Power over Ethernet can provide a data connection and power supply within 100 meters. Is that insufficient for your system? No worries; you can purchase a PoE extender that can increase the range.

PoE is a fascinating technology that offers us two basic things: power supply and data connection. Nowadays, each of our systems works online and offline. If the internet connection breaks down, you can imagine its results. According to an estimate, it will cause a massive halt to economic and financial services. Even if the internet speed slows down, the impact will be less severe but almost the same. The power over Ethernet technology supports the online system with massive data speed.

To learn more about PoE, consider the following: What is PoE?

How does PoE technology work?

Institute of Electrical and Electronics Engineering invented the PoE technology in 2003. If they introduced it, they must have defined the principles upon which it works. Yes, there are three primary standards of PoE upon which it operates.

  • PoE 802.3af
  • PoE 802.3at
  • PoE 802.3bt

PoE 802.3af is the earliest version of PoE, while others are upgrades. These three basic versions of PoE 802.3 work in the system. For example, if your PoE switch is compatible with the 802.3bt standard, it will work according to the principles defined by this standard. It will provide a high-speed data connection of up to 100GBs per second and empower devices with power up to 100 watts at maximum.

From other standards, you can expect a specific voltage and power range. For a detailed analysis of PoE standards, look at the article —What is PoE Standard?

What is the maximum distance for PoE technology?

PoE technology offers a maximum range of 100 meters. This is far better than Wi-Fi or other network technology. Moreover, there is no change in speed if you are within the network’s range.

Do you have Wi-Fi at your home for a data connection? I suppose you are sick of the Wi-Fi’s short range. Wi-Fi usually allows a maximum distance of 10 meters. In addition, speed is affected if the length of the Wi-Fi router increases.

How do I run PoE over long distances?

In industrial Ethernet, there is a need for PoE technology to be long-range. If the 100-meter range is insufficient, you can try other mechanisms to increase the capacity.

One of those mechanisms includes the installation of PoE extenders. Let’s have a quick go-through of PoE extenders.

What is a PoE extender?

Just focus on the word “PoE extender.” It is a device that extends PoE attributes and can expand the distance of power over an Ethernet system.

If you install the PoE switch in your network, you can get a data connection up to 100 meters. Sometimes, this range is not sufficient when your devices are far away from each other and your device can not get a high-speed data connection. This is an actual problem that causes you to use the PoE extender.

How does it work?

A PoE extender acts in between the PoE switch and your device.

Let me help you understand this concept by giving an example of an IP camera and PoE switch. We use the IP camera for surveillance purposes, especially at outdoor places. What if it is far from the PoE switch? I’m talking about a distance of more than 100 meters.

In this case, PoE can’t reach the IP cameras. What will be your first response to adjust the distance? It would help if you used the PoE extender to connect the PoE switch and IP camera.

The PoE extender receives data from the PoE switch and transfers it to your IP camera. So simple! That’s how the PoE extender increases the distance.

How can you install the PoE extender?

PoE extenders are just plug-and-play. You don’t have to hire IT specialists to install.

You must correct one Ethernet port with the switch and the other with the IP camera. That’s all you have to do. The PoE extender will get the data and power supply from the switch. Then, it will transfer to your device.

If you are looking for a PoE extender that can increase the range of up to 800 meters, HoweVision PoE extender can be the right one.

Do I need a PoE extender for my PoE system?

The answer is not that simple. It depends on multiple factors. One of the most important factors is your need for it. For example, if your devices are more than 100 meters away, you might require the PoE extender. In industrial PoE, you can observe this scenario even more effectively.

So, it would help if you had a PoE extender when there are ultimate requirements for increasing the distance.

What are the benefits of using PoE extenders in the system?

PoE extenders can be very helpful in every aspect. They can enhance the length without affecting the quality of the network. Here are some benefits of PoE extenders in your system.

It can increase the length of the PoE network.

What is the ultimate goal of the PoE extender? To run the Ethernet cable over a long distance. That’s what you can expect from a PoE extender. If 100 meters is not a reasonable range for you, PoE extenders provide up to 10 times its range.

It is just a plug-and-play switch.

Are you tired of hiring IT specialists for all your networking systems? If so, there is no need to worry about the PoE extender. They are just like simple plug-and-play hardware devices. You have to connect the Ethernet ports with the switch and your device. No other unique mechanism is an essential feature to install. Great, right?

PoE extenders save you bucks.

PoE extenders are cheap compared to other mechanisms. Instead of investing in different instruments to increase the PoE distance, go for the extenders. They can save bucks for two reasons. First, you don’t have to employ an IT expert to install them. Second, these are cheaper options than installing other network systems.

They don’t affect the quality of the network.

Quality performance is the main problem you might assume will decrease with the PoE extenders. Don’t worry about it. PoE extenders are just intermediary devices that transfer data and power from the switch to your device. There are no effects on network performance while increasing the length.
