8K Full Fibre Optic HDMI 2.1 Cable, Detachable, Armoured, 15 m | Full fibre optic design reduces EMI versus copper cables; detachable modules help avoid replacing the entire in-wall cable

After wasting time and money on multiple “HDMI 2.1” and “Ultra High Speed” copper cables (including well-reviewed ones), all of which failed with HDR enabled, I finally accepted the reality: at 5 meters, passive cables are mostly marketing. The RUIPRO Gen4A fiber optic HDMI is the only cable that worked reliably. It handles 4K HDR at 165Hz without flickering, signal drops, black screens, or audio issues. Rock solid, even under sustained use. This confirms what most listings don’t admit: many HDMI claims are advertising, not engineering. If you actually need high bandwidth HDR at longer distances, fiber is not optional. it’s the solution. Expensive compared to copper, but cheaper than buying and returning multiple “certified” cables that don’t deliver. Also surprisingly thin and flexible for such a quality. Highly recommended if you care about stability instead of labels.

Had a really tricky cable run to do and a regular thickness cable wouldn’t cut it. Gave this 12m version a try and works flawlessly with the added flexibility of it being able to run up a dot & dabbed plasterboard wall. I am running a gaming PC at 4k 120hz resolution to a TV screen in another room and works great. I had to power the screen end adaptor with the included USB cable. Not cheap but well recommended if you have a tricky cable run and need something much thinner and want to run at a high resolution for PC gaming, PS5 or Xbox.

Very impressed with this cable. It worked perfectly for my setup - 8K @ 60hz, HDR and VRR / Gsync from PC to AVR Receiver then on to TV. Installation was easy and the removable heads a good idea. I bought this cable as I was getting a lot of EMI from PC GPU over a copper HDMI cable. The interference was causing a buzzing noise in my speakers, this was even when watching something else from a different device! The fiber optic cable electrically isolated the PC and solved the buzzing!!! Very impressed!

Only tested at 4K 60Hz for now... but works perfectly. Powers on fine with the TV using the USB cable. This was pretty much the only 48Gbps cable I could find with detachable ends as well as a black cable. Much cheaper than other places selling separate MPO cables and HDMI converters. The description says the cable is armoured but indoor rated only... I've used it outdoors anyway to go from the PC upstairs, out down the exterior wall and back into the living room to the TV. It's survived fine out there so far. The cable is only 2-3mm thick and very bendy (although you do need to avoid sharp bends or kinks). If it deteriorates then the fibre cable itself can be replaced with another 10m MPO, whilst keeping the HDMI converters in place.

Fantastic cable - only minor downside is display side requires you to connect micro USB power to the connector HDMI ( provided in the box ) and it is looks a little flimsy/fragile , otherwise does exactly what it says.

Cannot recommend highly enough. Beautifully packaged premium product that solved what I had thought was an unsolvable problem. My projector is 20m from my AV receiver and was getting ‘no signal’ from another (cheaper) optical HDMI cable. I was convinced the projector was at fault and was on the verge of shelling out for a new one. I bought this cable as a last ditch attempt and it worked straight away, I needed to connect the usb power at both ends. Now have a solid 4k link without any dropouts - if you need a long run hdmi don’t look any further than this but of kit. Would give 6 stars if I could!

An excellent product that resolved some HDMI handshaking issues that prevented 4k pictures on our tv positioned some distance away from our "media cupboard". The modular nature made the fibre installation through walls so much easier, just make sure you keep the included and fitted protective caps on the various ends and connections. The packaging is excellent and feels premium, with clear and concise instructions included. Recommended to help fix/prevent connections for your tv over long distances.

Just six months in using this 'holy grail' of HDMI cables and it's not fit for purpose. I ran this in my home theatre in trunking from Denon AVC-A1H amp to a Sony OLED A90J. Started off fine as it said it was good for up to 15M, however, I have had all sorts of drop outs in Audio and Picture. Firstly I thought it was the Blu Ray Player that was going to the amp, but then found that even on 4K Amazon and Disney+ apps there are sparklies appearing on the screen. It's such a disappointment and I am not prepared to rip out the old one to put a new one in. Complete waste of time and I would suggest anyone looking at this take extreme caution from someone who has 30 years AV experience and has used it. Wish I could send back!

Qualité impressionnante. J’ai la version 10m connectée entre ma PS5 et ma tv oled 4k. Tout passe : VRR, ALLM, HDCP, HDR….

Wow this is premium! It resolved ALL my EMI interference static sound problem with my home theater. The quality of the product is the best I've ever seen. Would buy some more if I ever get the money for sure!

I bought this for a difficult 100 ft HDMI run from my equipment area to an 83" Sony OLED, going through a Denon AVR-X3800H. I had been fighting random HDMI blackouts/handshake issues for a long time. My previous setup worked just well enough to be frustrating — sometimes it would run for 10–20 minutes, sometimes only a few minutes, and then I’d get a short black screen. I tried many different settings on both the Sony TV and the Denon receiver: CEC, ARC/eARC, enhanced HDMI modes, different HDMI inputs, and other combinations. I could improve things a little, but I could never get it fully stable. I also tried an HDMI-over-Cat7 extender before this. That worked for basic video, but the handshake was slow and the picture never felt quite like a clean native HDMI connection. This RUIPRO cable fixed it immediately. I tested it on the floor first before putting it in the wall. It ran clean all day and evening with the TV and Denon back on their normal/default settings. No flickers, no blackouts, no long wait for the picture to stabilize. The detachable ends were a big deal for me. I still had to work to get it into the wall, but the smaller cable end made the install possible without completely tearing things apart. I powered the display/TV end with USB as instructed. Bottom line: if you are trying to do a long HDMI run to a good TV/projector and you’re getting random blackouts or handshake problems, this cable is worth trying. For my Sony OLED + Denon AVR setup, it solved a problem that multiple other approaches did not.

Calidad excelente, fácil de utilizar y pasar por paredes. Calidad de imagen espectacular

The product has been fantastic so far! I’m using it with my Nvidia Shield Pro, Denon 11.2 receiver, and a 4K laser projector setup. The main reason I purchased this product was to resolve issues with my old HDMI cable, which was routed through the ceiling and couldn’t support HDR10. This new product caught my attention because it supports all the latest standards and delivers uncompressed data at speeds of up to 48Gbps. With those specs, I knew I had to give it a try. So far, it’s been a great solution to my issue. I’ll provide updates regarding quality or any potential issues as I continue using it. -UPDATE- I have been using the product for the last 2 months without issues or concerns. I am now able to watch HDR10+ source without any degradation in picture quality or loss of picture.
