The UGREEN US121 25M USB 2.0 Active Extension Cable is the ultimate solution for users who need to extend USB connections over exceptionally long distances without signal loss. Designed with a built-in signal amplification chipset, it ensures stable and reliable data transfer speeds of up to 480 Mbps, even across 25 meters.
Perfect for professional, industrial, and commercial setups, this active cable is ideal for security systems, conference rooms, data centers, and classrooms—anywhere you need dependable USB connectivity far from your host device.
Unlike standard USB cables that lose signal integrity beyond 5 meters, the UGREEN US121 25M includes an active repeater chipset that amplifies and regenerates the USB signal. This ensures consistent, uninterrupted communication between your devices even at extended ranges.
The chipset, located near the USB-A female end, is specifically engineered to minimize latency, reduce data loss, and maintain stable transmission—ideal for webcams, audio interfaces, or USB microphones used in real-time environments.
Compliant with the USB 2.0 standard, the cable supports transfer speeds of up to 480 Mbps, making it suitable for a wide range of peripherals. While not designed for USB 3.0-level bandwidth, it performs exceptionally well for devices like:
Printers and scanners
Cameras and webcams
External hard drives (USB 2.0)
USB microphones and headsets
Keyboards, mice, and controllers
The cable is also backward compatible with USB 1.1 devices, ensuring broad flexibility across legacy and modern setups.
To support power-hungry peripherals, the UGREEN US121 25M features a Micro USB port that allows external 5V DC power input (adapter not included).
This is especially beneficial when using:
External hard drives
High-resolution webcams
Multi-port USB hubs
When connected, the external power ensures your devices receive consistent current, eliminating disconnections or unstable operation caused by voltage drop over long distances.
UGREEN designed the US121 25M to endure demanding environments. Key construction features include:
Gold-plated connectors for corrosion resistance and optimal conductivity
Thick PVC jacket offering flexibility, tangle resistance, and wear protection
Molded strain relief to prevent bending or breaking near the connectors
Multi-layer shielding to minimize electromagnetic interference (EMI) and crosstalk
The result is a durable, stable, and interference-free data connection that performs consistently even with continuous use.
The UGREEN US121 25M requires no drivers or software installation—simply plug it in and start using it immediately. It’s compatible with:
Windows (XP / 7 / 8 / 10 / 11)
macOS
Linux
It works seamlessly with laptops, desktop PCs, smart TVs, gaming consoles, and USB hubs.
This cable is purpose-built for scenarios requiring long, stable USB connections, such as:
Security systems – Extend CCTV or webcam connections without loss
Conference setups – Connect microphones, cameras, or control panels in boardrooms
Classroom and training setups – Link interactive displays or projectors
Data centers – Extend connectivity for USB peripherals to server racks
Point of Sale (POS) systems – Provide reliable USB links in retail environments
USB 2.0 only: Does not support USB 3.0 or 3.1 speeds; devices will operate at 480 Mbps maximum.
Power-intensive devices: May require a powered hub or 5V adapter for optimal performance.
Does this 25M cable lose signal over long distances?
No. It features a built-in active chipset that amplifies and stabilizes the signal, maintaining reliable data transfer over the full 25 meters.
Can I use this for a webcam or camera setup?
Yes, it’s perfect for webcams, conference cameras, and other video devices that need long-distance connections without lag or dropouts.
Do I need an external power supply?
Only if your connected device requires higher power (e.g., external hard drives or powered USB hubs). For low-power devices like mice or printers, it works fine without additional power.
Can I connect multiple active cables together?
While possible, daisy-chaining multiple active cables may cause instability. For best performance, use a single 25M active cable.
Is it compatible with USB 3.0 devices?
Yes, it will work with USB 3.0 or 3.1 devices but will transfer data at USB 2.0 speeds (up to 480 Mbps).
