USB 2.0 optical extender for remote peripherals

This UTEK adapter pair extends USB 2.0 signals up to 100 metres over CAT6 cable or 20 kilometres over single-mode fibre, letting you place webcams or other low-speed devices far from the host computer. The compact transmitter and receiver units work together without any software configuration, making them suited for industrial, medical or studio installations where the host must stay in a secure or climate-controlled room.

Sustained signal integrity over long links

During continuous operation the extender maintains stable USB 2.0 data rates by limiting low-speed traffic to one byte per second, preventing buffer overflows on extended cable runs. A yellow connection LED on each unit flashes slowly while the link is healthy, giving immediate visual confirmation that the 100-metre copper or 20-kilometre fibre path remains error-free under load.

Plug-and-play pairing with minimal pitfalls

Installation consists of connecting the local unit to the PC, the remote unit to the peripheral, and linking them with a single CAT6 patch cord or FC-terminated fibre; no drivers or DIP switches are required. The most common issue is using sub-standard patch cables that do not meet the IEEE 568B wiring scheme, which causes the link LED to stay dark and the USB device to remain unrecognised.

Questions about this item

Does the 4-port USB 2.0 extender generate noticeable heat when running continuously over 20 km fiber?

The compact paired units have no active cooling and draw minimal power from the host USB bus, so they stay cool during all-day operation.

What cables and power sources must I already have to use the 100 m CAT6 RJ45 link?

You need a standard CAT-5E/6 patch cable wired to the IEEE-568B pinout and a free USB-A port on the computer; the kit includes a US-plug power adapter for the remote unit.

Will my older USB 1.1 webcam work through the 2.0 optical extension without extra drivers?

Yes, the extender transparently passes low-speed, full-speed and high-speed USB 2.0 traffic, so legacy USB 1.1 cameras function normally.
