How Does an Ethernet Splitter work?

An Ethernet splitter allows you to have different outputs, i.e. different direct connections to your network, starting from a single input cable. In this case, starting from a single signal output, it is possible to connect specific splits which in turn can be connected to multiple devices at the same time.

The signal which is sent in the form of impulses within the single cable is automatically distributed within a specific compartment, hermetically closed. Within it, the different connections are then associated with two or more Ethernet outputs. 

At this point, once you have connected your devices, it will be possible to benefit from different signals using a single central hook-up cable.

How to Choose the Best Ethernet Splitter? [Buying Guide]

Now that we understand the simple operation of an Ethernet splitter, we can now move on to the actual selection process. 

Although the function of the splitters, or Split Ethernet, is almost the same, it is possible to identify different products, associated with different characteristics. 

In order to avoid buying a product that is not suitable for your needs, it is therefore important to keep in mind some important precautions.

1. Number of Outputs

The starting point is certainly the one on the number of outputs. Despite the name of “splitters”, which could imply a bifurcation with only two outputs, currently, there are devices capable of dividing the signal into different outputs. 

Also, in this case, based on your needs, but above all on the number of connections you need to obtain. It will be possible to choose the most suitable product.

2. Cable length

A second element to keep in mind concerns the length of the cables. Very often, the splitters consist of a box containing the different output ports (metal or plastic), connected to a cable to be hooked to the network. 

The length of this cable may be relevant, depending on the proximity or distance of your computer or another compatible device.

3. Control and Management 

The control and management systems represent a further aspect to be verified. For example, it is possible to recall how many products, especially if they are of excellent quality, have automatic shutdown functions for unused outputs. 

In addition, it is advisable to purchase Ethernet splitters that do not require manual configurations and that can be installed in a few seconds.

4. Power Supply

Although this is an impractical option, splitters that have an external power supply directly connected to the power outlet can offer better quality in signal transmission.

They are in fact more powerful and have a lower risk of suffering potential interference. However, the vast majority of models on the market, especially if they have two to four output ports are able to draw the energy necessary for their operation by connecting with other devices; HDMI power splitter

Does the Price Matter?

The vast majority of ethernet port splitters do not require a particularly high investment. Mostly, models with two, three, or four outputs are between $10 and $ 20, even with 4K and 3D support. As we have already anticipated, things change when one focuses on more complex products, most widespread in the workplace.

Splitters that reach eight outputs, in fact, can even exceed $60. If you are looking for a product for domestic use, most of the models on the market can offer good quality. But if you can spend a slightly higher amount it is advisable to evaluate whether a higher price also corresponds to the use of more durable materials and better quality connectors.

Is the Brand Important?

Being quite simple accessories, ethernet splitters are produced by many not particularly well-known brands. 

However, there are some companies that have won the trust of many users thanks to the excellent value for money of their products. These, unlike other brands that occupy this type of market, generally also ensure a decent after-sales service.

Are the Materials Important?

Considering that it is unfortunately impossible for the average user to verify the quality of the materials with which the internal components of an ethernet splitter are made, the only element that can be evaluated is the external body. 

Many models use plastic, while some have metal finishes. Depending on the use you want to make of the splitter and how it will be positioned. It is advisable to orient yourself to more or less solid materials. It is important to choose a rather sturdy model that can withstand bumps and scratches.

How to Connect Ethernet Splitter?

Now that we have seen the best products on the market many will wonder how to connect an Ethernet splitter. In this regard, the only connections to be made concern the connection to the network, i.e. from where the device will draw the signal and subsequently the connection to the various electronic devices of its interest.

Specific splitters could also be equipped with an electrical power supply. In this case, it will be necessary to connect them to an electrical outlet and then proceed with the same connections mentioned above. In summary, the split is connected to its modem, which, taking the network from the outside, conveys it via cable to the inside of the splitter.

At this point, the ports of the splitter can be used to connect PCs, printers or consoles, in order to obtain a much more powerful signal than simple Wi-Fi connectivity.

Frequently Asked Questions

Q1. Do Ethernet cable splitters work?

A1. Yes, they do work. They can be a temporary and less costly solution for dividing your ethernet traffic. However, they do slow down the speed of the service sometimes.

Q2.  Is there a Cat 5 splitter?

A2. Most of the splitters available in the market support Cat 5 and even its successors such as Cat 6, Cat 7, Cat 8, etc.

Q3. Does a splitter slow down the internet?

A3. It purely depends on the way the splitter is installed. If installed properly it should not have any effect on the speed but sometimes it does slow down the speed.

Q4. What is the use of the RJ45 splitter?

A4. It basically allows two different computers to share the internet. It can be used in place of a network cable.
