Power Over Ethernet to USB-C From Far Away

USB-C is a great technology, offering ultra-fast data transfer rates close to 10Gbps and increased power delivery for charging laptops, monitors, and TVs. However, the power advantage of USB-C diminishes over longer cable lengths. According to the USB-C (USB 3) specification, optimal power and transfer rates are maintained only when the cable length is under two meters (about six feet).

Power over Ethernet (PoE) is a proven way to deliver both data and power over long distances via cable. PoE Texas has introduced a product that extends USB-C connections using this technology.

“As a standard, USB-C offers amazing speed and power delivery. Unfortunately, USB-C can only transmit power less than ten feet (three meters), and the cable infrastructure comes at a cost premium. Ethernet cable, nearly ubiquitous in modern construction, can transmit power and data up to 328 feet (100 meters). USB-C power and data transmitted over Power over Ethernet significantly lowers the cost of adopting USB-C by eliminating the need for new electrical infrastructure.”

Extending USB-C Connections with Power over Ethernet

Real-World Example of PoE USB-C in Use

A user has a workstation located about 30 feet away from the production unit it needs to communicate with. The production unit is a USB-C duplicator by Nexcopy. The workstation manager controls the data to be loaded onto USB-C flash drives, while the production manager physically connects and disconnects the USB sticks during the duplication process.

Because a standard USB-C cable cannot cover the required distance, the user can employ the USB-C Power over Ethernet solution to deliver both power and data effectively to the remote device.

• Conference Room Setup: A USB-C monitor is mounted 40 feet away from the docking station. Using PoE to USB-C allows both video data and charging power to reach the display over a single Ethernet cable.
• Security Camera Installation: A USB-C powered 4K security camera is installed 80 feet from the control room, receiving both power and data via PoE without additional electrical wiring.
• Point-of-Sale Terminal: Retail stores can power USB-C tablets located 50–75 feet from the main server rack using PoE, avoiding the need for extra outlets and USB hubs.
• Industrial Automation: A USB-C duplicator or machine placed 60 feet from the workstation uses PoE adapters to maintain stable power and high-speed data transfer without costly long USB cables.
