Name: 4K60 HDMI-over-Fiber Extender with Full Control over One Fiber (10km)
Brand: KanexPro
SKU: EXT-HD4KFIBCTL-10KM

Question 1

What is the maximum video bandwidth and HDMI standard supported?

Accepted Answer

It supports up to 18Gbps of video bandwidth per HDMI 2.0b, with HDCP 2.2 compliance.

Question 2

Which HDR formats pass through the link?

Accepted Answer

It passes HDR10, HDR10+, Dolby Vision, and HLG.

Question 3

What control protocols pass over the fiber?

Accepted Answer

Bi-directional IR and RS-232 pass through over the same fiber, so you can control the source from the display end or the display from the source end.

Question 4

How do I wire RS-232 control into the system?

Accepted Answer

Connect a PC or control system to the 3-pin 3.5mm Phoenix RS-232 port on either the transmitter or receiver, and commands pass through between the two ends.

Question 5

What kind of fiber and module does the link require?

Accepted Answer

The link runs on LC single-mode fiber through a 10G SFP+ module, from the LC FIBER OUT on the transmitter to the LC FIBER IN on the receiver.

Question 6

How does each unit get power?

Accepted Answer

Each unit takes its own locking 5V/2A supply into its DC 5V input, and each supply accepts AC 100-240V at 50/60Hz.

Question 7

There is no picture on the display. What do I check first?

Accepted Answer

Confirm the red POWER LED is lit on both units, then the green LINK LED on both, which shows a normal optical fiber signal; then check the green IN LED on the transmitter for a detected source and the green OUT LED for a connected display.

Question 8

The LINK LED is not green. What does that mean?

Accepted Answer

The green LINK LED only stays on when the transmitter and receiver have a normal optical fiber connection, so recheck the fiber run from LC FIBER OUT to LC FIBER IN and that the SFP+ modules are seated.

Question 9

How far will it actually run at full 4K60 — not a downgraded 4:2:0 signal?

Accepted Answer

Up to 10km (about 33,000 ft) over single-mode fiber at 4K60 4:4:4, 18Gbps, HDMI 2.0b, HDCP 2.2. Over multi-mode OM4 fiber the reach is up to 300m. The 4:4:4 color is maintained across the run — it does not fall back to 4:2:0 to make distance.

Question 10

Why choose this over an HDBaseT extender?

Accepted Answer

HDBaseT tops out around 100m and runs on copper, which carries ground-loop and EMI risk between buildings. This kit is for runs beyond that ceiling and for any span where you need the electrical isolation of fiber. If your run is under about 100m in one building, an HDBaseT unit is the more economic
