What Is the UHD-FO10-K?
The OREI UHD-FO10-K is an 18Gbps HDMI over Optical Fiber Extender with Audio Extraction designed to extend HDMI signals over long distances using single-mode fiber cable.
It can extend an HDMI signal up to 33,000 feet / 10km over single-mode fiber cable. It supports video resolutions up to 4K@60Hz 4:4:4, HDMI 2.0b, HDCP 2.2, HDR, 3D, and high-bandwidth HDMI audio formats.
The system includes a Transmitter and Receiver. The Transmitter connects to the HDMI source and sends the signal through optical fiber. The Receiver connects to the remote HDMI display and outputs the signal. The Transmitter also supports HDMI loop output, audio embedding, and EDID management, while the Receiver supports audio extraction through a 3.5mm audio output.
The UHD-FO10-K also supports bi-directional IR control and RS-232 pass-through, allowing users to control the source device from the display side or control the display device from the source side.
The UHD-FO10-K is useful for home theater systems, conference rooms, classrooms, houses of worship, control rooms, commercial AV installations, auditoriums, digital signage, projector installations, and long-distance HDMI runs where copper HDMI or CAT cable is not practical.

The UHD-FO10-K supports very long-distance HDMI transmission.
| Cable Type | Maximum Distance |
| Single-mode fiber cable | Up to 33,000ft / 10km |
| Multi-mode fiber cable | May work, but distance is not guaranteed |
The manual states that multi-mode fiber may be possible with the included SFP modules, but the distance cannot be guaranteed.
For the most reliable installation, use single-mode fiber cable.
IMPORTANT — Supports 4K@60Hz 4:4:4
The UHD-FO10-K supports high-quality HDMI video.

| 11 | Copy Receiver HDMI OUT |
| 10 | Copy Transmitter HDMI LOOP OUT |
| 01 | 4K60_2CH |
| 00 | 1080P_2CH |
Use EDID management if:
- There is no video
- The wrong resolution is displayed
- The source outputs 4K when the display only supports 1080p
- Audio format compatibility issues occur
- The local display and remote display support different resolutions
- The source needs to be forced to output 4K60 2CH or 1080p 2CH
After changing EDID, power cycle the HDMI source so it can read the new EDID setting.
IMPORTANT — Bi-Directional IR Control Is Supported
The UHD-FO10-K supports IR control in both directions.

Fiber Cable Requirement — Critical
Use single-mode fiber cable for the rated distance.
| Fiber Requirement | Specification |
| Recommended fiber | Single-mode fiber cable |
| Connector type | LC |
| Maximum distance | Up to 33,000ft / 10km |
| Multi-mode fiber | May work, but distance is not guaranteed |
Poor or incompatible fiber cable may cause:
- No video
- FIBER LED not lighting
- Signal dropouts
- Flickering
- Black screen
- Intermittent connection
- No HDMI output on Receiver
- Audio dropouts
- IR or RS-232 pass-through issues
For troubleshooting, check the fiber cable, LC connectors, SFP modules, and cable type.
HDMI Cable Requirement — Critical
Use high-quality HDMI cables capable of 18Gbps bandwidth.
| HDMI Requirement | Specification |
| HDMI version | HDMI 2.0b |
| Video bandwidth | 18Gbps |
| Maximum resolution | 4K@60Hz 4:4:4 |

- If using Receiver AUDIO OUT, check the 3.5mm audio cable and connected audio device.
- Set the HDMI source audio to PCM stereo for analog output compatibility.
- Check EDID setting.
IR Requirement — Critical
Use the correct IR cable placement.
| Cable | Placement |
| IR Receiver cable | Place where the remote control will be used |
| IR Blaster cable | Place near the IR window of the device being controlled |
If IR does not work:
- Confirm IR IN and IR OUT cables are not reversed.
- Confirm the IR Blaster is aimed at the source or display IR window.
- Confirm the remote battery is working.
- Confirm the IR frequency is within 20kHz–60kHz.
- Test short distance first.
RS-232 Requirement — Critical
RS-232 pass-through must use the correct wiring and baud rate.
| RS-232 Requirement | Specification |
| Connector | 3-pin 3.81mm Phoenix |
| Baud rate | 4800–115200bps |
| Direction | Pass-through between Transmitter and Receiver |
If RS-232 does not work:
- Check TX / RX / Ground wiring.
- Confirm both connected devices use the same baud rate.
- Confirm the Phoenix connector is seated correctly.
- Test with a known working RS-232 command.
- Check fiber link status.
Power Requirement — Critical
Both Transmitter and Receiver require DC 5V/1A power.
| Power Detail | Specification |
| Power adapter input | AC 100–240V, 50/60Hz |
| Power adapter output | DC 5V/1A |
| Transmitter power consumption | 3.85W max |
| Receiver power consumption | 2.7W max |
If either unit does not power on:
- Check the DC 5V power adapter.
- Confirm the outlet is working.
- Check the POWER LED.
- Try the other included power adapter.
- Power cycle both units.
Surge protection is recommended.
Understanding the Application Example
The application diagram shows the Transmitter connected to a DVD or Blu-ray player through HDMI IN. The Transmitter HDMI OUT loop port connects to a local UHDTV. LINE IN can connect to an MP3 player, and RS-232 can connect to a laptop or HDMI matrix device with RS-232.
The optical fiber cable connects the Transmitter to the Receiver. On the Receiver side, HDMI OUT connects to a projector, AUDIO OUT connects to a speaker, and RS-232 connects to a compatible control device. IR Receiver and IR Blaster cables are shown on both sides for bi-directional IR control.
This shows the main use case: an HDMI source is extended over optical fiber to a remote display, while local loop output, external audio embedding, receiver-side audio extraction, IR control, and RS-232 pass-through are also available.
