USB 2.0 Optical Extension Adapter

This USB 2.0 optical extension adapter extends USB signals up to 100m over CAT6 cable or 20km over FC fiber. The kit includes a paired transmitter and receiver with four USB ports for webcams and other peripherals. It operates without software configuration and ships with a US plug power supply. The compact design suits remote PC access in industrial or studio settings.

Plug-and-play pair installation

Connect the local unit to the host PC and the remote unit to the USB devices, then link them with a single CAT6 or fiber cable. The adapter follows the IEEE-568B wiring standard for network cable. A yellow Conn LED flashes slowly when the link is active. No driver installation is required, but the link will not pass USB 3.0 or higher traffic.

Stable long-distance operation

The extender maintains low-speed and full-speed USB 2.0 data rates over the full 100m or 20km distance. Low-speed control channels are limited to one byte per second to preserve link integrity. The hardware also supports remote host power on, off and restart commands. High-speed USB 2.0 throughput is sustained without the latency spikes seen in short-range wireless alternatives.

Questions about this item

How do I confirm the 4-port USB 2.0 extender is working after connecting the FC fiber or CAT6 RJ45 cable?

The yellow Conn LED on each unit flashes slowly when the transmitter and receiver are linked correctly over the 100 m network cable or 20 km fiber, showing the USB 2.0 signal path is active.

What comes in the box and what must I supply separately?

The package includes one transmitter and one receiver, each with four USB 2.0 ports and a US-plug power adapter; you provide the CAT5e/6 patch cable (up to 100 m) or single-mode FC fiber (up to 20 km) to link them.

Should I choose the CAT6 RJ45 or the FC fiber version for my 4-port USB 2.0 extension?

Both interfaces are on the same pair — use CAT6 RJ45 for runs up to 100 m or FC fiber for runs up to 20 km; select the cable type that matches your distance requirement.
