Ethernet Splitter vs. Switch: What’s the Difference?

Did you know your choice of Ethernet switch or splitter can make a massive difference in the performance of your commercial network? Today, we’ll explore the differences between an Ethernet splitter vs. switch. We’ll also show you which one is best for maintaining or improving network performance.

Read on to discover more about the distinctions between a network switch vs. Ethernet splitter.

The Value of Ethernet Connectivity

Ethernet connectivity uses wires, unlike Wi-Fi. Ethernet network cabling runs from the router or modem to RJ45 ports on other endpoints, such as laptops and phones.

Your decision to use either twisted pair, optical fiber, Ethernet, or coaxial cables would vary based on the network’s protocol and size. However, with Ethernet cables, its benefits come from the reality that networks don’t have as many connectivity or wireless cybersecurity problems.

Benefits of Ethernet Networks

Ethernet is still the worldwide standard for linking multiple devices over a network for better communication, despite the need for hardwired cables. These cables have an exceedingly high speed and power connection.

Besides that, there are usually smaller latency, interference, and security risks than other protocols. Ethernet is the best way to send high-speed, private, and uninterrupted data.

Why Use a Switch or a Splitter?

Small industrial Ethernet networks typically work fine in any configuration for a few years. As you add more equipment and networks, you may want to expand it.

How do you do that? The best way is to use a switch or an Ethernet cord splitter.

These options have the same primary purpose—to help you grow your network. It’s just that they’ll get the job done differently, each one with its own set of drawbacks and benefits.

What Does an Ethernet Splitter Do?

It’s easiest to split up a network connection with an Ethernet splitter. The device turns one cable into a pair.

For instance, someone might use an Ethernet network for PLC communication. It would be easier to run a cable through the ceilings and walls if you used Ethernet splitters.

It’s best to use splitters to reduce the long cables you must run between rooms in a structure. This means you don’t have to run two Ethernet cables from one room to another.

It doesn’t, however, mean that you can link more devices. You’d need to use Ethernet splitters in sets to get the connection back together again for the pair of network devices that need it.

Benefits of Ethernet Splitters

Only 10 Mbit and 100 Mbit Ethernet need four wires, but most cables, like Cat 5e, have eight. Ethernet splitters make use of this point.

When using a splitter, you’d only use two wires and send data through two distinct ports. This means that the total bandwidth is 100 Mb/s.

Splitters are passive. They don’t need a power source like hubs and switches. Still, because Ethernet switches are easy to use, they’re also the most affordable way to split a connection.

Splitters Can’t Outperform Switches

Internet switches are more suitable for environments where there’s a lot of traffic from many different devices. They provide a faster network that doesn’t get slowed down by other devices.

Because they come in a vast range of configurations and features, this is the best way to add more Ethernet ports. These benefits are why Ethernet switches are the best way to split Ethernet.

Need-To-Know Facts About Ethernet Splitters

An Ethernet cord splitter doesn’t make your network bigger. It takes a single Ethernet connection and splits it into two separate connections. You’ll no longer need to use two Ethernet cables when you want to connect devices in two different rooms.

To connect two devices and move the data from one Ethernet cable to another, you can use a splitter. You’d cut the cable in half. Then, you can move the data to different rooms.

One of the best characteristics of an Ethernet splitter is that it doesn’t need electricity to work. It doesn’t have to be set up in a complicated way. It’s simple and easy to use.

When to Choose a Splitter

Ethernet splitter are suitable for people who just want a wired connection and don’t care about the speed or throughput of the connection. The device is cheap and straightforward to use, however, you still want the best Ethernet splitter you can buy.


It’s made of thick plastic and can connect to male or female parts. It lets two devices connect to each other at the same time.

When Not to Choose a Splitter

A splitter allows you to have two wired connections where you only had one before. Still, it does so at the cost of the strength of the signal. If you split up an Ethernet connection with a splitter, it will slow down a lot.

Both of your devices are, in a sense, taking up the same connection. So, in effect you are splitting the bandwidth it to less than half of what it was before.

What Does an Ethernet Switch Do?

An Ethernet switch is a high-speed device with many extra ports. It’s the best way to split an Ethernet connection because it can do so without causing a considerable drop in performance.

As long as you have network devices, you can use any of the switch’s other ports. This way, the switch can easily and quickly direct traffic.

You can quickly identify each client by its network address. Also, Ethernet switches come in different speeds and sizes, ranging from 5 to 52 ports.

Going Deeper Into Ethernet Switches

Switches break up the network into smaller, less crowded paths by switching packets. This is a way to send small parts of information across the network, making it faster and more efficient.

Devices get the bandwidth they need without dealing with other network traffic that might slow them down. Each connection to a device is a separate path that doesn’t slow down the whole network.

Full-duplex communication from an Ethernet switch means you can send and receive data simultaneously, which speeds up the whole network.

Ethernet Splitter vs. Switch: Which Is Better?

Because splitters have the previously mentioned flaws, a switch is usually a better way to split Ethernet. Splitters don’t work as well as switches. Devices connected with splitters only have a speed of 100 Mb/s.

Using this method, you can only connect a limited number of devices. If you use a switch, however, you can connect many devices.

How Ethernet Switches Work

You can connect many different things to the same router or modem port with an Ethernet switch.

Because a network switch has a lot of ports, you can connect devices by plugging in Ethernet network cables to the available docks. This makes it possible for devices on different networks to communicate with each other.

Network switches are more functional because they can control how much information or data moves across the network by sending a network packet to the right place. This makes them more intelligent.

It gives each device on the network a unique network address, making it easier and faster for data to move through the network. It also protects the network.

Can’t I Just Use an Ethernet Hub?

Imagine a small business network with only a handful of devices and only a few or more people who use them. In this case, using an Ethernet hub is fine.

Eventually, however, your network will grow. You’ll see a hub can’t keep up with the increased workload when it does. With this in mind, it’s a good idea to buy a more powerful Ethernet switch that costs a little more.

Planning for Growth

You may operate a small business network with a limited number of devices now. Still, you may have times when there are sudden surges in traffic. Then, you’ll most likely wish you had an Ethernet switch instead of a hub.

A hub could handle most of the traffic on a typical day. However, it isn’t the best option when many people work in the same place at once.

Need-To-Know Facts About Ethernet Switches

Of course, an Ethernet switch also has its downsides. For example, a power-hungry Ethernet switch needs plenty of electricity.

Still, many switches have several high-speed ports. You can use them to connect many things, from a computer or laptop to a printer, camera, or other data-hungry devices.

When you turn the device on, it connects everything. In this way, it’s a good tool for expanding your network without sacrificing speed or security.

These devices indeed have both good and bad things about them, just like they each have unique needs and uses for networking. However, it’s best to go with a switch instead of an Ethernet or hub if you eventually want or need to grow your network.

When to Choose a Switch

Ethernet switches have more connections than splitters. This feature could make your computers more efficient.

Although a switch is slightly more complex, it’s still relatively straightforward. Plug your Ethernet cord into the port, and you’re ready to use it.

Many switches are energy efficient. They can tell which ports you’re not using and cut back on power accordingly. Also, they make more bandwidth available on a network, so your speeds don’t slow down as much as they would with a splitter.

Switches can control the flow of data to make sure your specific device gets information in a way that makes sense. Switches also protect the network.

A Word of Advice

As far as which one is better, get a switch. A splitter does the same job but isn’t as good at it, and it costs about the same.

A splitter doesn’t make the best use of your network and only gives you one more connection. A switch can add four or more new Ethernet ports with even faster speeds than the one you already had. There’s no better way to divide a signal than with a switch.

Why More Firms Use Ethernet Splitters

In today’s fast-paced world, having a solid and stable network connection is essential to get to your data at any time. Ethernet’s strong connection has made it the best choice for industrial, commercial, and office use.

New splitters and switches make traditional routers more powerful, so companies have enough connections. Switches are the best way to split an Ethernet connection, but they each have unique features.

Choosing the Best Ethernet Switch

It’s better to use Ethernet cables instead of Wi-Fi, even if your device has the option of using both. Wi-Fi is good, but Ethernet is the way to go if you want the fastest speeds and the best reliability.

Still, you want a switch with a good track record. The following switches have stood the test of time:

Netgear GS308
TP-Link TL-SG1008D
Trendnet Unmanaged Gigabit Switch

No matter what brand of switch you buy, there isn’t much difference in how they work. However, minor differences can make one more attractive than another.

Things to Look Out for When Purchasing an Ethernet Switch

The right Ethernet switch for your needs depends on how much it costs, how long it lasts, and how good it looks. However, speed is one critical thing you’ll have to watch out for.

The previous models are all Gigabit and full-duplex. This means they can run at 1000 Mbps in both directions simultaneously.

If you find a cheaper switch, it’s likely 10/100 Mbps. This means that the ports can only send and receive 100 Mbps in each direction, making them ten times slower.

A few dollars aren’t worth worrying about. You’ll be glad you bought a Gigabit switch even if the devices you currently need to connect are only 10/100. You’ll be glad you did this when you get something that can use those Gigabit speeds.
