Product Identity

The Jansicotek 4K@60Hz HDMI Extender Kit transmits uncompressed video, audio and USB KVM signals up to 20 km over a single LC single-mode or multi-mode fiber link. It targets installers and operators who need lossless 4K extension with local loop-out and remote keyboard-mouse control in broadcast, signage or industrial environments.

Thermals Noise Power

The transmitter and receiver each ship with a dedicated DC 12V/1A power adapter, so both endpoints draw power independently from a standard mains supply. No active cooling fans are mentioned in the specifications, indicating silent operation suitable for noise-sensitive control rooms or studio settings.

Upgrade Path

This kit replaces copper HDMI runs or lower-distance fiber extenders that cannot reach 20 km, lack KVM support or omit a local HDMI loop output. The jump is worth it when the installation requires true 4K@60Hz fidelity, bi-directional IR and USB-HID control across campus-scale distances without compression artefacts or added latency.

Questions about this item

How do I connect the transmitter and receiver over LC fiber and which step is often missed?

Connect one LC single-mode or multi-mode fiber between the two included SFP modules, plug each module into its unit, attach the two power adapters, then link source to transmitter HDMI IN and remote display to receiver HDMI OUT; the step often missed is inserting both SFP modules before powering on.

What maintenance will the fiber link need over time?

The LC connectors and SFP modules require only occasional cleaning with a lint-free wipe and isopropyl alcohol if dust builds up; the DC 12V/1A power adapters should be replaced if voltage drifts or the units become unstable.

What limit appears first during continuous 4K@60Hz operation?

The 10Gbps transfer rate and HDMI 2.0b/HDCP 2.2 compliance set the bandwidth ceiling, so sustained 4K@60Hz at 3840x2160 is the maximum supported signal before any degradation.
