DVI KVM USB Extender Over Fiber 4K@30Hz EMI Immunity Up to 20km (12.4 Miles), Remote Keyboard & Mouse, EDID, RS232, IR, Zero Latency
- Up to 20km (12.4 miles) over a single LC singlemode fiber cable. Unlike copper extenders, our fiber solution maintains pure 4K video and USB 2.0 signals with zero degradation, no electromagnetic interference, and virtually no latency perfect for campuses, data centers, and industrial sites
- It is plugandplay no drivers, no software, no network configuration. The transmitter and receiver autopair as soon as they are powered on. Works with Windows, macOS, Linux, and any other OS that supports standard USB and DVI
- You can connect a keyboard, mouse, USB flash drive, printer, touchscreen, camera, or card reader. The extender transparently passes USB signals from your local console to the remote computer as if they were plugged in directly. All 4 ports are USB 2.0 (up to 480 Mbps)
- It transmits audio via the DVI channel (if your source supports DVI audio) or a dedicated 3.5mm jack. It also includes RS232 and IR passthrough for controlling industrial equipment, PTZ cameras, project

Ordinary KVM extenders (Cat5e/6/7) are limited to 50400 ft, suffer from EMI, often support only USB 1.1 (keyboard/mouse only), and can be unreliable over longer runs. Our fiber solution gives you 20 km stable connection, zero EMI, true USB 2.0 for peripherals
Why DVI instead of HDMI? Supports HDCP?
Yes, HDCP 1.2 works with protected content. DVI offers screwlocked connection, no CEC/ARC interference, and avoids forced higher HDCP versions. Use a passive DVItoHDMI cable for HDMI displays. Audio via 3.5mm jack.
Does this work over the internet?
No. It requires a direct fiber cable between transmitter and receiver no Ethernet, WiFi, or IP network. This gives zero latency, complete airgap security, and no dependency on network infrastructure.
What video resolutions are supported?
4K@30Hz (3840×2160) and 1080p@60Hz via DVI. Backward compatible with lower resolutions. For 4K 60Hz at short range, look at copper options; this maintains 4K across 20km.
Is there noticeable video lag?
No. Fiber latency is microseconds; total endtoend delay <1ms imperceptible. Perfect for realtime applications like video editing, gaming (1080p), and medical imaging.
