RJ45 connectors are an integral part of wired networks, providing fast and reliable connections for users. RJ45 wire connectors are mainly used in ethernet networks to provide a stable link between computers, routers and switches. 4 Cabling has a range of RJ45 connectors and couplers available to suit a number of popular cable types that you may already use in your network. 

This RJ45 guide will answer common questions about the connectors’ technical specifications and usage cases. Read on to find out how you can use RJ45 connectors as part of your network cabling setup, and find out handy tips to reduce network latency in your connections.

An RJ45 connector is a small coupler used to join two Ethernet cables together. Both ends of an RJ45 coupler use female connectors, allowing you to join male ends of cables together.

RJ45 couplers are used to extend the length of ethernet cables without having to replace them with longer ones. RJ45 couplers are invaluable in situations where custom cable lengths are necessary, or where it is impractical to run entirely new cables.

RJ45 couplers can affect the speed of your network if the quality of the signal degrades. This usually happens when the connection is not secure or the coupler is of low quality. Ensuring that both the coupler and the connection conform to industry standards will help maintain the speed of the network and reduce latency.

Power over Ethernet (PoE) is a technology which allows Ethernet cables to transmit electrical power and data. PoE technology can deliver standalone power to devices such as security cameras, VoIP phone systems and wireless access points. Non-PoE capable devices cannot transmit data and require separate power sources to operate.

RJ45 connectors are a common type of eight-pin connection designed for ethernet networking. The connectors look similar to a telephone jack, but are slightly larger. RJ45 connectors can transmit data and electrical power through twisted pair cables.

In ethernet networking, RJ45 connectors are used to physically link network hardware together. Devices such as computers, routers and switches can be joined using RJ45 connectors to a local area network (LAN). 

While they are all designed for the same overall function and have a standardised size, RJ45 connections are available in many different variations to suit the different types of cables they may be attached to. Some RJ45 connectors are designed for Cat5e cables, while others suit Cat6 or Cat6a cable types. You should choose the correct RJ45 connector for the type of cable you will be using.

RJ45 connectors are generally not reusable after they have been crimped to a particular cable. Attempting to reuse an RJ45 connector may result in poor connections and decreased performance of the network.

RJ45 connectors are suitable for use with the following twisted pair cables:

• Cat5
• Cat5E
• Cat6
• Cat6A

RJ45 connectors should be cleaned regularly using a dry, lint-free cloth to help maintain a good connection and reduce latency in your network. Wipe the metal contacts gently to remove any built up dirt or dust. You can use a small amount of isopropyl alcohol on the cloth if desired, but be careful not to force any liquid inside the connector. Avoid any other type of abrasive cleaning liquid or substance that can damage the contacts in the connector.
