Keyence HDMI 2.1 fibre cable 50 ft

This Keyence HDMI 2.1 fibre optic cable spans 50 ft and carries 48 Gbps bandwidth for 8K at 60 Hz and 4K at 240 Hz. It supports Dynamic HDR, eARC and HDCP 2.2 and 2.3 for protected content. The slim 0.14 in diameter suits installations where space is tight. It is aimed at installers and home users needing long runs without signal loss.

HDMI 2.1 bandwidth and directional limits

The cable delivers 48 Gbps over 50 ft, enabling 7680×4320 resolution at 60 Hz and 4K at 240 Hz. Fibre construction reduces attenuation compared with copper at this length. Transmission is uni-directional; plugs are marked SOURCE and DISPLAY and must be connected correctly or no signal will pass. HDCP 2.2 and 2.3 compliance covers current protected streams.

Build quality and connector implications

Gold-plated connectors and zinc alloy housings resist corrosion and wear. The anti-bend tail design is rated for over 10 000 bending cycles, helping the cable survive routing through walls or conduit. At 3.6 mm diameter the cable is lightweight, though the directional plugs require attention during installation. Not suited for users who need bi-directional or reversible connectivity.

Questions about this item

Should I choose the 50 ft length or a shorter run for my setup?

The 50 ft fiber optic design maintains the full 48 Gbps bandwidth over the entire distance without the signal loss typical of copper cables at that length.

What does the 48 Gbps rating actually deliver when connected to my display?

It enables 8K resolution at 60 Hz or 4K at up to 240 Hz with Dynamic HDR and eARC audio return, provided both source and display support those modes.

How does the HDMI 2.1 interface limit what I can run on this cable?

The HDMI 2.1 specification caps the link at 48 Gbps, so 8K 60 Hz and 4K 240 Hz are the maximum supported formats; higher refresh rates or resolutions would require a newer standard.
