20 km 4K HDMI Fiber KVM Extender Kit

This transceiver kit extends HDMI video, audio and USB keyboard-and-mouse control up to 20 kilometres over a single LC fibre link. It targets installers and operators who need to place a source such as a PC, PS4 or PS5 far from the display while keeping full KVM interaction.

Build integration with LC fibre and loop output

The transmitter and receiver each require the supplied 12 V/1 A power adapter and connect via one LC single-mode or multi-mode fibre strand. A local HDMI loop output on the transmitter lets a nearby monitor stay active, and bi-directional IR passthrough carries remote-control signals back to the source.

Upgrade from copper HDMI or basic extenders

Copper cables and short-range extenders cannot reach 20 km or carry uncompressed 4K at 60 Hz without signal degradation. This kit replaces them when distance, zero-latency KVM control and HDCP 2.2 compliance are required for professional AV, security or broadcast workflows.

Questions about this item

Does the 10Gbps link ever saturate when I push 4K@60Hz video plus USB KVM traffic all day?

The extender runs at a fixed 10Gbps rate and the spec lists uncompressed 4K@60Hz with no loss or delay, so the bandwidth ceiling is built into the design.

How much heat or fan noise should I expect from the transmitter and receiver during continuous operation?

The units are powered by 12V/1A adapters with no fan mentioned, so they run silently and generate only modest warmth typical of low-power fiber transceivers.

What fiber cable and connectors must I already have to complete the 20km link?

You need a single-mode or multi-mode LC fiber optic cable up to 20km; the kit includes two LC SFP modules but the fiber itself is not supplied.
