Why rj 45

What is RJ45? Are you confused about different RJ45 interface types? Keep reading to explore more. RJ45 interface is considered the most common twisted-pair connector for Ethernet cables and networks. Physically speaking, the connectors that registered jacks use are mainly the modular connector and pin miniature ribbon connector types.

RJ45 cable plug is usually made of a plastic piece with eight pins on the port. Four of the pins are used for sending and receiving data, and the other four are used for other technologies or power networking devices. Besides the RJ45 interface, some other connector types, like the RJ11 interface, for example, may confuse you in some cases.

RJ45 adopts an 8P8C configuration. RJ45 vs RJ11, the major difference lies in the number of wires in their connectors. Take a closer look, you will find that RJ45 has 8 wires inside while Rj11 has 4 wires, resulting in RJ45's bigger size than that of RJ11's. As abovementioned, with 2 or 4 of the 6 available connection points, the RJ11 plug supports limited-bandwidth applications including phone lines and ADSL connections.

On the contrary, 8 contacts will allow greater bandwidth. Thus, RJ45 can be used for data-intensive applications like Ethernet and can support bandwidth up to 10Gbps. RJ45 is also sometimes used for VoIP phones in offices. Check the table below to get a clear understanding of RJ11 vs RJ You cannot plug in an RJ45 connector to an RJ11 slot but the opposite is possible.

Although the smaller size of RJ11 makes it easier to be plugged into the RJ45 slot, it is not recommended to do that since this may damage the device that adopts the RJ45 slot. News Blog Social Media.
