What is Ethernet?

Networking computers and other devices into a local environment, such as a home or office, began with the development of Ethernet in the early 1980s. A LAN (Local Area Network) is a local environment for creating, storing, and sharing information with other devices in that location. As a wired network, Ethernet began with coaxial cable and is now based on both copper wires and fiber optics.

A wide variety of Ethernet devices are now available on the market, so it is not uncommon for Ethernet devices and their uses to be amazed. Ethernet devices basically consist of computers, routers, switches, or other devices that meet the sole condition of having an internal or external network interface card (NIC).

What is an Ethernet hub and what kind of Ethernet hubs are there?

Ethernet Splitter is one of the many Ethernet devices available. Do not confuse Ethernet hubs with Ethernet Switches as they are not identical / similar. They perform completely different tasks, so they cannot be considered as similar products.

Because there are two types of Ethernet splitters, it is often difficult for us to make a clear distinction between the two, and usually people are not aware of the exact role of the Splitter.

Therefore, it is important to understand what the types of Ethernet hubs are and what the difference is between them.

There are two types of Ethernet hubs:

  1. Line Ethernet hub
  2. POE (Power Over Ethernet) hub

We will briefly describe each type of Ethernet hub.

Line Ethernet hub

Using an Ethernet splitter, users can run one cable through the floor, ceiling, and walls instead of two. However, users still need cables from the location of the devices. To achieve this, Ethernet hubs must be used in pairs. This Ethernet splitter can be used to reduce the need for Ethernet cables on your network. Two signals are transmitted on the same cable.

How does an Ethernet hub work?

One Ethernet connection can be split in two with an Ethernet splitter. Multiple devices can share an Ethernet signal if an Ethernet splitter is used. You can also share Ethernet connections with Ethernet switches and hubs, although they do it differently.

Ethernet hubs are available in two main formats:

  1. The following components are included in the small module: one Ethernet port, two Ethernet ports, and one short RJ45 interface cable: There is a wide variety of Ethernet hubs in this format on the market. This is useful when you connect an Ethernet cable to the RJ45 connector, for example, when the wall panels have an RJ45 connector.
  2. Three-port RJ45 adapter: If you want to connect with standard Ethernet cables, an Ethernet hub is more convenient.

Do Ethernet hubs reduce speed?

The federal question that comes to mind when deciding to use Ethernet hubs is “Do Ethernet hubs affect the performance of a connected Ethernet device?”.

The answer to this question is 100% / completely dependent on what types of networks you use in your local environment where splitters operate. Below is a picture that explains the above statement:

Sharing Ethernet cables is not a complete solution because their presence can affect the speed of network traffic. According to a professional study, Ethernet hubs reduce the data transfer rate from 1000 Mbps to 100 Mbps. As a result, it is safe to use an Ethernet hub with a 10 Mbps and 100 Mbps Ethernet connection, as LANs using Gigabit Ethernet slow down significantly when using a hub.

Ethernet-connected devices may perform worse due to slower speeds. Here is the problem. In addition, Ethernet hubs limit the number of devices per cable to two. So the number of devices connected via an Ethernet hub is not much higher than before. Line Ethernet hubs can only be used in pairs. One of the two Ethernet hubs is used to connect two cables into one and the other to redistribute the cable into two cables.

Unlike regular Ethernet, 10 and 100 Mbps Ethernets use only four of the eight wires in an Ethernet cable. Therefore, it is possible to nearly double the use of an Ethernet cable by running two separate links through it.

Power Over Ethernet (POE) hub

Another available Ethernet hub is the Power Over Ethernet (POE) hub.

Through the PoE splitter, power is supplied to devices that are not PoE-compatible by sharing information about the power. Power over Ethernet involves transferring power using an Ethernet connection to remote devices. Given that the current is direct current when the data is at a high speed, it is possible to transfer both at the same time without causing a real problem. Typically, splitters are used in low-power devices such as IP cameras, VoIP phones, RFID readers to separate the current from the data signal and help with the lower voltage required for conversion.

POE is also called POL (Power Over LAN)

Small devices without an external power supply can be used with Ethernet cables to facilitate installation. When power is not readily available or if additional wiring is difficult in less accessible areas, power over Ethernet is the ideal solution.

PoE systems are powered primarily through Ethernet switches. It is also possible to use a so-called Power over Ethernet injector. Thousands of standard non-PoE Ethernet switches are already in use, although switches with PoE capability are available. Power over Ethernet injectors are neatly placed between the Ethernet switch and the power supply and provide power that can be transmitted over a cable.

Advantages and disadvantages of an Ethernet hub:

Professional Ethernet Splitter:

  • The number of cables required to connect the two networks is not large.
  • If you only have one or two long Ethernet cables, you may need an Ethernet hub if you do not have enough Ethernet cables.
  • Using Ethernet hubs is a relatively inexpensive and efficient method of network sharing.
  • They are easy to install and do not require great equipment.
  • Ethernet hubs can be configured without software, making them stand out from most other network devices.

As a result, Ethernet hubs are the best solution for home networks with a limited number of connected devices — usually no more than two devices connected to a single router. No doubt you should use Ethernet hubs if you only need two devices to establish a 100 Mpbs connection.

Cons of an Ethernet hub:

  • Ethernet hubs can only be used when two devices are connected at a time, so if you want to connect more than two devices, this option may not be the most appropriate.
  • Despite the fact that fewer cables are needed to connect the two networks, two splitters are required for the installation to work properly.
  • You cannot use hubs if you have only one Ethernet port left on your router. Boom!
  • Due to its limited bandwidth, each Ethernet port can only provide 100 Mbps.
  • As a result, network resources capable of providing more than 100 Mbps are not completely improved.

Finally

Thus, Ethernet hubs are a valuable option in certain limited situations. Although Ethernet hubs are so old, they haven’t improved much, and their problems still exist. While they have advantages, they are still not a viable or workable alternative in most cases. When looking at the future of Ethernet hubs in light of today’s technological advances, there is still a lot of optimism.

In summary, this post defines what an Ethernet hub is and summarizes its functionality, advantages and disadvantages, and how it can be used. As a result of this tutorial on Ethernet hubs, you will have a deeper understanding of the subject.
