In today's highly digitalized office, security, education, and industrial environments, USB devices are everywhere—from keyboards, mice, and flash drives to webcams, printers, and AV equipment. USB ports are the essential bridge for connection and communication. However, traditional USB cables are limited by distance and often suffer from signal loss or even failure to connect over long runs. That’s where the POE USB extender comes in—providing a stable and efficient solution for long-distance USB transmission.
What is a POE USB Extender?
A POE USB extender is a device that transmits USB signals over long distances using CAT6 Ethernet cables. With built-in POE (Power Over Ethernet) support, it eliminates the need for a separate power supply at the receiver end. It’s plug-and-play, compatible with major systems like Windows, Mac, and Linux, and offers quick and flexible installation.
Let’s take the 100m POE USB Extender eKL-HUA as an example. The transmitter connects to your PC via USB and plugs into a power adapter. It sends signals through a CAT6 cable to the receiver, which doesn’t need additional power—just plug in the cable and it works. The receiver features four USB ports plus 3.5mm headphone output and mic input, enabling both data and audio transmission over distance.

Application Scenarios
01. Video conferencing and remote teaching
In conference rooms and classrooms, it's common to place cameras and microphones far from the computer. POE USB extenders solve the cable length issue and support synchronized AV transmission.
02. Security monitoring systems
Many USB cameras are used in temporary surveillance setups or indoor monitoring. The extender allows flexible deployment without being limited by power or distance.
03. Industrial control and server room management
Allows operators to connect remote terminals to main control units from a safe distance, improving both safety and management efficiency.
04. Medical imaging systems
Stable USB transmission makes it ideal for medical-grade equipment like ultrasound or image capture devices that require high data integrity.
Why Choose a POE USB Extender?
As USB devices are widely used in smart offices, remote monitoring, and industrial automation, achieving stable long-distance connections has become a critical design challenge. A POE USB extender delivers both power and data over one cable—simplifying wiring and boosting flexibility.
These devices are already being used in real-world projects like smart classrooms, hospital imaging terminals, industrial control panels, and corporate meeting rooms. With features like multi-port expansion, audio support, and driver-free setup, they make system deployment easier and future maintenance more efficient.
For projects involving complex wiring, long-distance operation, or multi-device setups, POE USB extenders offer a clean, stable, and professional solution.
