Struggling with network connections over long distances? If you’re setting up IP cameras, wireless access points, or other devices in large areas, the limitations of your Ethernet cables can quickly become an issue. Ethernet cables have a maximum range of 100 meters (328 feet). After that, signals weaken, and your devices won’t work effectively. That’s where PoE ethernet extenders come in.
A PoE (Power over Ethernet) extender allows you to push data and power over a single Ethernet cable beyond that 100-meter limit. If you need to extend your network, a PoE extender is a simple, cost-effective solution. Let’s take a closer look at how PoE extenders work and where they can help you most.
How Does a PoE Extender Work?
PoE extenders take the original PoE signal and regenerate it. This extra boost, sent over an Ethernet cable, can be the extra strength you need to connect your PoE-enabled device. Whether it’s a wireless access point, VoIP phone, or IP camera, a PoE extender pushes the signal further than the standard 100 meters.
Specific devices, such as the NV-320SE or NV-30SEKIT, extend the Ethernet connection beyond this limitation while simultaneously providing PoE power. This is achieved through a dual Power over Ethernet-injected 10/100/1000 Mbps Ethernet port. However, an NV-320SE has a 56V DC power source (which should be included with your purchase).
PoE Extender vs. PoE Injector: What’s the Difference?
If you’re new to PoE setups, it’s easy to confuse PoE extenders with PoE injectors. Although both play essential roles, they have different purposes.
A PoE injector is used when your device doesn’t natively support PoE. It injects power into the Ethernet cable, allowing non-PoE devices like older IP cameras or phones to work over a single cable. It’s essentially a power source for your non-PoE devices.
A PoE extender is different. It doesn’t add power to the cable. Instead, it regenerates both power and data signals so that they can travel farther distances so you can connect your devices well beyond the 100-meter limit of an Ethernet cable.
While PoE injectors are for powering non-PoE devices, PoE extenders are for extending the range of any PoE-enabled device. You’ll likely need a PoE extender if you’re working with devices far from the central network switch.
How Far Can the PoE Connection Extend?
By now, you’re probably wondering just how far a PoE extender can take your network. The answer depends on the type of extender you use. Let’s look at the NV-320SE as an example.
The NV-320SE is powerful enough to extend an Ethernet connection up to 3 km. It uses a single twister-pair of network or phone-grade cable and is installed with the NV-202G. Together, this is classified as the NV-320SEKIT.
Installation of the NV-202G occurs at the origination point, connected to a router or switch. The NV-320SE is installed at the remote site alongside the PoE devices. The NV-320SE requires a separate power source, which then provides data and power to the connected PoE devices. With the NV-320SE’s Ethernet ports, you receive 30W each, regardless of the distance between the NV-320SE and the NV-202G.
Types of PoE Extenders
There are different types of PoE extenders, and choosing the right one depends on your network needs.
Single-Port vs. Multi-Port PoE Extenders
A single-port PoE extender has one input port and one output port, which can extend power and data to a single device. This type is perfect for small setups, such as powering a single security camera or wireless access point.
However, a multi-port PoE extender is more efficient if you need to connect various devices. Multi-port extenders have several output ports, allowing you to connect multiple devices simultaneously. These are commonly used in larger setups, such as surveillance systems with multiple cameras or commercial buildings with several wireless access points.
The NV-320SE is unique in that it has two Ethernet ports that provide 30W each. It also contains one line port connected to the NV-202G at the origination site.
How to Extend PoE with an Active PoE Extender
An active PoE extender uses an external power source to magnify the signal. This feature makes active extenders ideal for long distances and devices that require more power, like high-definition cameras or advanced access points.
To extend PoE using an active extender, follow these steps:
- Connect the PoE source (PoE switch or injector) to the IN port of the extender.
- Connect the PoE-powered device (like an IP camera) to the OUT port.
- Plug the extender into a power outlet using the provided PoE ethernet adapter.
This setup ensures reliable power and data transmission, even over long distances.
How to Extend PoE with a Passive PoE Extender
A passive PoE extender doesn’t need an external power source. It draws power from the Ethernet cable itself, which makes it easier to install. However, passive extenders don’t boost the signal like active ones do, so they’re best for shorter distances and low-power devices.
To set up a passive PoE extender, connect the PoE source to one end of the Ethernet cable. Then, insert the passive PoE extender between the source and the powered device. Passive extenders are a good choice for simpler setups where cost is a concern, but they may not be suitable for high-powered devices or long distances.
Common Use Cases for PoE Extenders
PoE extenders are incredibly versatile. They solve many challenges in networking, especially where running separate power lines is impractical or expensive. Here are some of the most common applications for PoE extenders.
Security Systems
One of the most popular uses for PoE extenders is in security systems. When setting up IP cameras to monitor large areas, like parking lots, warehouses, or stadiums, you often need to place the cameras far from the network switch. PoE extenders allow you to power and connect these cameras without the need for extra power lines, ensuring reliable surveillance over long distances.
Using multiple PoE extenders, you can set up a comprehensive security network, no matter how far apart the cameras are. This benefit makes them ideal for large-scale security installations where coverage is critical.
Wireless Access Points
Providing Wi-Fi access in large buildings or outdoor spaces often requires wireless access points placed far from the network source. PoE extenders allow you to power these access points and keep them connected, even when they’re hundreds of meters away from the nearest switch. They’re handy for campuses, hotels, or even large office buildings where internet access is essential.
Industrial and Commercial Environments
Factories, warehouses, and other industrial settings often require networking equipment far from the central hub. Installing power lines in these environments can be costly and time-consuming. Stop worrying about extra power cables — PoE extenders let you connect and power devices like industrial sensors, wireless access points, and security cameras with a single cable.
Cables have a way of multiplying, don't they? But what if you could string together a seamless network across an entire office building or shopping mall without the mess? That's precisely what PoE extenders deliver - cleaner, more cost-effective networking.
Choosing the Right PoE Extender for Your Needs
With so many options on the market, how do you choose the proper PoE extender for your setup? Here are a few factors to consider when selecting the best option for your network:
- Distance Requirements: Consider how far you need to extend your network. A single-port PoE extender might be enough if it’s only a small distance. However, if you need to extend your network over a large area, you might need multiple extenders or a multi-port option to keep everything connected.
- Power Needs: Some devices, like high-definition cameras or advanced wireless access points, require more power to operate. If your devices need more power than a passive extender can provide, you may need to opt for an active PoE extender to ensure a stable connection.
- Environmental Factors: Are you installing the extender indoors or outdoors? If you’re working in a harsh environment or setting up outdoor security systems, look for PoE extenders that are weatherproof and durable enough to handle extreme conditions.
- Port Requirements: Do you need to power and connect just one device, or do you have several devices in the same area? For larger setups, a multi-port PoE extender is the most efficient option.
By taking these factors into account, you can select the suitable PoE extender for your specific needs. Having the right network extension device will ensure a reliable and seamless network.
