How To Pick The Best PoE Injector Adapter?

Considering the following factors help you to choose the best PoE injector adapter that can efficiently inject power into Ethernet cables to run your devices.

1. Standard and maximum power per port

The standard used for PoE type-1 or typical PoE injectors is IEEE 802.3af. The standard used for PoE+ or type-2 PoE injectors is IEEE 802.3at. Both these technologies use 2-pair PoE. The value of maximum power per port is 15.4W for PoE type-1 and 30W for PoE+.

PoE++ Type 3 injector adapters and PoE++ Type 4 injector adapter use IEEE 802.3bt. The maximum power per port is 60W for PoE++ Type 3 and 100W for PoE++ Type 4 injector adapter. Both of them use 4-pair Power over Ethernet cables.

A PoE injector adapter is only useful if it can offer sufficient power to your network devices. So, you must check the supported maximum power output before choosing a PoE injector adapter. The entry-level PoE injector adapters deliver up to 15W power whereas the higher-end PoE injector adapters deliver up to 60W power.

2. Maximum transmission range

It is important to note that although you use a PoE injector adapter, the power within your wired network will decline with the distance. This happens due to attenuation that implies that the power over Ethernet is restricted by the distance of the wired network. So, you must consider the maximum transmission range before buying a PoE injector adapter. Usually, many reliable PoE injector adapters support up to 100 meters (or 328 feet) of transmission range which is enough to ensure efficient transmission.

3. Data Speed

The data transmission speed of PoE injector adapters can be different for different brands. The data speed is up to 1 Gbps (speed options are 10/100/1000 Mbps) over Cat5e and Cat6 cables. Those PoE injector adapters implemented with IEEE 802.3bz technology deliver data transmission speed in the range of 2.5 to 5 Gbps over Cat5e and Cat6 cables.

4. IEEE Compliance

Your PoE injector must be IEEE compliant with the latest standards to provide the best performance and excellent network compatibility. It is recommended to buy the ones that are 802.3af or 802.3at compliant. This is because they deliver fast speed and consume less power.

5. Security features

PoE injector adapters work as mediators between the device and the network switch. Security is a crucial factor to consider in ensuring safe data transmission. The reliable PoE injector adapters are been designed to protect the whole network against overloading, over-voltage, over-current, underpower, and interference. It is better to buy the one with these security features so that you can realize safe and reliable data transmission.

Frequently Asked Questions When Picking PoE Injector Adapter

1. How do you connect a PoE injector to a wired connection to deliver power output?

Any PoE injector is equipped with two ports. One of the ports works as an input from the network and the other one works as an output to the network. After connecting both these ports, your PoE injector will be a part of the network. So, it simultaneously offers power output and bypasses data packets.

2. What are the different options PoE Injectors use to remotely control the connected devices?

PoE injector handles both data and power transmission, so you can restart the connected devices either manually or depend on a schedule. You can use the remote connectivity option to simplify the process of analyzing and managing connected devices.

3. How do active PoE injectors ensure the safety of the connected devices?

Generally, active PoE injectors intelligently assess the power supply and feed it to the devices as per their needs. This functionality avoids the overloading of devices and also saves a considerable amount of power. So, the devices connected to the PoE injectors don’t burn out easily and safely receive the power.

4. How do PoE injectors decrease installation costs?

PoE-powered devices can be installed in areas where there is no power outlet around. You don’t need to hire an electrician to run circuit paths. You can effortlessly install the PoE injector and configure the device yourself. Usually, these injectors are designed with clear indications of the installation process. They don’t need extra wiring or an electrician and hence decrease the installation costs.

Final Thoughts

PoE injector adapters provide an alternative power substitute to various devices like switches, access points, panels, IP cameras, VoIP phones, and more. They don’t require a wireless connection and you can flexibly install them anywhere. They simplify the setup of electronic devices and also decrease expenses for network management and maintenance. The best PoE injector adapter allows you to easily configure the mentioned devices without compromising safety and reliability.
