USB-C 4K60 Extender Over Fiber: What It Does

EXT-USBC4KFIB-10KM EXT-USBC4KFIB-10KM Native USB-C DisplayPort Alt Mode 4K60 Extender over Fiber — 10G SFP+, up to 10km Extend a USB-C Source Without Dongling to HDMI - Full 4:4:4, HDR Pass-Through, EDID from… Product page →

What the EXT-USBC4KFIB-10KM does

The EXT-USBC4KFIB-10KM is a point-to-point fiber-optic extender kit: a matched transmitter and receiver that carry a native USB-C DisplayPort Alt Mode video and audio signal from a source to a remote display. The source USB-C output plugs straight into the transmitter IN port, the signal travels over LC fiber on a 10G SFP+ module, and it arrives as native USB-C again at the receiver OUT port — no dongle at the source and no 100m copper ceiling. Both endpoints are compact black metal units, 3.19 × 1.93 × 0.98 in (81 × 49 × 25 mm) each, weighing 0.30 lbs (138 g).

How far can it send the signal, and over what fiber?

The link runs up to 10km over single-mode fiber at 4K60, with OM4 multi-mode fiber supporting shorter, plant-matched runs instead, using a 10G SFP+ module with LC connectors at each end. The same transmitter and receiver serve either run — you swap the optic to match the fiber plant you already own, rather than changing extenders. SFP+ modules and fiber are selected to match the run and sold separately. The green LINK LED stays lit only when the transmitter and receiver have a good optical connection, so if it is off, check the LC fiber between the transmitter SFP+ OUT and the receiver SFP+ IN and confirm the run matches the fiber type in use.

Video bandwidth is 32.4 Gbps, supporting HBR3, HBR2, HBR and RBR at 8.1, 5.4, 2.7 and 1.62 Gbps. The link holds 4K at 60Hz in full 4:4:4 color, and resolution reaches up to 4096×2160p60/50, 3840×2160p60/50/30/25, 1920×1200p60RB, 1920×1080p60/50, 1280×720p60/50 and any VESA-standard resolution. Color space covers RGB, YCbCr 4:4:4/4:2:2 and YUV 4:2:0 at 8-bit, 10-bit or 12-bit depth. HDR10, HDR10+, Dolby Vision and HLG pass through, and audio includes LPCM, Dolby Digital/Plus/EX, Dolby TrueHD, Dolby Atmos, DTS, DTS-EX, DTS-96/24, DTS High Res, DTS-HD Master Audio and DTS:X — the same across the full reach the fiber type supports. HDCP 2.3, 2.2 and 1.x are supported.

How does the source read the remote display's EDID?

EDID passes from the receiver back to the transmitter, so the source always reads the connected display's capabilities across the fiber run. If the picture is up but the resolution looks wrong, confirm the receiver is powered on with its POWER LED lit and that the display is connected to the receiver OUT port — with that path intact, the source can read the display over the link.

How is each unit powered, and what does an install need?

Each end has its own DC 5V/1A power input, fed by an included multinational supply rated AC 100–240V, 50/60Hz. The transmitter draws 2.7W maximum and the receiver 2.5W maximum. Both units contain sensitive electrical components that can be damaged by spikes, surges, shock or lightning, so a surge-protection device is highly recommended to protect and extend the life of the equipment. Each unit also carries a SERVICE port — a USB-C update port used for firmware updates. The kit is CE, FCC and UL certified, and rated for operation from 32°F to 104°F (0°C to 40°C).
