What Is PoE Stand For?

Ethernet is a type of computer networking technology that has been around for several decades. It’s used in both home and office networks to connect devices to the internet. Ethernet uses cables to connect devices, and each cable has a specific purpose. One of the more recent developments in Ethernet is Power over Ethernet, or PoE. This standard allows electrical power to be carried by an Ethernet cable in addition to data. This can be useful in situations where it’s not possible or convenient to provide power to devices using a separate power cable. In this article, we’ll take a closer look at PoE and how it works.

The History of PoE

PoE stands for Power over Ethernet. This technology has been around for many years, but it wasn’t until recently that it started to be used in homes and businesses.

PoE is a great alternative to traditional methods of powering devices, such as through a power outlet. It offers a number of advantages, including the ability to deliver power through Ethernet cables. This means that you can use existing Ethernet infrastructure to deliver power to devices, which can save on installation costs.

PoE is also very flexible in terms of the amount of power that it can provide. It can be used to power anything from small devices like IP phones to large devices like LCD TVs.

PoE has been around for many years, but it wasn’t until recently that it started to be used in homes and businesses. The first PoE standard was 802.3af, which was ratified in 2003. This standard provides up to 15 watts of power per port and is commonly referred to as “Type 1” PoE.

In 2009, the 802.3at standard was ratified, which increased the maximum power output to 30 watts per port. This is commonly referred to as “Type 2 PoE”.

Most recently, the 802.3bt standard was ratified in 2018. This standard provides up to 60 watts of power per port and is commonly referred to as “Type 3” or

What PoE Does

PoE is an Ethernet standard that allows network cables to carry electrical power, along with data. This lets you power devices such as IP phones, security cameras, and WiFi access points over a single cable. PoE is short for Power over Ethernet.

The Different Types of PoE

There are three different types of Power over Ethernet:

1. Passive PoE – This is the most common type of PoE, and is typically used for devices such as IP phones or cameras. The power is injected into the Ethernet cable using a special injector, and the device itself draws the power it needs from the cable.

2. Active PoE – This type of PoE is less common, and is typically used for devices that require more power than what passive PoE can provide. Active PoE injectors use a higher voltage to provide power to the device, and the device itself regulates the voltage to ensure that it doesn’t damage the equipment.

3. High-Power PoE – This is the newest type of Power over Ethernet, and can be used to power devices that require up to 60 watts of power. High-Power PoE injectors use a special high-voltage cable to provide power to the device, and the device itself regulates the voltage to ensure that it doesn’t damage the equipment.

Conclusion

So, what is PoE stand for? Power over Ethernet. It’s a great technology that allows you to deliver both power and data over a single Ethernet cable. And it’s becoming more popular as more devices are designed to use it.
