One USB-C Cable at the Table for Video, USB Devices and 60W Charging
How one 2-gang wall-plate carries laptop video, USB camera and mic, and 60W charging to a distant display over a single CAT6/6A run.
The problem
On a campus, in a large venue or across a control-room complex, the display is often nowhere near the source. A lecture hall feeds a hall in the next building; a control room feeds a concourse; a sanctuary feeds an overflow space through a wall or two. Copper extenders run out of reach on these paths, and the signal has to cross areas full of lighting, power and broadcast equipment on the way.
Fixing that with a switched network adds encoders, decoders and a switch that all have to be configured and maintained, and it puts more devices in the signal path than a single one-source, one-display link needs.
What these jobs need is a straight run from one source to one display that holds full 4K60 with its color, HDR and audio intact over a distance copper cannot cover, without dragging in KVM, control or a network.
What changes with this product
The EXT-HD4KFIB-10KM is a two-box transmitter-and-receiver kit that sends an HDMI signal up to 10km (6.2mi) over a single-mode LC fiber cable, at resolutions up to 4096x2160 at 50/60Hz with 4:4:4 color, far beyond the reach of copper extenders. Each unit is a compact metal box with a 10G SFP+ fiber port and a USB-C service port, and the kit includes two 5V/1A power supplies.
It is HDMI 2.0b with 18Gbps of video bandwidth and HDCP 2.2. The transmitter passes HDR10, HDR10+, Dolby Vision and HLG unchanged, and carries audio as LPCM 7.1, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio and DTS:X, with the receiver outputting the same signal to one display. Color depth can be 8-bit, 10-bit or 12-bit. The design is a dedicated point-to-point link — two units and a fiber run, with no network switch in the signal path. Over multi-mode OM4 LC fiber, through SFP modules, the same kit reaches up to 300m (984ft). Fiber cable is not included.
Where it fits
Campus and Multi-Building AV
Link a lecture hall, auditorium or control room in one building to displays in another over a single-mode fiber run of up to 10km (6.2mi) at 4096x2160 50/60Hz with 4:4:4 color. HDR and lossless audio ride the same link, so the far building sees the same picture and sound as the source, past the reach of a copper extender.
Stadiums and Arenas
Run a source from a control room or plant room out to concourse, suite or field displays across the venue. It carries the 18Gbps 4K60 signal end to end over a single LC fiber run between transmitter and receiver.
Houses of Worship
Send a sanctuary feed to an overflow hall, chapel or broadcast room in a separate building at full 4K60 with HDR and multichannel audio. One transmitter at the source, one receiver at the display and a single fiber run is the whole signal path, with no matrix or control system needed to make it work.
Broadcast and Control Rooms
Move a program or monitoring feed between a control room and a remote studio, edit suite or transmission point at 4:4:4 chroma. HDR10, HDR10+, Dolby Vision and HLG pass through unchanged, and the audio formats above are carried intact, so the remote monitor shows exactly what the source sends.
Medical and Surgical Suites
Carry imaging and surgical-camera video from a room to remote review or teaching displays. A single LC run from the transmitter to the receiver keeps a long cable path through the building simple, at up to 4096x2160 50/60Hz 4:4:4 over single-mode fiber to 10km (6.2mi).
Transit Hubs and Digital Signage
Feed displays across an airport, rail station or large signage network from a central player. A single-mode run reaches up to 10km (6.2mi) at 4K60 4:4:4, covering distances copper cannot.
Typical setup
Connect the HDMI 2.0b source — a source PC in the reference diagram — to the transmitter IN port. Run an LC fiber cable from the transmitter SFP+OUT to the receiver SFP+IN: single-mode carries the link up to 10km (6.2mi) at 4K60 4:4:4. Connect the receiver OUT to the display, which shows a 4K60 4:4:4 HDR image. Each HDMI connector is an HDMI Type A 19-pin female, and the SFP+ ports use LC female connectors. Each unit takes its own DC 5V power at the DC 5V input.
What to check before you specify
- Distance and fiber type. Single-mode LC fiber for runs up to 10km (6.2mi) at 4096x2160 50/60Hz 4:4:4. The fiber module is a 10G SFP+ module.
- Cable supply. Fiber cable is not included, so specify the LC single-mode or OM4 multi-mode run separately.
- Power. Each unit is fed by its own DC 5V/1A supply with an AC input of 100-240V at 50/60Hz; two 5V/1A supplies ship in the kit. The transmitter draws 3.05W maximum and the receiver 2.25W maximum.
- Surge protection. Recommended — the units hold sensitive components that spikes, surges and lightning can damage.
- Environment. Operating temperature is 32°F ~ 104°F / 0°C ~ 40°C, humidity 20%~80% RH non-condensing.
Questions integrators ask
Does it need a switch, matrix or control system?
No. It is a transparent point-to-point extender: one HDMI source connects to the transmitter, the transmitter reaches the receiver over a single LC fiber run, and the receiver drives one display. HDCP 2.2 protected content passes straight through, with no network switch in the signal path.
What fiber does the link require?
Use single-mode LC fiber for runs up to 10km (6.2mi) at 4K60 4:4:4. The LC fiber goes from the transmitter SFP+OUT to the receiver SFP+IN.
Will it carry HDR and lossless audio?
Yes. It passes HDR10, HDR10+, Dolby Vision and HLG unchanged, and carries audio as LPCM 7.1, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio and DTS:X. Color depth can be 8-bit, 10-bit or 12-bit, and color space RGB, YCbCr 4:4:4 / 4:2:2 or YUV 4:2:0.
The display is black — what do I check first?
Confirm the green POWER LED is lit on both units, then the green LINK LED on both, which shows a normal optical fiber signal, and finally that the HDMI cables are seated at the source IN and the display OUT. If the LINK LED is unlit, the fault points to the fiber run: verify the LC fiber goes SFP+OUT to SFP+IN and that the distance is within 10km on single-mode or 300m on OM4 multi-mode.
