This type of cable is typically used for direct computer-to-computer connections when there is no router, hub, or switch available.Ĭables that terminated with RJ45 connectors on both ends called RJ45 Ethernet cables. Some networking applications require a crossover Ethernet cable, which has a T-568A connector on one end and a T-568B connector on the other.
RJ11 CONNECTOR PATCH
If both ends of the patch cords are wired on the basis of one standard, it is a straight-through connection.
With regard to the two standards, there are two different connectivity forms. The differences between T568A vs T568B in color conventions are shown in the figure below. The T-568B wiring scheme is considered to be the more commonly used one. These wiring layouts have their own color convention to follow for electrical compatibility. The two standards define how the RJ45 pinouts arrange the individual eight wires when linking the RJ45 connector to a cable. T568A vs T568B are the two common wiring schemes, which are used to terminate the twisted-pair cable onto the connector interface.
RJ11 CONNECTOR HOW TO
How to Identify RJ45 Interface Color Code? 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. You cannot plug in an RJ45 connector to an RJ11 slot but the opposite is possible.
RJ45 is typically used in Ethernets or connecting cable modems with Wi-Fi routers. RJ11 is mostly used for voice applications. RJ45 connectors can support 10Gbps over Ethernet. RJ45 is also sometimes used for VoIP phones in offices.Ĭheck the table below to get a clear understanding of RJ11 vs RJ45. Thus, RJ45 can be used for data-intensive applications like Ethernet and can support bandwidth up to 10Gbps. On the contrary, 8 contacts will allow greater bandwidth. 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.Īs abovementioned, with 2 or 4 of the 6 available connection points, the RJ11 plug supports limited-bandwidth applications including phone lines and ADSL connections. RJ45 vs RJ11, the major difference lies in the number of wires in their connectors. RJ11 has a 6P2C or 6P4C configuration and is used for wiring a single phone line. Four of the pins are used for sending and receiving data, and the other four are used for other technologies or power networking devices.īesides the RJ45 interface, some other connector types, like the RJ11 interface, for example, may confuse you in some cases. RJ45 cable plug is usually made of a plastic piece with eight pins on the port. RJ45 connector is an 8-position, 8-contact (8P8C) modular plug, and jack, applied for Ethernet-based local area networks (LAN). Physically speaking, the connectors that registered jacks use are mainly the modular connector and 50-pin miniature ribbon connector types. "45" is the number of the interface standard. "RJ" means "registered jack" - a standardized telecommunication network interface for connecting voice and data equipment to a service provided by a local exchange carrier or long-distance carrier. RJ45 interface is considered the most common twisted-pair connector for Ethernet cables and networks. What is RJ45? Are you confused about different RJ45 interface types? Keep reading to explore more. These RJ45 cables feature a small plastic plug on each end, and the plugs are inserted into RJ45 jacks of Ethernet devices. Ethernet cables with RJ45 connectors are also called RJ45 cables. RJ45 connectors are commonly seen with Ethernet network cables. And the cable run needs a connector termination, requiring a jack, normally an RJ45 jack, to plug into.
Only the right connection to an RJ45 interface or RJ45 connector will realize the transmission. Cables transmit information along the length.
