Extron FOX T USB Extender Plus HID SM (part number 60-1526-12) — singlemode fiber optic USB transmitter with device-class filtering for secure rooms.

This is the host end of a matched HID transmitter and receiver pair. A single female USB type B jack takes the computer connection and the transmitter converts it into a 600 Mbps optical stream on two LC fibers at 1310 nm, good for spans as long as 30 km. What separates the HID version from the standard model is what it will accept: device class filtering narrows the permitted peripherals to HID devices and smart card readers, so a keyboard, mouse, card reader or hub connects normally while unapproved hardware such as a mass storage stick is refused.

Key Capabilities

• Device class filtering limits recognised peripherals to HID types and smart card readers
• Singlemode transmission distance of 30 km (18.64 miles) at a 600 Mbps data rate
• 1310 nm singlemode wavelength on two LC connectors, -5 dBm typical transmit power
• 13 dB maximum singlemode optical loss budget for margin on long spans
• Peripheral emulation keeps the host aware of the far-end device across the link
• 3.3 watts at the device, 4.4 watts including the external universal power supply

Where It Is Used

The HID restriction makes this the transmitter of choice for government and defence facilities, secure operations centres, financial trading floors, and hospital or laboratory workstations where an operator needs keyboard, mouse and card-reader access to a machine kept in a locked equipment room across the campus.
