4K60 HDMI-over-Fiber Extender with USB KVM (10km)
Rack the Source, Control It from the Display — Point-to-Point 4K60 4:4:4 plus Keyboard/Mouse, No Switch and No Network to Engineer
EXT-HD4KFIBKVM-10KMUPC 813982022294
Upcoming · due Dec 2026
Overview
Racks a 4K source in a secure, climate-controlled equipment room and delivers its picture — plus keyboard and mouse control — to a display up to 10km away over a single fiber. The matched transmitter and receiver are compact black metal units measuring 4.72" × 3.07" × 0.96" each, drawing under 4W from a locking 5V supply, with an HDMI loop-out at the source and analog audio de-embedding at the display. It is the point-to-point choice for stadiums, campuses, hospitals and control rooms where reach, signal integrity and remote control matter more than the many-to-many switching of an AV-over-IP fabric.
The link carries true 4K60 4:4:4 at 18Gbps (HDMI 2.0b) with HDCP 2.2 and full HDR10, HDR10+, Dolby Vision and HLG pass-through, alongside LPCM 7.1 and the lossless Dolby and DTS bitstreams, so chroma is not subsampled across the run. a USB keyboard and mouse at the receiver control the computer at the transmitter for KVM control of the source from the display end, advanced EDID management resolves the connected sinks automatically, and 10G SFP+ / LC optics let the integrator match the module to the fiber plant — single-mode to 10km or OM4 multimode to 300m. Its strongest differentiator is combining 4K60 4:4:4 and USB KVM on one point-to-point fiber link, where the long-run fiber extenders that reach this far are otherwise video-only.

What ESD protection does the EXT-HD4KFIBKVM-10KM provide?
It meets IEC 61000-4-2 with +/-8kV air-gap discharge and +/-4kV contact discharge protection.
What is the highest resolution the EXT-HD4KFIBKVM-10KM passes?
It handles resolutions up to 4096x2160p60 and 3840x2160p60, and also carries 1920x1200p60RB, 1080p, and 720p formats.
How does the EXT-HD4KFIBKVM-10KM carry keyboard and mouse control into a system?
It passes USB 1.1 keyboard and mouse from the receiver's K&M ports to the computer on the transmitter's USB HOST port: connect the computer to the transmitter's USB HOST port and the keyboard and mouse to the receiver's K&M USB-A ports, so an operator at the display end can drive the source computer
How does the EXT-HD4KFIBKVM-10KM fit into an audio setup?
The receiver de-embeds audio to a 3.5mm analog AUDIO OUT jack, so you can connect 2.0 speakers or an audio device at the display end.
What fiber and connector does the EXT-HD4KFIBKVM-10KM link use?
The link runs on a 10G SFP+ module with an LC connector: connect the transmitter's LC FIBER OUT to the receiver's LC FIBER IN with a single fiber-optic cable.
What plugs into the transmitter and receiver of the EXT-HD4KFIBKVM-10KM?
At the transmitter, connect the source to HDMI IN, a local display to the HDMI loop OUT, and a computer to the USB HOST (USB-B) port. At the receiver, connect the display to HDMI OUT, speakers to the 3.5mm AUDIO OUT, and a keyboard and mouse to the K&M USB-A ports.
My keyboard and mouse do not work over the EXT-HD4KFIBKVM-10KM. What should I check?
Confirm the computer is connected to the transmitter's USB HOST (USB-B) port and the keyboard and mouse are on the receiver's K&M USB-A ports. Then confirm the fiber link is established, shown by a green LINK LED on both units, since the USB traffic rides that link.
The EXT-HD4KFIBKVM-10KM shows no image at the display. What should I check?
Confirm the transmitter's POWER LED is red and the IN LED is green, which shows a source signal is detected on the HDMI IN. Then confirm the LINK LED is green on both units for a normal fiber signal, and check the OUT LED, which lights when a display is connected to the HDMI output.
What does the KVM do — will my keyboard and mouse work at the display end?
The receiver carries a USB keyboard and mouse connection back to the source, so an operator at the display can control the PC, server or NVR sitting at the transmitter. It is a keyboard/mouse (HID) channel over USB 1.1, not a general-purpose USB 2.0 hub, so confirm peripheral needs if a customer exp
What's in the box and how does it install?
The kit is a matched transmitter and receiver in black metal enclosures, each 4.72 by 3.07 by 0.96 inches, two multinational locking 5V/2A power supplies, a USB cable, and four mounting ears with screws for surface or shelf mounting. Documentation is digital, accessed from the QR code on the box.
