8K Detachable Pure Fiber Optic Armored HDMI 2.1 Cable 10FT, Ultra High Speed 48Gbps, Support 8K@60Hz 4K@120Hz, Dynamic HDR, eARC, Compatible with PS5/Xbox/HDTV/Blu-ray/Monitor/Projector

The media could not be loaded. I really like the idea that I can push greater bandwidth over longer distances with this new powered fiber Hdmi. The sleek design makes it easy for inwall installation and the output does indeed meet the advertised specs. So far the cable meets all my expectations and will more than likely upgrade my whole house with these here soon.

I purchased the 85 ft length cable and it worked flawlessly. eARC is typically buggy, glitchy, or doesn't work at all and it worked perfectly at this cable length. I only had to install the USB on the source (TV) end and a USB port on my TV was enough to power it.These cables are really convenient to install, since the HDMI plug is detachable. The fiber cable itself is extremely thin, so it's easy to route and pull through.Highly recommend this compared to other copper cables, and the detachable ends make it even easier to install and also easier to repair if something happened to the plug itself.

Can confirm this is the solution to long(er) distance 4k transmission. I have a UST projector across the room from my AVR and PS5 setup with a little less than 50' of smurf tube connecting them. Previously purchased a cheaper 50' optical HDMI that had a power adapter for one end. I got intermittent audio and video drop to the projector. The first time I plugged this in the check it fixed the problem. It was also much easier to run through the tube with the removable HDMI heads. This thing is worth every penny if you're having connectivity problems with a long run of HDMI. I will add that there seems to be a little bit of an issue with CEC when turning the devices on, but I'm switching to a SofaBaton anyway so not a big deal. Don't know about you but I'll use two remotes forever if it means the audio and video works like it should.

The need for another 30+ft HDMI cable came up and after my very positive experience with my previous RUIPRO cables, I sprang for the new Gen 4 HDMI 2.1 fiber optic cable. (33ft, armored)The thickness reduction, even with the 'armored' version, is immediately obvious and a major improvement over Gen 3. I can now hide the cable behind an ethernet run. Unpacking was all very nice and premium and the cat came over to give his own review. Cat approved.Setup itself is different, see pictures, but you can tell they put care into protecting the components until final installation. Definitely read that carefully. I don't have a use-case to install this behind dry-wall, but I imagine this new procedure better accommodates that setup, avoiding having the larger HDMI connector need to be run through walls.Functionally, cable works perfect. 4k 120hz was recognized immediately by Windows with HDR10. My EVGA 3080 Ti + Sony X900H system has had compatibility issues with other 2.1 cables, but this brand has been without fault.I haven't had the need to contact support with my last Gen 3 cable as it has been working without any issues. But from previous experiences, their customer support is why you pay more for this cable. Oher reviews have echoed that. These HDMI 2.1 cables require good standards to work right and maintain compatibility. Happy that these RUIPRO cables just work and going to use the old cable for another PC.

Previous cable Audioquest Forest 10'. Output from Legion 9i Pro @ Native 4K, 10bit, full range, color bypassed to reference, RTX on, 120hz. HDMI transmit powered by 5v output from Topping P50 PSU and receive powered @5.25V (SMPS w/buck regulator). I placed Ifi HDMI iSilencers at each end for surge protection. Colors are saturated, gradients smoother under motion, with increased contrast. I do not output audio. Primarily for gaming with Reshade using Lilium's HDR inverse tonemapping and autohdr64. Phenomenal performance. I'm ditching copper for video. Only using copper HDMI for I2s (Matrix SPDIF3 into SMSL VMV D12Se2).

the cable is very nice and the packaging was quality to protect it. the connector is a bit bulky though. All in all it works fantastic and would buy another when needed.

i purchased a competitor cable from Fiber Command for more than double the price. Unfortunately that cable didn't support CEC nor supported eARC only ARC. I stumbled upon this one after an ad recommendation and this cable is indistinguishable from a regular HDMI in terms of functionality. I am using it to run about 30 Feet to my movie room projector back to a Denon receiver in another closet. Support is also great and responds quickly to inquiries regarding functionality. Just one thing to note is you need both ends powered in order to use CEC functionality. Also make sure if you don't use the included MPO cable and need to purchase a Standard MPO cable, that its Type-A ( Straight Through ). I tried to re-use the in wall cable from another vendor and found out the hard way. Otherwise good quality and i highly recommended for the price. Only small wish is that the power port is USB-C instead of mini but just a nitpick

If you’re running a long-distance setup or need the best possible signal for gaming and home theater, this cable is absolutely worth the investment. It delivers rock-solid performance, future-proof specs, and an easy installation experience.”
