RUIPRO 8K Fiber Optic HDMI Cable, CL2, 50 ft (Gen3/C)
A solid long run HDMI 2.1 cable for projectors and in wall runs; mind the direction.
The short version
- Projector owners running HDMI across a ceiling
- Anyone running HDMI through a wall or over 25 feet
- Gamers who want 4K 120Hz from a console or PC far from the display
- Your run is short enough for a regular copper Ultra High Speed HDMI cable
- You need a cable that works in either direction
- You require official HDMI Ultra High Speed certification
What owners like
- Holds 4K and higher signals over distances where copper cables fail
- Thin and flexible for its length
- Simple setup with no external power
Common complaints
- Only works when the SOURCE and DISPLAY ends are connected the right way round
- Needs testing before it goes into a wall, since a fault is hard to fix after

What it does
A 50 foot fiber optic HDMI 2.1 cable from RUIPRO, rated CL2 for in wall runs, carrying up to 48Gbps for 8K 60Hz and 4K 120Hz.
- Fiber optic core keeps signal over long runs where copper HDMI can drop out
- CL2 jacket rated for running inside walls
- Thin 0.23 inch cable that is easier to route than thick long copper runs
- Supports 4K 120Hz, VRR and ALLM for current consoles and graphics cards
- Plug and play with no separate power supply
A sensible pick for long runs where copper HDMI struggles, such as a ceiling mounted projector or a TV across the room from the receiver. The trade-offs are that it only works in one direction, it is not the HDMI certified version RUIPRO also sells, and it costs more than copper cables that are fine for short runs.
