Technical Architecture & Functionality
Newnex FireNEX™-80G is a modular USB 3.2 extension system over fiber built for environments where you need multiple high-speed USB devices far from the host PC without the usual copper limitations and EMI headaches.
How the system works
- One Local Unit installs in the host computer via PCIe Gen3 x8 and provides up to four fiber links.
- It pairs with up to four Remote Units, each Remote providing two USB-A ports supporting up to USB 3.2 Gen 2 (10Gbps) per port.
- With all four remotes installed, the system can run up to eight USB 10Gbps devices simultaneously, with up to 80Gbps total system bandwidth (aggregate across remotes).
Distance depends on USB speed (important)
Maximum extension range varies by negotiated USB speed:
- USB 3.2 Gen 2 (10Gbps): up to 300m (980 ft)
- USB 3.2 Gen 1 (5Gbps): up to 700m (2,300 ft)
Designed for industrial reliability
Remote Units use metal enclosures, include mounting provisions, and feature USB3 Vision compliant screw-locking ports for more reliable cabling in industrial and machine vision deployments.
Operational note (don’t skip this)
This is a system-style extender, not a casual dongle. After initial setup, disconnecting fiber or powering off a remote unit may require rebooting the host PC. Plan your installation accordingly.
Key Engineering Advantages
Build a System, Not a Single Link
Start with one remote and expand up to four remotes as your device count grows.
Long Distance with Real Throughput
Support up to 700m at 5Gbps or 300m at 10Gbps depending on device speed negotiation.
Eight Devices, One Host PC
With four remotes, run up to eight USB 10Gbps devices simultaneously with high aggregate bandwidth.
Industrial-Grade Reliability
Metal housings, mounting provisions, and locking ports reduce downtime from vibration and cable stress.
EMI Immunity Over Fiber
Fiber transport helps avoid interference issues that break long copper USB runs in industrial spaces.
Legacy-Friendly
Backward compatible with USB 2.0/1.1 devices for mixed-speed deployments.
