The Basics of PoE Technology

PoE, or Power over Ethernet, is a type of technology that allows you to power network devices over an Ethernet cable. In other words, you can use an Ethernet cable to both transmit data and deliver power to devices like IP cameras, VoIP phones, and access points. In this blog post, we’ll cover the basics of PoE technology and explain how you can use it in your business.

How PoE Works

PoE technology works by using a process called injector power dissipation. Basically, this process allows electrical current to be transmitted along the same wires that are used for data transmission. The voltage is typically around 48 volts, and the current is around 350 milliamps.

One of the benefits of PoE technology is that it offers a lot of flexibility when it comes to powering network devices. For example, you can use a single Ethernet cable to connect an IP camera to a network switch that is located up to 100 meters away. This makes it ideal for applications where there is no convenient source of power available.

Another benefit of PoE technology is that it can make installation and setup much simpler and quicker. This is because you don’t need to worry about running separate power cables to each device. All you need is a single Ethernet cable.

Types of PoE Technology

There are two main types of PoE technology: endspan and midspan.

Endspan PoE technology injects power into the Ethernet cable at the network switch. Midspan PoE technology uses special midspan units that are placed between the network switch and the powered device.

Endspan PoE technology is typically used for devices that are located close to the network switch, as it doesn’t require any additional hardware besides the switch itself. Midspan PoE technology is typically used for devices that are located further away from the switch, as it offers more distance between the switch and the powered device.

Considerations When Using PoE Technology     

There are a few things you should keep in mind if you’re thinking about using PoE technology in your business:

1) Make sure your network infrastructure is compatible with PoE-enabled devices;

2) Consider what type of cabling you will need;

3) Determine how much power your devices will require;

4) Consider what challenges you might face with heat dissipation.


PoE technology offers a lot of benefits for businesses, including flexibility, simplicity, and increased installation speed. However, there are also a few things you should keep in mind before using PoE in your business, such as compatibility and heat dissipation challenges. Overall, though, PoE can be a great solution for powering networked devices in your business.
