A Look At The Difference Between An Ethernet Switch, Hub, and Splitter

The demand for Ethernet, as one of the most commonly used types of cable in hard-wired Local Area Networks (LAN) today, is higher than ever. And while that’s the case, it’s worth noting that almost all routers in use today have a limited number of usable ports, restricting the number of devices that can be plugged in into a router at one go. This is an issue in homes and offices that need to connect multiple network devices and computers without using WiFi. One way to circumvent this problem is through Ethernet splitting, which essentially entails the use of dedicated devices that are designed to expand a network.

If you’re currently short on Ethernet ports, there are different options you can use to split your network. They include splitters, switches, and hubs. Each of these options functions differently from the other, with each having its drawbacks and benefits. Before extending a connection or network, there are several factors that you need to consider first. These factors include flexibility, security, speed, reliability, and the number of connections you need. While ethernet switches are popular and quite flexible, you still need to take a moment to consider which option best suits your office or home needs.

Why’s Ethernet Important?

Ethernet, unlike WiFi, is a wired protocol. In typical settings, Ethernet cables run from a router or modem to the RJ45 port on a device connected to the network. Most of the benefits of using Ethernet are related to the fact that devices connected to the network are joined by cables, and are therefore less likely to be affected by wireless security threats or experience connectivity issues. Depending on the protocol and size of a network, these cables can either be an optical fibre, coaxial, or twisted pair.

Despite physical cable requirements, Ethernet remains to be the universal standard for connecting more than one device over a single network for enhanced communication. Ethernet cables produce a very reliable connection and impressive network speeds. Apart from that, these cables are less prone to security threats compared to other protocols and typically have very little latency and interference. It’s due to all of this that ethernet is considered to be the most dependable solution for seamless, high-speed, and confidential data transmission.

What’s an Ethernet Switch?

Ethernet switches are high-speed networking devices that contain a few extra ports. These devices are the preferred method for ethernet splitting due to their ability to split a single connection into multiple connections with minimal interference. Ethernet switches use a single port to connect to a router with all extra ports being made available for other devices to connect to the network. Each client on the network is given a unique network address, making it easier for the switch to direct traffic. Ethernet switches are available in a variety of sizes and speeds and can have anywhere from 5 to 52 ports.

The device splits the network into smaller, less congested pathways through a process known as packet switching. Packet switching, on the other hand, is the process of transferring small data segments across a network for more efficient and faster delivery. Devices connected to the switch receive the bandwidth they need without any intrusion from other network traffic. This is possible since the connection to each device is an individual pathway that doesn’t slow down or affect the overall network. Since ethernet switches provide full-duplex communication, data on the network can be sent and received simultaneously, improving overall network speeds.

Internet switches provide a fast link with very little interference, making them the perfect choice for environments that carry significant traffic from multiple devices. This is one of the best solutions for creating extra ethernet ports as they come with features and configurations to suit different situations. It’s benefits such as these that make ethernet switches the go-to ethernet splitting solution.

However, it’s worth noting that there are a few drawbacks to using ethernet switches. While they provide minimal interference compared to other options, users may still experience slow connections when several devices on the network stream at the same time. Nevertheless, the connection is still more consistent and stable than most, if not all wireless options.

The other thing to note about ethernet switches is that they require a bit of setting up and can’t operate without a power supply. This ultimately makes them less ideal for basic network splitting needs. Power input is needed to split the signal into several signals that work at the same time. There’s also the fact that Ethernet switches are generally more expensive than splitters and hubs. Nevertheless, there are lots of affordable switches on the market today that are worth the cost when the additional functionality and flexibility are taken into account.

What’s an Ethernet Hub?

Ethernet hubs, like switches, connect to a router through a single cable and have multiple ports that several devices can use to connect to the network. And while ethernet hubs connect multiple devices, the difference is that they make them work like one network segment. Ethernet hubs create more connections by repeating the traffic they receive.

Hubs, unlike switches, utilize what’s known as half-duplex communication meaning that devices on the network can’t receive and send data at the same time. They, in comparison to switches, reduce connectivity speed considerably and cause more interference between linked devices. It is due to this that they’ve been replaced by Ethernet switches for virtually all ethernet applications.

The ethernet hub successfully extends a network, creating more connections for multiple devices. They are also quite cheap compared to their more advanced counterpart. However, it’s worth noting that ethernet hubs may, sometimes, be the best solution for some applications. For instance, an ethernet hub could be more effective for protocol diagnosis thanks to its half-duplex communication operation, which makes it possible for the device to view all the traffic transferred over the network to any of its ports. Switches, on the other hand, restrict port traffic, meaning that the only thing diagnostic tools can view is broadcast messages.

Hubs, however, aren’t the most efficient solution for extending networks in most applications. This is because they tend to produce high interference between wasted bandwidth, separate network devices, and slowed connections due to data collisions. Users can easily notice this when running multiple devices through the device at the same time. As the technology behind ethernet switches continues to improve, their prices have become as competitive as those of ethernet hubs, something that’s led to hubs being nearly rendered obsolete. While you can use an ethernet hub to extend a network, there are better options today that are far more reliable, functional, and affordable.

What’s an Ethernet Splitter?

Of all network splitting options, ethernet splitters are the most basic and simplest way of splitting a network connection. Splitters work as coaxial cable transmission systems that divide a single cable into two, allowing users to run one cable through ceilings and walls but still need two cables for each connected device. These devices essentially eliminate the need to run more than one ethernet cable between rooms but do not increase the number of devices that can be connected. It’s worth noting that ethernet splitters have to be used in pairs to split the cable back into two for the network devices.

Ethernet splitters exploit the fact that 100 Mbit and 10 Mbit ethernet only need four wires although most cables contain eight. The device reduces data throughput and the number of used wires into two ports, meaning the max. bandwidth is 100Mbs per second.

Splitters are passive, meaning that, unlike switches and hubs, they don’t require a power supply. They are also the most straightforward network splitting option available and are very intuitive to use and set up. Their simple form factor and forthright operation make them the cheapest option for dividing ethernet connections. These devices are the perfect solution in situations where you need to reduce the number of network cables travelling between one room and another in an office or home.

When it comes to ethernet splitting, ethernet switches are the best solution for splitting a network in most cases since splitters have some major drawbacks. Devices connected to the network are limited to slower speeds of 100Mbit. With this option, there is a limited number of connected devices since splitters don’t increase the number of connected devices; well unless it is used in conjunction with an ethernet switch. The destination network router must have at least two open ports that a splitter can use, which isn’t always the case. If you are looking to extend a network connection, then you better consider using an ethernet switch.


In today’s fast-evolving world, a strong and dependable network connection is essential to anyone that needs instant access to data. Thanks to Ethernet’s robust connectivity, it has now become the number one choice for offices and homes. However, to ensure that you have enough network connections for all your devices at home or in the office, what you need is new network devices like switches, hubs, and splitters that can extend the abilities and capacities of traditional routers. Of all available options, ethernet switches are your best bet when it comes to splitting ethernet connections. But that doesn’t necessarily mean that splitters and hubs don’t have their specific functions and benefits.

Beyond personal use, the impressive functionality and speed provided by ethernet go a long way in driving and improving innovation. Instant access to data and information enables new tech like industrial ethernet and the internet of things. The reliable and fully connected network system that ethernet provides is helping revolutionize industries across the globe including retail, manufacturing, and healthcare, amongst others.
