AV Access 4KEX300-F High-End 4K Fiber HDMI Extender, up to 300M/1000ft over Fiber Optic Cable, HDMI 2.0 Transmitter & Receiver Kit, 2-Way IR & RS232
Carry a 4K signal across a much larger space.
Place the source equipment where it belongs and keep the viewing area uncluttered. 4KEX300-F carries HDMI video and embedded audio between a matched transmitter and receiver over Duplex OM3 multimode fibre, 850nm, LC–LC, making longer installed connections easier to plan.
4KEX300-F
Know what connects where.
Connection overview. Check the requirements below for the exact ports, cable type and supported operating mode.
Bring the picture to the right place
Use the transmitter beside the source and the receiver beside the remote display. The specified video limit is 4K60, 4:4:4; distance depends on cable type and the selected signal. Up to 300m is the relevant planning limit for this model.
Keep the remote end useful
The optical link carries HDMI 2.0 video and embedded audio alongside two-way IR and RS232 control. Its included multimode optical modules must be matched to the specified fibre type and connectors.
Plan the cable and power together
Use Duplex OM3 multimode fibre, 850nm, LC–LC. Both units require their supplied power adapters; fibre does not carry electrical power between them. Test the complete link, including short video cables at each end, before pulling cable through walls or securing equipment.
Make sure it fits your setup.
The correct cable
Duplex OM3 multimode fibre, 850nm, LC–LC. Use a properly terminated, continuous run within the documented distance.
Fibre type matters
Use the documented duplex multimode fibre and compatible optical modules. This model is a matched optical extender, not a generic Ethernet-network transmitter.
Power and peripherals
Both units require their supplied power adapters; fibre does not carry electrical power between them. This model is for video/audio extension; it is not a general USB extender.
From unboxing to connected.
Plan the link
Match the cable type, total length and required resolution to this model’s limits.
Connect both ends
Put the transmitter at the source and the receiver at the display or USB devices.
Power the kit
Use the power connection specified for this model; then check the link indicators.
Test before installing
Confirm video, sound and any USB/control functions before securing the cable run.

A little clarity before you buy.
Can I connect it through a network switch?
No. This model needs the specified direct link between its transmitter and receiver. Choose a documented AV-over-IP model for switched-network distribution.
Is the maximum distance the same at every resolution?
Up to 300m. Follow the model documentation for cable category and signal-specific limits.
What should I check if there is no picture?
Check input/output direction, power indicators and cable termination. Try a lower source resolution and a short known-good link before testing the installed run.
