Difference Between Rj11 and Rj45
Table of Contents
A standardized network interface used as an interface in telecommunication networks to a local exchange carrier service or a long-distance service carrier is called a registered jack. The commonly registered jack cables used with UTP cables are Rj11 and Rj45.
These registered jacks establish connections for telecommunication lines. the registered jacks originated in the 1970 s with the introduction of the Universal Service Ordering Code (USOC) scheme of the Bell System.
Rj11 vs Rj45
The main difference between Rj11 and Rj45 is that the former is predominantly used as cable connectors in telephones, modems, and ADSL lines. The latter, on the other hand, is used as connectors in computer applications and for connecting the network elements. They also differ in the number of slots. Rj11 has only four slots, whereas Rj45 almost double the number of slots.Rj45, with its eight slots, is larger concerning Rj11.
Rj11 is the most commonly used registered jack in the field of telecommunications. This telephone interface is made up of twisted pair of wire in addition to a modular jack. It is made up of unshielded twisted pairs (UTP). The most common and popular function of Rj11 is to plug in the telephone. It is usually designed to hold six wires for a maximum of three telecommunication lines.
Rj45 is widely used in ethernet connections and networks. It consists of eight wires or slots that are in different colors. Registered Jack-45 or RJ-45 is most commonly used in industry today for high-speed networks’ wiring and connections.
The RJ-45 connector is also commonly used in flood-wired environments. These cables are wired in two different ways or versions, T-568A and T-568B. Initially, these were used as connectors in telephone networks and later implemented in high-speed applications. It is made up of unshielded twisted pairs (UTP). These are also known as data jacks.
Comparison Table Between Rj11 and Rj45
| Parameters of comparison | Rj11 | Rj45 |
| Connectors | Being the most widely used registered jack, it consists of four slots or connectors and six positions. | It consists of eight slots or connectors with equally eight positions. |
| Bandwidth | It supports a bandwidth of around 24 Mbps. | RJ45 supports up to 10Gbps speed over Ethernet applications. |
| Size | It is smaller in size concerning Rj45. Due to its square-shaped nature, it is compact. | When compared with Rj11, it is bigger and much wider with more slots. Its rectangular-shaped nature makes it larger and bulky. |
Applications | It is used in telecommunication and telephone applications to connect the internet through modems. | It is widely used with ethernet applications and networks. It is used in LAN and ADSL applications. It also finds its use in automation industries. |
| Compatibility with the other model | Rj45 cannot be inserted in the Rj11s port. | Rj11 cannot be inserted into Rj45’s port. |
What is Rj11?

What is Rj45?
Rj45 is widely used in ethernet connections and networks. It consists of eight wires or slots that are in different colors. They are also known as data jacks. The Rj45 comprises eight slots or connectors having equally eight positions. The rectangular shape makes it more enormous and bulky. These cables tend to be wired in two different ways or versions, T-568A and T-568B.

Main Differences Between Rj11 and Rj45
Conclusion
The registered jacks are push-in and click types of connectors. The RJ (registered jack) standard was initially conceived and adopted by the telecommunications industry, with the United States FCC (Federal Communications Commission) designated as the regulating agency.
These twisted pair of wire connectors are used in telecommunications, ethernet connections, and modems. Rj45 and Rj11 are made up of unshielded twisted pairs of wires (UTP). These are standardized network connectors constructed of jack deconstruction and wiring networks.
They carry information and communicate over long-distance carriers and local exchange carriers. Of the defined connectors, the RJ standard primarily uses the 50 pin miniature ribbon and modular connector types depending on the specific RJ type that is defined.
