The Thor Fiber USB Fiber Optic Transmission System is a professional USB over fiber extender kit designed to extend USB devices over long distances using fiber optic cable. This system is ideal for applications where standard USB copper cable is too short, where electrical noise is a concern, or where USB devices need to be located far away from the computer, workstation, server, control room, headend, or operator station.
This product family is available in different model versions depending on the required USB speed. Please note that USB speed support is model dependent. It is important to select the correct model based on the USB devices being used.
The F-4USB-TX/RX-SFP model supports USB 1.1 and USB 2.0 devices. This model does not support USB 3.0 devices.
For USB 3.0 or USB 3.2 applications, please select the F-4USB-TX/RX-SFP-3.0 model. The USB 3.0 model is designed for USB 3.0 / USB 3.2 devices only and is not backward compatible with USB 1.1 or USB 2.0 devices.
The USB fiber optic extender kit includes a transmitter and receiver and extends USB devices over a single fiber connection using SFP optical modules with LC fiber connectors. The integrated four-port USB hub allows up to four USB devices to be connected without requiring an additional external USB hub.
This USB over fiber system is commonly used for USB cameras, keyboards, mice, printers, scanners, external drives, touchscreens, audio devices, control interfaces, industrial USB devices, and other USB peripherals. It is a plug-and-play hardware-based solution with no software drivers required, making it easy to install in professional AV, broadcast, government, medical, industrial, education, security, multimedia, and commercial presentation systems.
Using fiber optic cable instead of copper USB cable provides long-distance extension, electrical isolation, and improved resistance to electromagnetic interference. This makes the Thor USB Fiber Optic Transmission System a reliable solution for mission-critical installations where USB devices must operate over extended distances.

This model is bidirectional; however on one end you have 4 USB inputs (transmitter) and on the other end you have 1 USB output (receiver). This is essentially a USB extension, but instead of using copper, it is transmitted over fiber for longer distances. For example, you can connect a USB drive on the RX (receiver) side, and the PC can access and transfer data from the USB drive through the RX to the TX (transmitter) side
