It sounds like you're describing a USB to RJ45 extender, specifically designed to extend USB signals over long distances using Ethernet (RJ45) cables. Here are some details about it:

• Functionality: Allows you to extend USB signals over long distances using Ethernet (RJ45) cables.
• Connectors: USB (typically USB Type-A) male connector on one end and RJ45 (Ethernet) female connector on the other end.
• Range: Extends USB signals up to 50 meters (approximately 164 feet) using Ethernet cables.
• Compatibility: Works with various USB devices such as printers, scanners, webcams, keyboards, mice, or USB storage devices.
• Power: Some extenders may require external power for proper operation, especially over longer distances.
• Data Transfer: Supports high-speed data transfer rates depending on the USB version (e.g., USB 2.0, USB 3.0).
• Plug-and-Play: Typically supports plug-and-play functionality, requiring no additional drivers or software installation.
• Construction: Constructed with high-quality materials for durability and reliability.
• Usage: Useful for situations where you need to extend USB signals over long distances, such as in industrial environments, offices, or home setups where USB devices need to be located far from the host computer.
