If you’re not familiar with Power over Ethernet (PoE), it’s a technology that allows you to transmit electrical power along with data signals over standard Ethernet cable. This is useful for devices that need to be powered but are located in difficult or hard-to-reach places. While PoE is a great technology, it’s not without its limitations. One such limitation is that some devices require more power than what can be delivered by PoE. This is where PoE converters come in. In this blog post, we will explore the need for PoE converters and how they can help deliver the power your devices need. We will also touch on the different types of converters available and their applications.
What is PoE?
PoE (Power over Ethernet) is a standard that allows networked devices to receive power through the same Ethernet cable that they use for data connectivity. This enables devices such as VoIP phones, IP cameras, and wireless access points to be powered without the need for a separate power cable. PoE converters can be used to connect non-PoE devices to a PoE network.
How does a PoE converter work?
PoE converters work by taking the standard 48 volt power that is provided by PoE injectors and swapping it out for the 12 or 24 volt power that is required by non-PoE devices. This process is made possible through the use of a step-down transformer, which steps down the voltage from 48 volts to the lower voltage required by the device. In addition to transforming the voltage, PoE converters also provide protection for devices against surges and spikes in voltage that can damage sensitive electronic components.
What are the different types of PoE converters?
There are four different types of PoE converters: Ethernet over twisted pair (EoT), Ethernet over coaxial cable (EoC), Ethernet over fiber optic cable (EoF), and Ethernet over power line (EoPL).
Ethernet over twisted pair is the most common type of PoE converter. It uses standard Ethernet cabling to connect devices to a PoE switch or injector.
Ethernet over coaxial cable is used in situations where there is already coaxial cable infrastructure in place. It can be used to connect devices to a PoE switch or injector, or to extend the range of an existingPoE network.
Ethernet over fiber optic cable is used when long distances need to be covered, or when higher bandwidth is required than what twisted pair or coaxial cables can provide. Fiber optic cables are much thinner than other types of cables, making them easier to route through tight spaces.
Finally, Ethernet over power line is used to connect devices that are not near a network connection, such as in a warehouse or parking garage. EoPL uses the existing electrical wiring to create a PoE network.
A PoE converter can be a very useful tool for anyone who needs to connect devices that use different types of power. By converting the PoE from one device to another, you can save money and time by not having to buy or install separate power supplies for each device. With a PoE converter, you can also keep your devices connected even if there is a power outage.
