How to Extend PoE Distance Beyond 100 Meters (Without Losing Power or Speed)

When installing IP cameras, Wi-Fi access points, or other PoE devices, you might hit a frustrating limit: Ethernet cables can only carry power and data up to 100 meters.

So what if your camera is on a tall pole, a parking lot corner, or across a warehouse? That’s where the PoE extender comes in — a small but powerful device that extends your PoE signal far beyond the standard range.

Why PoE Has a 100-Meter Limit

Traditional Ethernet cables (Cat5e/Cat6) carry both power and data through copper wires. However, after about 100 meters (328 ft), signal loss and voltage drop become significant. Beyond that distance, the device may not receive enough power, or data speed may drop.

That’s a big problem for outdoor installations, where devices are often far from the power source.

What Is a PoE Extender?

A PoE extender is a plug-and-play device that repeats both data and power along the same cable — essentially acting as a booster for PoE signals.

Think of it as a relay runner in a race: it picks up the energy from one cable and carries it forward for another 100 meters.

• Input: IEEE 802.3af/at (PoE or PoE+)
• Output: Up to 30W per port
• Extended distance: +100 meters per unit
• Data speed: Gigabit (1000 Mbps)

How It Works

1. Connect your PoE switch or injector to the extender’s input port.
2. The extender regenerates power and data.
3. Connect your PoE device (like a camera or AP) to the extender’s output port.
4. Enjoy another 100 meters of stable PoE transmission — with no power outlet needed in between.

You can even cascade multiple extenders (2 or 3 in a row) to cover up to 300 meters, depending on power requirements.

Why Use an Outdoor Gigabit PoE Extender

An outdoor PoE extender by YuanLey is designed for harsh environments and professional setups:

• Weatherproof housing (IP65/IP67): works in rain, snow, or heat
• Surge protection: shields your network from lightning or power spikes
• Wide operating temperature: from -20°C to +60°C
• Gigabit throughput: ensures no speed loss even over long distances

Perfect for:

• IP cameras on parking poles
• Outdoor Wi-Fi access points
• Smart streetlights or IoT systems
• Long-range industrial connections

Installation Tips

• Use Cat6 or better cables for Gigabit performance.
• Keep all connections weather-sealed.
• For high-power devices (like PTZ cameras), use PoE+ (802.3at) input.
• Avoid chaining too many extenders — 2 to 3 units are ideal.

Conclusion

Extending your PoE network doesn’t have to be complicated. With an Outdoor Gigabit PoE Extender, you can easily push power and data far beyond 100 meters — no extra outlets, no signal loss.

If you’re planning to install IP cameras or Wi-Fi devices outdoors, this small tool can make your setup cleaner, safer, and much more reliable.
