The UGREEN US121 30M USB 2.0 Active Extension Cable is designed for users who need long-distance USB connectivity without sacrificing stability or performance. Featuring an integrated signal repeater chipset, it maintains a strong, clear signal over the full 30-meter length—ideal for professional, industrial, and home use.
This cable is perfect for setups such as security camera installations, conference systems, printer extensions, and AV control systems, where a reliable long-range USB connection is essential.
Ordinary passive USB cables lose signal integrity beyond 5 meters. The UGREEN US121 30M overcomes this limitation with an embedded active chipset that amplifies and regenerates the USB signal in real time.
This ensures zero signal loss, minimal latency, and uninterrupted data transmission across the entire 30-meter length—making it ideal for mission-critical applications such as webcam streaming, audio capture, and industrial device control.
Despite its long reach, the cable maintains data transfer speeds up to 480 Mbps, meeting USB 2.0 specifications. This makes it suitable for most USB peripherals that don’t require the bandwidth of USB 3.0.
Compatible devices include:
Webcams and CCTV cameras
Printers and scanners
External hard drives (USB 2.0)
Audio interfaces and microphones
Keyboards, mice, and controllers
It’s also backward compatible with USB 1.1 devices, ensuring wide usability across both new and legacy systems.
The cable includes a DC 5V Micro USB port that allows for an optional external power adapter connection.
This feature is particularly useful when connecting high-power-draw devices such as:
External hard drives
Multiple USB peripherals via a hub
HD webcams or cameras used for live streaming
When external power is connected, the cable ensures consistent current delivery, preventing disconnections or unstable operation caused by voltage drop across the 30-meter span.
The UGREEN US121 30M cable is engineered to deliver long-lasting performance under demanding conditions:
Gold-plated connectors resist corrosion and improve conductivity
Heavy-duty PVC jacket offers flexibility and protection against wear
Reinforced strain relief reduces stress at the connector ends
Shielded cable design minimizes electromagnetic interference (EMI) and signal noise
This robust construction makes it ideal for continuous operation in industrial, office, and home environments.
The UGREEN US121 30M requires no additional drivers or configuration. Simply connect it between your host device and peripheral, and it’s ready to use.
Supported operating systems:
Windows (XP / 7 / 8 / 10 / 11)
macOS
Linux
It works seamlessly with PCs, laptops, smart TVs, gaming consoles, and USB hubs, making it one of the most versatile active USB extension cables available.
The UGREEN US121 30M Active Extension Cable is perfect for:
Security and surveillance systems – Extending USB cameras or CCTV connections
Conference and AV setups – Connecting microphones, webcams, or control panels in meeting rooms
Education and presentations – Linking smartboards, projectors, or interactive displays
Industrial environments – Connecting USB devices to control systems across large spaces
Retail or POS systems – Reliable connectivity for scanners, printers, and terminals
USB 2.0 only: Does not support USB 3.0 or 3.1 speeds; maximum data rate is 480 Mbps.
Power-intensive devices: May require external 5V power or a powered USB hub for stable operation.
Does this 30M cable cause any lag or signal delay?
No. The active repeater chipset continuously amplifies and stabilizes the signal, ensuring low latency and consistent performance.
Can I use this cable for USB webcams or security cameras?
Yes. It’s ideal for webcam extensions in surveillance or conferencing setups, maintaining clear video transmission even over 30 meters.
Do I need to connect external power?
Only if your connected device draws high power (like external hard drives or multi-port hubs). Low-power devices work without it.
Can I use multiple 30M cables in series?
It’s not recommended to daisy-chain multiple active cables. For best performance, use a single 30M active cable.
Is it compatible with USB 3.0 devices?
Yes, it will connect with USB 3.0 peripherals but at USB 2.0 speeds (up to 480 Mbps).
