Passive Power Over Ethernet Injector: What It Is and How to Use It
Passive Power Over Ethernet Injectors: What They Are and How They Work
Ethernet is a ubiquitous networking technology that powers the internet and countless other networks around the world. But did you know that Ethernet can also be used to provide power? That’s right, with the help of a passive power over Ethernet (PoE) injector, you can use an Ethernet cable to deliver power to a device that’s located up to 300 feet away.
In this article, I’ll explain what PoE is, how it works, and why you might want to use it. I’ll also provide some tips on choosing the right PoE injector for your needs.
What is PoE?
PoE is a technology that allows you to deliver power over an Ethernet cable. This means that you can use a single cable to transmit data and power to a device, such as a wireless access point, IP camera, or VoIP phone.
PoE is made possible by a special type of Ethernet switch that’s capable of supplying power to devices that are connected to it. These switches are typically powered by AC power, and they use a process called “inline power” to deliver power to devices over the Ethernet cable.
Inline power works by using the unused pairs of wires in an Ethernet cable to carry power. This means that you can use a standard Ethernet cable to transmit data and power to a device, without having to use a separate power cable.
How does PoE work?

Inline power works by using the unused pairs of wires in an Ethernet cable to carry power. This means that you can use a standard Ethernet cable to transmit data and power to a device, without having to use a separate power cable.
The PoE switch typically has a dedicated power supply that provides power to the Ethernet ports. When a device is connected to a PoE port, the switch detects the device and begins to supply power to it. The amount of power that’s supplied is typically between 44 and 90 watts, which is enough to power most PoE-enabled devices.
Why would you use PoE?
There are a few reasons why you might want to use PoE. First, PoE can be a convenient way to power devices that are located in difficult-to-reach places. For example, you could use PoE to power a wireless access point that’s located on the ceiling of a warehouse or a security camera that’s mounted on the side of a building.
Second, PoE can save you money on installation costs. By using PoE, you can eliminate the need for separate power cables, which can save you time and money.
Finally, PoE can improve the security of your network. By using PoE, you can reduce the number of cables that are running through your facility, which can make it more difficult for unauthorized users to access your network.
Choosing the right PoE injector
When choosing a PoE injector, there are a few things you’ll need to consider. First, you’ll need to decide how much power you need. Most PoE injectors can supply between 44 and 90 watts, but some models can supply up to 150 watts.
Second, you’ll need to decide what type of connector you need. Most PoE injectors have RJ45 connectors, but some models also have USB connectors or other types of connectors.
Finally, you’ll need to decide how many PoE ports you need. Most PoE injectors have one or two PoE ports, but some models have more.
Once you’ve considered these factors, you’ll be able to choose the right PoE injector for your needs.

Why Passive Power Over Ethernet Injector is Necessary
I have been using PoE (Power over Ethernet) for years now in my home network and it has been a great way to power my IP cameras, wireless access points, and other network devices. PoE is a very convenient technology that eliminates the need for separate power cables for network devices. However, there are a few cases where a passive PoE injector is necessary.
1. When the PoE switch is not located near the device that needs to be powered
In this case, a passive PoE injector can be used to extend the power from the PoE switch to the device that needs to be powered. The passive PoE injector simply takes the power from the PoE switch and converts it to a voltage that can be used by the device.
2. When the device does not support PoE
Some network devices, such as older printers, do not support PoE. In this case, a passive PoE injector can be used to provide power to the device. The passive PoE injector will convert the power from the PoE switch to a voltage that can be used by the device.
3. When the PoE switch does not provide enough power
Some PoE switches only provide a limited amount of power. If you need to power a device that requires more power than the PoE switch can provide, you can use a passive PoE injector to increase the power supply. The passive PoE injector will take the power from the PoE switch and amplify it to provide more power to the device.
Passive PoE injectors are a very useful tool for extending the power of PoE switches to devices that are not located near the switch or that do not support PoE. They are also a great way to provide more power to devices that require it.
My Buying Guides on ‘Passive Power Over Ethernet Injector’
What is a Passive Power Over Ethernet Injector?
A Passive Power Over Ethernet (PoE) injector is a device that provides power to a network device over an Ethernet cable. It does this by converting the power from the power source (usually a wall outlet) to a voltage that can be transmitted over the Ethernet cable.
Why do I need a Passive PoE Injector?
You may need a Passive PoE Injector if you have a network device that does not have its own power supply, such as a wireless access point or IP camera. By using a Passive PoE Injector, you can power the device over the same Ethernet cable that you use to connect it to your network.
What are the different types of Passive PoE Injectors?
There are two main types of Passive PoE Injectors:
- Unmanaged Passive PoE Injectors: These injectors are simple devices that do not require any configuration. They simply plug into a power source and an Ethernet port, and they will automatically start providing power to the device connected to the other end of the Ethernet cable.
- Managed Passive PoE Injectors: These injectors offer more features than unmanaged injectors, such as the ability to set the power output and to monitor the power usage of the devices connected to them.
How do I choose the right Passive PoE Injector?
When choosing a Passive PoE Injector, you will need to consider the following factors:
- The power output: The power output of the injector must be sufficient to power the device that you will be connecting to it.
- The number of ports: The injector must have enough ports to accommodate all of the devices that you will be connecting to it.
- The features: The injector should have the features that you need, such as the ability to set the power output and to monitor the power usage of the devices connected to it.
Where can I buy a Passive PoE Injector?
Passive PoE Injectors are available from a variety of online retailers and electrical suppliers.
A Passive PoE Injector is a valuable tool for powering network devices that do not have their own power supplies. By using a Passive PoE Injector, you can easily and efficiently power your devices over the same Ethernet cable that you use to connect them to your network.
