Have you ever encountered the problem of needing to connect a non-PoE device to a PoE network? It can be quite frustrating when you have a mix of PoE and non-PoE devices and struggle to find a solution that allows them to work together seamlessly. This is where a PoE splitter comes in handy. In this blog post, we will explore what exactly a PoE splitter is, how it works, and how to use it effectively.
What is a PoE Splitter?
A PoE splitter is a device that splits the power and data signals from a single Ethernet cable into two separate cables. The splitter is typically connected to a PoE switch or injector to power non-PoE devices such as IP cameras, wireless access points and VoIP phones. By using a PoE splitter, you can simplify your network setup, reduce the amount of cabling required, and provide power to devices that are located in areas where power outlets are not readily available.

What Are the Benefits of a PoE Splitter?
1)Compatibility: A PoE splitter offers a simple and effective solution for connecting non-PoE devices to a PoE network. It allows you to bridge the gap between PoE and non-PoE devices, making them compatible with each other.
2)Cost-Efficiency: Instead of investing in new network equipment or replacing your non-PoE devices, a PoE splitter allows you to use your existing non-PoE devices by simply splitting the power from the Ethernet cable.
3)Convenience: With a PoE splitter, you no longer need to worry about having separate power sources for your non-PoE devices. It eliminates the need for additional power cords, power outlets, and potential cable clutter.
4)Flexibility: A PoE splitter provides flexibility in terms of device placement. You can now connect your non-PoE devices anywhere within the reach of an Ethernet cable, without being limited by the availability of power outlets.

How Does a PoE Splitter Work?
The PoE splitter is often used with a PoE switch or a PoE injector. The PoE injector is responsible for injecting power into the Ethernet cable, while the splitter separates the power from the data signal, delivering it to the non-PoE device. The combined power and data signals from the PoE injector are sent through a single Ethernet cable to the PoE splitter. Inside the PoE splitter, there is circuitry that separates the power from data and directs it to an independent power output on the PoE splitter, typically a DC jack, USB port or RJ45 port. Simultaneously, data is carried through a separate path to a non-PoE device.

How to Use a PoE Splitter?
Using a PoE splitter is relatively straightforward, but there are certain steps you need to follow for a successful setup:
Step 1: Identify Your PoE Source
Since the PoE splitter cannot be connected to a network switch directly, make sure you have a PoE switch or injector as the power source. If you have a larger network with multiple PoE devices, a PoE switch may be more suitable. If you have a smaller network or want a cost-effective solution without replacing your existing network switch, a PoE injector might be the better choice. Just ensure the total power budget of the PoE switch or injector is sufficient for the devices you are connecting, including the PoE splitters and the non-PoE devices powered by them. Additionally, check their compatibility and specifications to ensure seamless integration.
Step 2: Select the Correct PoE Splitter
When choosing a PoE splitter, there are several factors to consider. First, you need a PoE splitter that can provide enough power to accommodate all the devices without overloading. If your device requires 60W, choose a PoE splitter with a matching or higher power rating. Furthermore, ensure that its voltage output matches the voltage requirements of your connected devices. Fastcabling has developed a 12V PoE+ splitter (5723-19) that delivers a power delivery of 30W with a default 12V DC output for devices such as IP cameras and WAPs. What’s more, some PoE splitters may limit data speeds to 1Gbps. If you require high speeds, ensure both the PoE injector and PoE splitter support the desired data speed.

Step 3: Connect the PoE Injector and PoE Splitter
When you get everything ready, start by connecting the PoE injector to a power source, and make sure the injector is properly powered up before proceeding. Take an Ethernet cable and plug one end into the PoE injector’s LAN port, and the other end into the network switch or router. Then, take another Ethernet cable and plug one end into the PoE injector’s PoE output port, and the other end into the PoE splitter’s PoE input port.
Step 4: Connect the Non-PoE Device to the PoE Splitter
Attach your non-PoE device to the PoE splitter using the appropriate power connector. This could be a DC jack, USB port, or any other compatible power input. Then, take an Ethernet cable and plug one end into the data port of the splitter and connect the other end to the Ethernet port on the non-PoE device. Finally, secure all connections to prevent accidental disconnections or damage. If possible, use cable ties or other means to organize and secure the cables.
Frequently Asked Questions
Q1: Can I use PoE splitters for devices with different voltage requirements?
A: PoE splitters typically come with specific voltage outputs. It’s important to ensure that the voltage output matches the requirements of your device because using the wrong voltage may damage the device.
Q2: Can PoE Splitters be used in daisy-chaining configurations?
A: While possible, daisy-chaining PoE splitters may cause power loss and is generally not recommended. It’s typically better to use a separate PoE splitter for each device.
Q3: Are PoE Splitters weatherproof for outdoor use?
PoE splitters come in different designs, and not all are suitable for outdoor use. If you need an outdoor solution, choose a PoE splitter specifically designed for outdoor or industrial environments. Fastcabling has developed an 802.3bt outdoor PoE++ splitter (5721-46) that comes with an IP67-rated waterproof metal enclosure and features a wide working temperature range of -45~70℃, ideal for use in harsh environments.
Q4: What safety precautions should I take when using PoE splitters?
A: Follow standard safety precautions, such as ensuring proper insulation, avoiding exposure to water, and using equipment that complies with safety standards. Consult the manufacturer’s guidelines for specific safety recommendations.
Q5: Can PoE splitters transmit data over long distances?
A: PoE splitters are primarily designed for power delivery, and the distance over which they can transmit data is influenced by factors such as cable quality. The maximum distance for PoE is limited to 100 meters, while excessive length cable can lead to power loss or degraded performance. For longer data transmission, consider using PoE extenders or repeaters.
Q6: Do PoE splitters require external power sources?
A: PoE splitters are designed to derive power from the PoE switch or PoE injector, and they typically don’t require external power sources.
