It is not always possible to determine the exact length of the Ethernet cable you will need for your network. This is why you should use a cable that is a foot or two longer than the desired length.

However, if the cable doesn’t reach where you want it to, there are ways to extend it. This will help you to run the Ethernet cable as long as you need to reach the end device.

How To Extend An Ethernet Cable

In this guide, we will discuss the different ways to extend an Ethernet cable. If you are bothered by the length of your Ethernet cable, you should give this post a read.

Best 4 Methods To Extend An Ethernet Cable

There are multiple ways to extend your Ethernet cable. The ones we are going to explain will help you to expand your Ethernet network without compromising the reliability and speed of the connection. Ethernet cables can be stretched up to 100 meters maximum. But with these methods, you can join multiple cables easily.

1. RJ45 Inline Coupler

RJ45 inline couplers are widely used in LAN networks. However, it can be used to expand the length of your Ethernet cable. All you have to do is connect two Ethernet cables. This method is ideal for extending the length of Cat6 cables.

RJ45 Inline Coupler

An RJ45 inline coupler looks like a keystone jack. While one end of the cable is plugged into the coupler, the other end is inserted into the device. This is probably the easiest way to increase the length of your Ethernet cable.

Many users opt for RJ45 inline couplers because they are user-friendly. It doesn’t require you to be a tech expert to use these tools. Also, couplers are cheap and easily available. With the help of RJ45 inline couplers, you can extend your cable without compromising the fast internet speed.

2. Ethernet Extender

Another effective way to increase the length of your cable is to use an Ethernet extender device. It is based on DSL technology that enables it to transfer data. It offers speeds of 50 Mbps over 300 meters and 10 Mbps at 1450 meters.

Ethernet Extender

Using an Ethernet extender has its benefits. First of all, it is a durable device, and second, it is affordable. There exist different types of Ethernet extenders that will help you to achieve the desired cable length.

The LRP-101-Ukit uses a telephone cable or UTP cable to extend Ethernet links. Using 4-pair UTB cabling will allow you to increase the length up to 500 meters. To extend the length further, you can use VX-VEB160G4. It can stretch the Ethernet links up to 2.5km.

The UTP Ethernet extender converts Ethernet to DSL and then reverses the signals back to the internet. There also exists Ethernet switches that serve as a bridge between the router and the computer. Some switches allow you to hook multiple devices to a single port.

3. Network switch

You can also use a network switch to expand your Ethernet network. It allows you to add extra Ethernet connections to your home network. Since you cannot get an Ethernet cable longer than 100 meters, you can use a network switch to expand its reach.

NETGEAR 5-Port Gigabit Ethernet Plus Switch

Network switches are great for Cat6 cables. It can easily receive and send data to the destination device. This is done by switching the packets.

Having extra Ethernet connections is great, especially if you have a large number of users. With the help of a reliable network switch, you can create two or more connections. All you need to do is connect the Ethernet cable to a switch. This way you can run multiple cables to the end device.

4. Fiber Media Converters

Fiber is any day better than copper as it supports longer distances. Fiber media converters are generally used in pairs. It extends the Ethernet cable by converting copper to fiber and then reverting to copper. It can also be used with fiber switches.

The good thing about fiber is that it transmits data by refracting light. This allows for better signal integrity than copper. The most popular types of fibers are ST, LC, MU, SC, and FC. Fiber is also immune to electromagnetic interference, ground loops, spikes, and surges. This makes it an ideal choice for industrial settings.

You will find different types of media converters including micro media converters, standard media converters, and industrial media converters. Each of these media converters is designed to meet a diverse range of industrial and commercial applications.

How Far Can you Extend an Ethernet Cable?

You should get a longer Ethernet cable, so you don’t need to make additional connections. But most Ethernet cables are only 100 meters long. There is hardly any brand that offers Ethernet cables longer than that.

Extending the length of your Ethernet cable beyond 100 meters can result in signal problems such as packet loss or disconnections.

Ethernet connection is classified into different categories like Cat7, Cat6, Cat5, and so on. The data transmission speed can range between 10 and 1000 Mbps. There also exist 10g cables that are ideal for commercial use.

Now let’s take a look at the maximum distance of the different Ethernet cables.

Ethernet Cable TypeTransmission speed & Maximum Length
Cat8It offers an amazing speed of 40 Gbps and can be extended up to 30 meters.
Cat7This type of Ethernet cable has a transmission speed of 1000 Mbps. It can be extended up to 100 meters.
Cat6aEven Cat6a can be extended up to 100 meters and has a transmission speed of 1000 Mbps.
Cat6The transmission speed within 37-55 meters is 1000 Mbps.
Cat5eThis type of cable can be stretched up to 100 meters. It has a transmission speed of 1 Gbps.

Final Thoughts

By now you should know the different ways to extend an Ethernet cable. The whole point of increasing the length of the cable is to make it reach the end device. Depending on your requirement, you can choose a suitable method to extend your cable. Some methods like an Ethernet extender can help you expand the reach of your cable up to 2.5km.
