2. Key Features
- High-Speed Performance: Supports up to 40 Gbps data transfer and 2000 MHz bandwidth, ideal for demanding network tasks.
- Enhanced Anti-interference: Features 4 shielded foiled twisted pairs (F/FTP), a pure copper core, and gold-plated RJ45 connectors to minimize interference and ensure stable network speed.
- Durable Construction: Wrapped with a quality cotton braided cord for increased strength and durability, tested to withstand over 10,000 bends.
- Power over Ethernet (PoE) Support: Compatible with PoE power supply functions (except for the 65ft length), eliminating the need for additional power supplies for PoE devices.
- Wide Compatibility: Equipped with standard RJ45 connectors, compatible with computers, laptops, modems, routers, gaming consoles (PS5, Xbox), and other networking devices. Backward compatible with Cat7, Cat6e, Cat6, Cat5e, and Cat5 standards.

3. Setup Instructions
Connecting your UGREEN Cat 8 Ethernet Cable is a straightforward process. Follow these steps for a secure and reliable connection:
- Unpack the Cable: Carefully remove the Ethernet cable from its packaging. Ensure both RJ45 connectors are free from any protective caps.
- Identify Ports: Locate the Ethernet (RJ45) port on your network device (e.g., router, modem, switch) and the device you wish to connect (e.g., computer, laptop, gaming console, smart TV).
- Connect First End: Insert one end of the UGREEN Cat 8 Ethernet Cable into the Ethernet port of your network device. Ensure it clicks securely into place.
- Connect Second End: Insert the other end of the cable into the Ethernet port of your target device. Again, ensure a secure click.
- Verify Connection: Most devices will automatically detect the Ethernet connection. Look for a blinking or solid LED indicator light near the Ethernet port on both devices, indicating an active network link.

4. Operating Instructions
The UGREEN Cat 8 Ethernet Cable is designed for plug-and-play operation. Once connected, your devices should automatically establish a network connection.
- Automatic Detection: Modern operating systems and network devices typically detect the Ethernet connection automatically. No additional drivers or software are usually required.
- Network Configuration: If your network requires specific IP address settings or other configurations, please refer to your device's operating system or network device manual.
- Optimal Performance: For the best performance, ensure your network devices (router, modem, network card) also support Cat 8 or higher speeds. While backward compatible, maximum speeds are achieved with compatible hardware.

5. Maintenance
To ensure the longevity and continued high performance of your UGREEN Cat 8 Ethernet Cable, consider the following maintenance tips:
- Avoid Sharp Bends: While the braided design offers flexibility, extreme or sharp bends can damage the internal wires. Route the cable with gentle curves.
- Protect Connectors: The RJ45 connectors are robust but can be damaged by excessive force or impact. Use the provided protective caps when the cable is not in use or being stored.
- Keep Clean: Periodically wipe the cable and connectors with a dry, soft cloth to remove dust and debris. Avoid using harsh chemicals.
- Secure Connections: Ensure the cable is securely plugged into ports to prevent accidental disconnections, which can lead to signal loss or damage to the connector latch.

6. Troubleshooting and Optimal Performance
If you experience issues with your network connection or wish to optimize performance, consider the following:
- No Network Connection:
- Ensure both ends of the Ethernet cable are securely plugged into their respective ports.
- Check the LED indicators on your network devices and computer for activity.
- Restart your modem and router.
- Test with a different Ethernet port or device to isolate the issue.
- Slow Internet Speed:
- Verify that your internet service provider (ISP) is delivering the expected speeds.
- Ensure all devices in your network chain (modem, router, network adapter) support the desired speeds (e.g., 10 Gigabit Ethernet for full Cat 8 utilization).
- Minimize other network activity during speed tests.
- Consider the length of your cable; while Cat 8 supports long distances, shorter runs can sometimes offer slightly better performance in specific scenarios.
- Intermittent Connection:
- Check for physical damage to the cable or connectors.
- Ensure the cable is not running near strong electromagnetic interference sources.
