8K Detachable Full Fiber Optic Armored HDMI 2.1 Cable 50FT, Ultra High Speed 48Gbps, Support 8K@60Hz 4K@120Hz, Dynamic HDR, eARC, Compatible with TV/PS5/Xbox/Blu-ray/Monitor/Projector

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.

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!

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!

Absolutely thrilled these are now available, they work perfectly over distance and resolve many known cabled HDMI issues

Really great quality product. Ran it to connect tv to av equipment that are opposite end of the room. The cable if thin to easier to pull through. The detachable heads means it's easier to upgrade

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.

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.

I originally had some 5m high quality HDMI cables running from my cabinet through the wall to my tv but given the were running parallel to a power and coaxial cable I was getting single noise. These cables have completely solved my issues. I have extensively tested at 4k50Hz but don’t have a 120Hz source. The cables do stick out a bit but this is what it looks like on an LG b8 OLED, it can’t be seen unless looking at from the side. If you power the cable from the TV, the tv won’t turn on when you turn on the source but if you power separately from the TV I can confirm it does.
