UGREEN US121 USB 2.0 Male to USB A Female Active Extension Cable with Chipset 25M

In-depth Details

1. Cable Design and Build

• Length: A generous 25-meter length allows for extended reach between devices, ideal for setups that require distance such as conference rooms, security systems, or data centers.

• Material: High-quality PVC jacket ensures durability and flexibility. Gold-plated connectors resist corrosion and improve signal quality.

2. USB 2.0 with Active Signal Boosting

• Speed: Supports full-speed USB 2.0 data transfer at up to 480 Mbps.

• Active Chipset: The integrated chipset actively regenerates and amplifies the signal across the long distance, preventing data loss or degradation. This makes it suitable for maintaining stable performance over 25 meters—a distance at which passive cables would fail.

3. External Power Support

• Micro USB Port: Includes a Micro USB port for connecting a 5V external power supply (power adapter not included). This is especially useful for high-power-draw devices or when using multiple peripherals through a USB hub.

• Power Efficiency: While most low-power devices (like mice or keyboards) work without extra power, devices such as external hard drives or HD webcams may need it.

4. Compatibility

• Wide Support: Fully compatible with USB-enabled devices such as:

  • Printers and scanners

  • USB hubs

  • Cameras and webcams

  • External drives (USB flash, HDDs)

  • Game controllers and USB microphones

• OS Compatibility: No drivers needed. Works with Windows (XP and later), macOS, and Linux.

5. Use Cases

• Security Systems: Useful for extending USB surveillance cameras without signal loss.

• Professional AV and Conference Setups: Suitable for high-quality video/audio streaming gear that requires long-distance signal transmission.

• Industrial and Commercial Environments: Durable build supports continuous use in demanding environments such as server rooms or POS systems.

6. Limitations

• USB 2.0 Only: Does not support USB 3.0 or 3.1 speeds. Devices will downgrade to USB 2.0 performance.

• Power-Intensive Devices: May require a powered USB hub or external power if devices draw more current than the cable can supply over long distances.

If you need a cable to transmit USB signals reliably over long distances without degradation, especially in professional or industrial environments, the UGREEN US121 25M active extension cable is purpose-built for that role.
