Can You Split An Ethernet Cable? Connecting To Multiple Devices

Can you split an Ethernet cable? In networking, Ethernet cables transmit data signals across devices, ensuring seamless connectivity. However, sometimes, they cannot supply wired internet connections to everyone in the office or all devices.

As much as everyone wants an Ethernet link in their home or office, there are not enough for everyone. It will always be a rush as to who bets the Ethernet link the first. 

Understanding the possibility of Ethernet splitting helps optimize network configuration and address connectivity. 

People want the internet these days and need it fast and reliable. What could be better than a high-speed Ethernet connection? Join us as we explore Ethernet splitting in network engineering and determine if it’s possible.

Can You Split An Ethernet Cable

Yes, of course! You can split an Ethernet cable with a splitter or a network switch. A splitter is a small device that can divide an Ethernet cable into two separate links. 

This is helpful if you connect a wired Ethernet device far from the router or modem with a single line.

Ethernet splitting is common and accessible in local area networks these days. Most networks have ethernet splitters installed, which lets more people join the network. 

Ethernet Splitters Explained

They are also known as network splitters and LAN splitters. They use a single Ethernet cable and distribute data to several Ethernet cables. 

This lets you connect several devices to a single Ethernet port, like a router or switch. Ethernet splitters can be grouped into; 

  1. Passive Ethernet Splitters: They are the most common as they work by splitting the Ethernet signal into several signals that go out. They are pretty simple to do and don’t need power.
  2. Active Ethernet Splitters: They are more modern and work by amplifying the signal from the main Ethernet cable. This makes the link stronger and more stable so that many devices can use it.
  3. Power over Ethernet (PoE) Splitters: POE splitters provide power to connected devices differently.

Here’s how you can split an ethernet cable; 

a. Use an Ethernet Splitter Cable

Using an ethernet splitter cable is one of the easiest and preferred methods. Most Ethernet splitters have two Ethernet ports on the other side and one Ethernet port on the other side. The Ethernet splitter lets two devices in different places connect to the router.

You will need two of them to split your ethernet cable. One combines two Ethernet signals from the same device, while the other splits them into two lines so that two devices can connect.

You may connect two IP cameras if the Ethernet splitter works with a PoE switch. Some people might wonder if they can only use one Ethernet splitter. Remember that a single splitter can only work as an extender with one working port.’

Will It Reduce The Speeds?

Whether the ethernet splitter will reduce the speeds depends on your network. The Ethernet splitter works with Mbps speeds so that it won’t slow down a 100 Mbps network. 

But if you connect it to a server that can handle a 1 Gbps network, the splitter will slow your internet speeds, affecting your browsing.

The Ethernet splitter is still built on the old standard, it carries with it some limitations. In this case, each port can only connect to two devices in the same room and has a top speed of 100 Mbps.

All in all, the splitters are standard and don’t need any configuration or complex setups. These Ethernet splitters also help protect cables and wall outlets while providing a robust and reliable Internet link. They are also less expensive than other networking equipment. 

b. Using the Router as an Ethernet Splitter

Using another router as a splitter is an attempt to improve the internet’s bandwidth and speed. Moreso, one router acts like a failsafe in case one router fails. Using routers also allows users to send and download files at a faster rate seamlessly.

Routers create a local area network allowing a number of its devices to communicate over specified areas. 

When linked to a cable modem, a router grants access to all LAN users. Wireless routers are practical and typically straightforward to configure. 

The major drawback is that the network performance drops, and there’s a decrease in speeds. Businesses or users needing quality internet require a wired connection between the routers.

Benefits of Using Routers To Split Your Ethernet Cable

Linking several routers through ethernet increases the network’s performance. This ensures every computer/ device is connected to the internet by cable, enjoying incredible download speeds. 

It also guarantees stable connections with less latency and enhanced online presence when browsing the web.

In addition to enhancing network security, connecting multiple routers safeguards devices prone to network attacks, such as computers and phones.

Configuring your router can be extremely useful if you have a large home filled with Wi-Fi and smart devices. You’ll need to control downtime that includes lost connections and achieve improved coverage across multiple areas of your residence. 

Splitting your ethernet cables this way leaves you with two routers distributing your internet connection. The two or more routers guarantee great coverage and improved speeds in the house.

Splitting the ethernet cable using routers allows you to create multiple networks needing access authorization. This gives you control over who has access to some parts of the network.

Here’s how you can use a router or modem as an Ethernet splitter;

  • Find the modem or router and the Ethernet wire you want to split.
  • Connect the Ethernet cable to the “WAN” or “Internet” port on the modem or router.
  • Use Ethernet cables to connect the devices that are on the network to the router or modem.
  • You have now linked the devices to the network.

Remember that a router or modem working as an Ethernet splitter lets devices wirelessly join the network. You can use this to connect mobile devices such as phones or devices that lack the Ethernet port.

c. Use an Ethernet Cable Sharing Kit

It is a kit with a central unit and two or more devices sharing the same internet network and can be put in different rooms of the house or office.

Simply put, it unifies the two Ethernet cables originating from the router. It then divides the single Ethernet cable into two cables in a separate area. Go for a network switch if the number of devices to connect is three or more.

You must have the main internet supply through a modem or router. Then, use the Ethernet cables with the kit to connect the other units to the networked devices. The process sounds a little technical, but the results are worth it as it ensures no speed latency.

Alternatives to Splitting an Ethernet Cable

Here are other ways to connect multiple devices to the internet simultaneously without splitting the Ethernet cable. 

  1. i) Ethernet Switch

An Ethernet switch increases the number of available Ethernet ports for your devices. You can connect several devices to the switch using extra Ethernet cords or jacks when you connect the switch to the internet router using a single Ethernet connection. 

This lets each device have its dedicated link, ensuring faster and more reliable speeds.

  1. ii) Wireless Connectivity

Another way to let multiple devices share an internet link is with a wireless router or access point. These gadgets create a wireless network that connects to other devices without cables.

Several devices can connect to the internet simultaneously through a wireless connection, which is flexible and helpful.

iii) Ethernet Splitter vs Switch

An Ethernet splitter allows you to split an Ethernet cable into several connections. A switch, on the other hand, will enable you to add more ports to your network. It uses packet-switching technology to connect several devices and forward data to the devices.

If you want to connect numerous devices to a single port, use the Ethernet splitter. However, go for the Ethernet switch to expand your network’s interface capacity to connect additional devices.

Difficulties of Splitting an Ethernet Cable

Splitting an ethernet cable is not the advisable way to go for your networking system. 

Ethernet cables are designed for connecting two devices through P2P connections. If you try to split the cable, you might lose the signal, get reduced performance, or have connection problems.

a. Loss of Signal & Poor Performance

Ethernet links several twisted pairs of wires to send data. When you split the cable, the pairs lose their exact configuration, which causes signal interference or loss.

Sharing Ethernet cables slows the link, so sharing adapters is not recommended. This will reduce productivity in workspaces, especially if you’re working on heavy projects such as app development

b. Connectivity Issues

If you split an Ethernet wire, you might have trouble connecting. Routers, switches, and other Ethernet devices communicate properly through direct cable links.

Splitting the cable breaks up the signals, making it hard for the devices to recognize each other and establish consistent connections.


Can you split an Ethernet cable? Ethernet splitters come in different forms, including passive and active POE splitters. This guarantees increased flexibility of your network. Go for the option to guarantee the number of ports you need for your office equipment. 

Your chosen method will need quality network configurations and cables to keep things running smoothly and reduce downtime. In general, choose one with a few additional ports than you require, just in case.

When setting up any networking system, it’s best to adhere to the manufacturer’s instructions for a seamless connection.
