.

 A modular connection features a transparent plastic body with a tab that secures the plug and jack into place. They are referred to as “RJ” connections in the technology industry’s jargon. Although strictly incorrect, this is a frequently used name practice.
