4 Reasons to Rely on RJ45 Connectors for Ethernet Networking

The RJ45 connector is a small but powerful device at the core of Ethernet networking, which has become an essential part of our lives – from streaming movies to video conferencing. It's what enables us to access the digital world.

This article will explore this vital component and unravel the mystery behind its role in Ethernet networking. Whether you're a tech enthusiast or a curious beginner, read on to discover how it keeps us connected and how to find the right RJ45 connector for your needs.

What are RJ45 Connectors?

RJ45 connectors are small, modular plugs used to interconnect devices in Ethernet networks. The name is derived from the 8P8C design of these connectors, which has become a standard for connecting computers and other peripherals such as routers and switches.

An RJ45 connector consists of a plastic body with metal contacts on either side that connect two electrical circuits; its PoE (Power over Ethernet) version can even power up devices such as IP cameras, VoIP phones, and access points.

4 Reasons to Use RJ45 for Ethernet Networking

  1. Cost-effectiveness: RJ45 connectors are relatively inexpensive and easy to install such as an EZ-RJ45 Cat5e feed-through connector for solid & standard cables.
  2. Pinout verification: Before you crimp an RJ45 connector, verify your pinout to reduce any possible damages.
  3. High-speed data communication: RJ45 connectors transfer data at lightning speed, depending on your network cable. The Cat8 RJ45 Field Termination Plug, a shielded RJ45 plug supporting PoE++ applications, can comfortably handle network connections with speeds up to 10, 25, or even 40 Gbps.
  4. Universal acceptance: The 8P8C design of the RJ45 connector is widely accepted by many networking devices across different vendors. This makes connecting your computer or peripheral to any Ethernet network easier, regardless of where they come from.

RJ45 vs RJ11: How are They Different?

When talking about RJ45 connectors, it is important to consider their counterpart – the RJ11 connector. Even though they may appear similar, these two types have distinct applications.

The RJ45 connector has eight pins and eight wires and is 6mm by 11mm in size – primarily used to enable high–speed data transfer between computers, Wi–Fi routers, fiber modems, and NBN boxes.

In contrast, the RJ11 connector has four wires and four pins; it's smaller than its sibling at 6mm by 9.5mm and is mainly used for ADSL/VDSL connections or telephone networks. Check out our RJ11 to RJ45 wiring diagram to see the difference. RJ12 connectors are the newer version of RJ11.

Common Classifications of RJ45 Connectors

RJ45 connectors are classified based on the type of wiring used. The most common types of RJ45 connectors include Cat5e, Cat6, and Cat7.

Cat5e is the go–to Ethernet cable, utilizing an RJ45 Cat5e connector and perfect for home networks where data transmission speeds rarely exceed 100 Mbps.

For more demanding applications such as data centers and cloud computing networks, Cat6, Cat7 and Cat8 standards are used.

RJ45 Connector Accessories

RJ45 facilitates a wide selection of accessories, making Ethernet networking more convenient and productive. These include crimping tools, patch panels, couplers, adapters, and cable tester kits.

For example, the RJ45 Field Termination Jack is a breakout board with a metal housing that supports screw–down installation. You will also find various couplers with durable waterproof dust caps, such as the 740C Waterproof RJ45 Splice Coupler for outdoor networking applications. We also have a Cat5e Ethernet cable splice in stock and ready to ship.
