Welcome to our all-inclusive guide to Power over Ethernet PoE splitters! This guide is perfect for those who wish to power devices that do not support IEEE802.3 standards based PoE but want to utilize a PoE network infrastructure.

In this article, we’ll explore everything about PoE splitters. We’ll discuss their roles, advantages, and the most effective methods for incorporating them into network installations. So, let’s start!

Understanding PoE Technology

Before delving into PoE splitters, it’s crucial to understand the basics of PoE technology. PoE simplifies network installations by transmitting both electrical power and data over a single Ethernet cable, eliminating the need for separate power supplies. This technology is especially useful for devices like IP cameras, wireless access points (WAP), kiosks, and VoIP phones, often installed where power outlets are scarce.

What is a PoE Splitter?

A PoE splitter separates the power and data signals from a PoE-enabled Ethernet cable. It receives the combined power and data input and splits it into separate outputs for power and data. This allows non-PoE devices to utilize PoE infrastructure, simplifying the integration of various devices into your network.

How Does a PoE Splitter Work?

A PoE splitter works by connecting to a PoE-enabled Ethernet cable and splitting the power and data into separate outputs. Here’s a step-by-step breakdown:

PoE Switch and PoE Injector: With this setup, a PoE network switch connects to a PoE splitter using an Ethernet cable.

Non-PoE Switch and PoE Injector: This setup starts with a non-PoE network switch connected to a PoE injector via an Ethernet cable. The PoE injector then connects to a PoE splitter using another Ethernet cable.

Input Connection: The PoE splitter receives both power and data through a single Ethernet cable connected to the splitter’s RJ45 input port.

Splitting Process: The splitter’s internal circuitry separates the power and data signals.

Power Output: The higher voltage PoE input (56V DC) is converted to a fixed output voltage that the non-PoE device requires. The voltage output depends on the type of PoE splitter model that offers a fixed voltage (5V, 12V, 24V). 

Data Output: The data signal is allowed to continue to connect to a device via a standard Ethernet connection.

Output Connections: The splitter provides two outputs: one for power (which typically uses a barrel connector), and one for data through an RJ45 output port, which goes into the input of the non-PoE device through an Ethernet cable.

Benefits of Using PoE Splitters

PoE splitters offer several advantages in network installations:

Flexibility: PoE splitters allow you to use existing PoE infrastructure to power non-PoE devices, providing greater flexibility in your network design.

Cost-Effective: By leveraging PoE technology, you can reduce the need for additional power supplies and electrical wiring, lowering installation costs.

Types of PoE Splitters

Power over Ethernet (PoE) splitters are versatile devices tailored for specific applications, each type catering to distinct needs within network setups. Understanding these variations is crucial for optimizing PoE deployments. Here are the most common types of PoE splitters:

Pass-Through PoE Splitters

These splitters do not regulate the output voltage and are typically used for equipment that doesn’t have PoE front ends but have internal DC-DC converters. They pass through the power and data without any modification. Although they are more affordable than regulated output PoE splitters, their simplicity can also be a drawback in certain scenarios. Since they lack voltage regulation, pass-through PoE splitters can not be used for devices that require precise voltage levels. Additionally, the lack of standardized specifications for passive PoE can result in compatibility issues between different manufacturers’ equipment, requiring careful consideration during setup and deployment.

Regulated Output PoE Splitters

Regulated output splitters, unlike pass-through splitters, convert the output to a specific actively regulated voltage to perfectly match what each device needs, ensuring stable performance. This makes them super reliable and versatile. They also stick to standardized specs, which means less hassle with compatibility between different devices. Some even come with bonus features like surge protection, making your network setup more robust. Overall, if you’re looking for consistent performance and fewer headaches, regulated output PoE splitters are the way to go.
