USB Extender over Fiber

Newnex USB fiber extenders are designed to extend high-performance USB signals over long distances, supporting USB 3.0 and USB 3.2 data transmission from 5Gbps up to 20Gbps.

Using fiber optic cable, these extenders enable USB connectivity up to 700 meters while delivering excellent EMI immunity and stable signal performance. They are also fully backward compatible with USB 2.0 and USB 1.1 devices, providing broader device support than many competing solutions.

Frequently Asked Questions

How far can a USB extender over fiber reach? Newnex USB fiber extenders can reach from 650 ft (200 m) to 2,300 ft (700 m), depending on the model and data rate. USB 3.2 Gen 1 (5 Gbps) models can reach up to 2,300 ft (700 m), while higher-speed 10 Gbps and 20 Gbps models typically support shorter distances.
What fiber optic cable do I need? Most Newnex fiber extender models use OS2 single-mode fiber with duplex LC-LC connectors, while certain models such as the FireNEX-5000H+ require OM3 or OM4 multimode fiber. Always check the extender specification before selecting the fiber cable, since single-mode and multimode fiber are not interchangeable.
When should I choose a USB fiber extender? A fiber extender is ideal for long-distance USB extension and electrically noisy environments, because it is immune to EMI. It also provides galvanic isolation between the host and remote equipment, and can extend USB far beyond the distance supported by CAT or active copper solutions.
Does a fiber USB extender need power at both ends? Not always. The remote unit requires external power because fiber does not carry electrical power, while some Newnex local units are bus-powered from the host. Power requirements vary by model, so check the product specifications for the required DC input.
How many devices can I connect at the remote end? Newnex fiber extenders are available with one to four downstream USB ports. If more ports are needed, a USB hub can be connected to the remote unit for expansion. Keep in mind that all connected devices share the same upstream USB bandwidth, so total throughput should be considered when using multiple devices.
Are fiber extenders backward compatible with USB 2.0? It depends on the model. Most Newnex USB fiber extenders support USB 2.0 and USB 1.1 devices across all operating systems, but compatibility can vary by extender and operating system. Check the product specifications when legacy USB support is required.
