RJ stands for Registered jack that is a female type connector used as system cables, wiring, and for manufacturing jacks. The main purpose of a registered jack is to connect a variety of telecom devices and data tools with services provided by network servers and communication service providers.
There are different types of registered jacks used for different purposes, for example, RJ-45, RJ-11, and RJ-14, etc. Where RJ-14 is used for connecting two telephone lines or four wired devices, whereas RJ-45 comes with 8 pins used for computer network interconnections and exclusive telephone circuits. RJ-14 is similar to RJ-11 except for the pin configuration because, in RJ-11, only 2 pins are used as conductors.
RJ14 vs RJ45
The difference between RJ-14 and RJ-45 is that RJ-14 comes with 6 positions where 4 positions are placed, and those 4 positions are 2,3,4 and 5. It uses a 6P4C modulator connector type. And RJ-45 is majorly used for ethernet connections. It has 8 positions with all 8 pins used.
RJ-14 has a 6 position connector where 4 pins are used either for 4 wire devices or two phone line connections. It uses a 6P4C connector type and a 6P2C modulator connector with four conductors. RJ-14 is similar to RJ-11 except for the pin configuration because, in RJ-11, only 2 pins are used as conductors.
RJ-45 is a registered jack that is used in ethernet connections or computer networking connections. It comes with 8 position connectors where all 8 pins are placed or used as conductors. It is broader than a telephone jack. Wiring can be done in two different types of termination standards; the first is T568A, and another is T568B.
Comparison Table Between RJ14 and RJ45
|Parameters of Comparison||RJ14||RJ45|
|Pins and positions||It has 6 positions with 4 pins placed or used as conductors.||It has 8 positions with 8 pins placed or used as conductors.|
|Connector type||RJ-14 has a 6P4C connector type and a 6P2C modulator jack.||RJ-45 has an 8P8C connector type that is 8-position, 8-contact.|
|Number of wires used||Four wire connections can be made.||Eight wires connection can be made.|
|Positions of wires||Pin 2 for negative wiring and pin 5 for positive.||4 pins moved to the positive wire and 4 pins for the negative wire.|
|Usage||It is used in two-line communication or for connecting two telecom lines.||It is used in Ethernet networking and computer network connections.|
What is RJ14?
RJ-14 comes with 6 position connector where 4 pins are used either for 4 wire devices or for two phone line connections. It is mainly used for two-line communication. It has a 6P4C connector type and a 6P2C modulator jack. RJ-14 can also be used when you have multiple lines conducting to a single connection.
RJ-14 has four wires with a position as pin 2 for negative wire and pin 5 for positive wire. RJ-14 is similar to RJ-11 except for the pin configuration because, in RJ-11, only 2 pins are used as conductors. In RJ-14 wiring, all the connectors can be used except 6P2C as it has insufficient important junction points.
RJ-14 is only used for 4 wire devices that are commonly used in private telecommunication lines circuit in the United States. And are also used in modems that are manufactured in the United States.

What is RJ45?
RJ-45 is a registered jack that is used in ethernet connections or computer network connections. It comes with 8 position connectors where all 8 pins are used as conductors. It is broader than a telephone jack. Where 4 pins are for the positive terminal and 4 pins for the negative terminal.
RJ-45 uses an 8P8C that is an 8-position, 8-contact connector type. Its connectors are a little bit bigger than RJ-11 connectors. Two different types of wiring methods are available in RJ-45. One is TB68A other is TB68B. It is used to connect 8 wires at a time, mostly used in ethernet cables.
RJ-45 is used to connect different types of devices related to computer networking, for example, switch, hub and PC, etc., to each other. And it is used in bigger connections because it has 8 wire connection facility.

Main Differences Between RJ14 and RJ45
- RJ-14 comes with 6 position connector, and RJ-45 comes with 8 position connector.
- In RJ-45, all the 8 pins are used as conductors for 8 wire connections, but in RJ-14, only 4 pins are used for 4 wire connections.
- RJ-14 has a 6P4C connector type and a 6P2C modulator jack. And RJ-45 has 8P8C that is 8 position, 8-contact connector type.
- RJ-45 is mainly used for ethernet or computer networking connections, and RJ-14 is used for two-line-based communications but can also be used when multiple connections are connected to a single endpoint connection.
- In RJ-14, positions of wires are like pin 2 for negative wiring and pin 5 for positive. While in RJ-45, 4 wires each for the negative terminal and positive terminal are used.
Registered jacks are connectors. They come in different types, each having different functions. RJ-14 is a type of registered jack that is used for connecting a two-line network, and it comes with a set of 6 connectors where 4 pins are used as conductors. It can also be used in a network where multiple connections are connected to one endpoint or node. RJ-45 is for long-range networks or connections which come with an 8-position, 8-connection connector type.
Both of the registered jack have different functions and different connection types. In RJ-45, 8 wires can be connected, and it is used for connecting devices like a switch, hub, and PC, etc., to each other like we all have connections in offices, schools, etc. But when it comes to connecting small networks like two-way communication ports or lines, we use RJ-14 which has 4 wires for connection purposes.
In RJ-14, positions of wires are like pin 2 for negative wiring and pin 5 for positive. While in RJ-45, 4 wires each for the negative terminal and positive terminal are used. RJ-14 is comparable to RJ-11, but their pin configuration is different.
