Power over Ethernet (PoE) is a standard that allows network cables to carry electrical power. It’s commonly used in IP phones, security cameras, and Wi-Fi access points. While the standard is helpful for devices that need power but don’t have an easy way to get it, there are different types of PoE. Not all are created equal, and some are better for specific applications than others. In this blog post, we will explore the 5 different types of PoE and their features. After reading this post, you’ll know which type of PoE is best for your application.
POE Injector
A Power over Ethernet (PoE) injector is a device used to connect devices that require power, such as VoIP phones or wireless access points, to a network. The injector provides the power by injecting it into the Ethernet cable that runs between the device and the network switch.
PoE injectors are available in a variety of different power levels, depending on the power requirements of the device they will be powering. For example, a VoIP phone may only require 2 watts of power, while a wireless access point may require up to 15 watts.
PoE injectors are also available in both desktop and rack-mountable form factors. Desktop PoE injectors are typically small and can be powered by an AC outlet. Rack-mountable PoE injectors are larger and must be powered by a DC input, such as a battery backup system.
POE Switch
A Power over Ethernet (PoE) switch is a network switch that has the ability to provide power to devices over the Ethernet cables. This can be useful for devices that require power but do not have an available power source, or for devices that are located in difficult-to-reach locations. PoE switches can also be used to provide backup power in case of a power outage.
POE Mid-span
As the name suggests, POE mid-span devices are positioned in the middle of a run of Ethernet cable, between the power source and the destination device. They receive power from either an external power source or a Power Sourcing Equipment (PSE) device, and pass that power on to the attached device. In most cases, mid-span devices are used to provide power to network cameras or phones that are located beyond the reach of a standard PoE switch.
POE Extender
Power over Ethernet (PoE) extenders are devices that are used to extend the reach of a PoE network. They are typically used in situations where the distance between two PoE devices is too great for a direct connection, or where there is a need to connect multiple PoE devices to a single network.
PoE extenders can be used to extend the range of a PoE camera system, or to connect PoE-powered devices in hard-to-reach locations. They are also commonly used to connect multiplePoE devices to a single network switch or router.
When choosing a PoE extender, it is important to select one that is compatible with the equipment that you are using. Many manufacturers offer proprietary PoE extenders that will only work with their own equipment. There are also a number of third-partyPoE extenders on the market that will work with most types of equipment.
When selecting a PoE extender, it is also important to consider the maximum distance that you need to extend the reach of yourPoE network. Most PoE extenders have a maximum range of about 100 meters (328 feet). If you need to extend the reach beyond this distance, you may need to use multiplePoE extenders or consider using fiber optic cable instead.
Hybrid Power over Ethernet
1. Hybrid Power over Ethernet
Power over Ethernet, or PoE, refers to a technology that allows network cables to deliver both power and data to devices. There are several different types of PoE, including 802.3af, 802.3at, and High Power over Ethernet (HPoE).
Hybrid Power over Ethernet is a new type of PoE that combines the benefits of both 802.3af and 802.3at. HPoE provides up to 30 watts of power, making it ideal for high-power devices such as video cameras and Access Points (APs). In addition, HPoE can deliver data at speeds up to 2.5 Gbps, making it perfect for applications that require high bandwidth.
Conclusion
There are a few different types of Power over Ethernet, each with their own benefits and drawbacks. Ultimately, the type of Power over Ethernet you use will depend on your individual needs and preferences. However, all types of Power over Ethernet can be useful in different situations, so it’s worth familiarizing yourself with each one. Thanks for reading!
