120M KVM Extender

This extender kit transmits 4K HDMI video and KVM control over a single CAT6 cable up to 120 metres. It includes a transmitter, a receiver and two power adapters. The system is designed for users who need to operate a computer or console from a remote display and keyboard.

Replaces long HDMI runs

Standard HDMI cables lose signal integrity beyond short distances, while this extender maintains 4K quality at 60, 100 or 120 metres depending on cable grade. The jump is worth it when the source and the operator must be in separate rooms or racks. T-568B CAT6 wiring is required to reach the maximum range.

4K over CAT6 headroom

The kit comfortably handles 4K resolution across the full 120 metre span when installed with specified cabling. It runs out if lower-grade Cat5e is used or if the wiring standard is not followed, reducing the reliable distance to shorter tiers.

Questions about this item

What category cable and wiring standard are required for the 120 m link?

Use a T-568B wired CAT6 cable between the transmitter and receiver to reach the full 120 m distance.

How do I connect the transmitter, receiver and power for a working link?

Plug the HDMI source into the transmitter, run a T-568B CAT6 cable to the receiver, connect the display to the receiver, then attach both supplied power adapters.

Which parts may need replacement if the link degrades over time?

The CAT6 patch cable and the two power adapters are the field-replaceable items; the transmitter and receiver units have no user-serviceable components.
