Difference Between RJ11 and RJ25 (With Table)

A registered jack (RJ) is a generic telecommunications network interface that connects voice and data equipment to a local exchange or long-distance carrier service. Registered jackets are then designated primarily by RJ text, followed by two digits expressing the form.
Both crimp gold pin connectors used in telecoms, networking, and even low voltage illumination applications are RJ11 and RJ25. The disparity depends on the number of places on the connector and the real number of contacts. The connector is bigger as there are more locations. The norm only specifies a connector’s cable pattern, not geometry or sex.

The name “Jack,” even though the standard does not distinguish the sex of the connector, applies to the female connector. These connectors are often called “modular connectors”, and they have made the phone network more modular in the early days. For the wiring of telecommunications networks, the RJ specification is mostly specified. The RJ-standard cable patterned connectors are referred to as RJ connectors and can be used in men and women.

RJ11 vs RJ25

The difference between Rj25 and Rj11 is that they are used mostly in the telephone industries. They have many similarities, but they are distinguished by their characteristics. There is already a vast range of connectors on the market and their features are distinct. Some are suitable for telephone, telephone, and other computer networking purposes. In telephone links, most of these are Rj25 and Rj11. They are quite different, with the Rj11, which is very slim, larger than the Rj25. Both are made of plastic, though, which allows you to see the ties inside.

The Rj11 is a square and lightweight unit with a diameter of 9,66mm. It’s made of solid plastic that is made of hard and durable plastic. It is visually clear, which makes it possible to see the attached wires. The pattern for the Rj11 must be configured. A 6P2C pattern is the first setup. This means that the connector has six locations and two attachment points, enabling it to handle two copper wires simultaneously.

The second setting is the pattern 6P4C. The connector has 6 locations and 4 points of attachment. This allows it to accommodate up to 4 wires per go, two more than the 6P2C, which gives it a better transfer capacity.

The Rj25 is significantly smaller than the Rj11, but it’s powerful too. It is lightweight and also translucent in square form, giving it a fascinating appearance. This jack is set to 6P6C. It has 6 locations and 6 attachment points, which ensures 6 copper wires can be handled at a time.

O que é RJ11?

An RJ11 port is available to many machines. It’s normally on the computer’s side on notebooks. It is on the back, or somewhere on the front near the DVD tray on desktop computers. This socket’s key function is to communicate with modems. Currently, the RJ11 jack is a little wider, just next to a socket that looks the same. This network socket RJ45 connects to a DSL internet connection, and it is now the most used adapter. Both sockets are connected to a network adapter that converts machine data into a network-friendly format. At the base of the RJ11 port are 6 channels, each with a metal stripe of copper.

This strip is a contact that forms a bond in the plug tough to the sockets when the matching metal strips. To make calls, the telephone line may be connected to the RJ11 port on a device. This setup requires the network adapter-compatible call control tools. Typically such applications can accept faxes and archive them as data files. It also generally allows you to build an extension and voice mail structure for your switchboard. Calling can be sent to an automatic response or held in a holding position, whether the caller is listening to the computer’s music or message.

What is RJ25?

This unit is much smaller than the Rj11, but not to be underestimated. The material is often used to display the ties using translucent plastic. Contrary to Rj11, this unit has a 6P6C configuration, enabling it to accommodate up to 6 cables simultaneously.

It has copper pins that serve as electromagnetic pulse conductors. They are covered with gold to avoid rusting. This computer can be connected simultaneously to three computers. Pros of rj25 are- It can accommodate six wires at a time. It is powerful and long-lasting. It has gold-coated copper pins to prevent rusting. Three devices can be connected simultaneously.

The prototype machine has two boxes – one with a microcontroller and power control and the second with an IR cable attached to it. Electricity reaches the receptacle IEC 320 on the back, and a power outlet of 5-15R can be connected to the power supply of the entertainment center. A little part of A.C. Input current is translated into 5 VDC for use of components by switching mode. The power supply and the remainder pass through a switched relay and a current sensor. Control outlet of the machine. A remote signal of around 15 meters can be received by the IR sensor.

Main Differences RJ11 Between and RJ25

  1. RJ11 is a cable adapter for internet, ADSL and modem cable applications, etc., whereas RJ25 jackets for telephone systems are used in networking.
  2. RJ11 is a connector with four slots, whereas RJ25’s a six-slot plug.
  3. RJ11 has 6 positions of 4 wires, whereas RJ25 has 6 cable positions.
  4. RJ11 is 4P4C and 6P4C, whereas RJ25 is the norm for 6P6C cabling. There are also 6 wires in the conduit, which fill all the available slots.
  5. RJ11 is smaller than RJ25 visually, whereas rj25 is Shoot bigger than RJ11 Physically.
  6. Rj11 is Square form compact, whereas rj25 is Compact. More round, lighter.


The RJ11 is the licensed telecommunications jack that is most commonly used. This is a modular telephone connector wired with two connections from the middle of six positions open. In several countries other than the USA, this setup is often used for single telephones. You may also use a 6P4C adapter to power telephone lamps with an extra wire pair. RJ14 is RJ11-like, but it has two lines and three lines for RJ25.

RJ61, however, uses an 8P8C connector, is a similar registered four-line jack. For their specific devices, the Rj11 and Rj25 are both efficient connectors. It has two setup patterns. The Rj11 is unique because it has three devices at once. The Rj25 is excellent to manage three devices. The Rj25 can accommodate six wires on one go and even connect three devices simultaneously. This is why it is a better producer than the Rj11.
