How to Extend Ethernet Cable?


Many office and home networks depend on network cables for stable data transmission. But when it comes to wired Ethernet installation, there is a problem - the Ethernet cable cannot always reach where you want to. Some novices choose to replace Ethernet cables with WiFi for convenience, but nothing can beat the stability and reliability of Ethernet cables, especially for those who often play computer games.

Can you extend the Ethernet cable? Will it affect the performance of data transmission? How long can you extend your Ethernet cable? What are the solutions to Ethernet cable extension? This blog will tell you everything about how to extend an Ethernet cable.

Ethernet Cable Max Length

Before extending your Ethernet cable, you should know more about Ethernet cabling and the maximum length of Ethernet cables. It is recommended that you use the longer Lan cable so that it can reach your desired places, but the maximum length of the twisted pair cable is 328 feet or 100 meters. Once the network cable runs beyond 100 meters, it will cause signal loss and affect the speed of data transmission.

Currently, the most common Ethernet categories are Cat5e, Cat6, Cat6a, Cat7, and Cat8, the speed of which ranges from 1000 Mbps to 40 Gbps. Here is a list of performance and the maximum length of different Ethernet categories.

Top 3 Ways to Extend Your Ethernet Cable

Ethernet connection is one of the most common cabling forms in LAN networks. You may often find that the new Ethernet cable cannot reach the desired devices, but there are some things that you can do. One thing you can do is to check whether you can buy a new cable to replace it, but it requires time and energy to re-run the cable. There are also other methods to extend your Ethernet cable and you can choose one according to your own need.

RJ45 Coupler

RJ45 coupler, also named Ethernet coupler, is a simple way to extend your Ethernet cable. It features male connectors on both sides, designed to connect RJ45 plugs. RJ45 couplers can help connect two Ethernet cables without any signal loss. The great thing about RJ45 couplers is that they are cost-effective and easy to use. In addition, this small thing won’t take up too much space, so it can also be used in the corner. This affordable product is very great for home and office networks.

RJ45 couplers can be divided into several types: inline, waterproof RJ45 couplers, and keystone couplers. In general, inline couplers and keystone couplers are recommended for indoor use, while waterproof RJ45 couplers are more suitable for outdoor use.

It is recommended that you use one RJ45 coupler to connect the Ethernet cable. Never use more than 3 couplers or it may affect the data signal. Remember that RJ45 couplers cannot extend an Ethernet cable over 100 meters (328 feet).

Network Switch

A network switch is a device that can receive and transmit data to your end devices, so it can provide additional Ethernet connections. The network switch is very suitable for large office that has many users. It helps you easily extend the Ethernet cable without affecting performance. If you have a short Ethernet cable, you can connect it to the network switch and run other two or three cables to your end devices.

Besides, a network switch is also a good option to break the 328-feet limit of Ethernet cable. Unlike RJ45 couplers, it can cover a distance of fewer than 200 meters without any signal loss.

Ethernet Extension Connector

An Ethernet extension connector is a special type of RJ45 connector or RJ45 coupler. It is a combination of extension, connection, relocation, and repair of two Ethernet cables. Though it can be seldom seen on the market, an Ethernet extension connector is very powerful. For example, if you have two short Ethernet cables in your hands and want to elongate the cable, you just need to connect them with this special connector.

In addition, this Ethernet extension adapter can be installed without the use of a crimping tool, which is very suitable for emergent situations. It is widely used in homes, offices, server rooms, and many other cabling scenarios.

Final Thoughts

There are many ways that can help you extend your Ethernet cable. And you can choose the most suitable method according to your specific need. We hope this blog can make the process easier for you.

Greater extension distance may require a more complex and expensive choice. A network switch and other Ethernet extenders can be a better option if you want to make an Ethernet connection beyond the 100-meter limit.


How long can I extend my Ethernet cable?

In general, the maximum length of twisted pair cables is 100 meters (328 feet). If you run the Ethernet cable beyond this limit, it might cause signal loss. But you can use a network switch or other Ethernet extenders to break this limit.

Will a long Ethernet cable affect performance?

In most cases, it does not affect the data transmission speed within 328 feet (100 meters).
