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 PS5/Xbox/Blu-ray/TV/Monitor/Projector

Works great. I was having issues with my TV audio over eARC to the receiver that is in a closet in another room. I tested this and it worked perfectly. First cable I’ve found to give me zero issues over eARC. I already have a fiber command cable in the wall, which was extremely expensive. That cable did not work with eARC despite trouble shooting it every way possible. After confirming this cable worked. I ran it through the wall to the attic and down to the closet. Works perfectly. I would highly recommend it. Great build quality. Quality is as good if not better than the fiber command cable. If I had to do over again, I would just use these cables instead. They are much more affordable. Picture quality is great. I’m running 4K@120Hz with HDR and Atmos audio over it with no problem.

I tried about a dozen long HDMI cables to connect from my PC to my 4k TV. This is the best working cable I have tried. For me it does still flicker every once in a while, but seems to only happen when a certain program or action causes it. It's also great that the HDMI plugs are swappable and that the cable is so thin and flexible - making it easy to route. It is expensive but worth it. There are other "fiber optic" cables that are more inexpensive here on Amazon, but I tried those as well and they are junk. The only other very long HDMI cables I have tried that work well enough and are also inexpensive are the non-fiber cables that have a much thicker gauge - not sure if I can say exact brands here in the review but they are from the more reputable and "mainstream" brands. However those cables did still flicker intermittently for me, but not often enough to make them completely unworthy of using. All of this is only if you need more than a 10 ft cable. 10 ft and below and you will likely be fine with a cheaper cable.

I've tried a few AIO fiber HDMI cables in the past and have had mixed success when pushing 40-48Gbps speeds. This set works flawlessly at 48Gbps, and handles 4k@120hz, HDR, without issue. I ran into CEC problems with this set, but that seems to be a common problem depending on the make of TV and if there's a computer involved too. It's pretty easily solved with a CEC blocker, although that adds another connection to the signal chain and can degrade the connection a bit. The main downside is the size of the transceivers. Many TVs don't have enough space for it without potentially bending the HDMI connector. With a CEC blocker inserted between this and the TV too, I had to add an angle-adapter just to make it all fit. With both the extra adapters, the signal loses some stability at 48Gbit. Forcing it down to 40Gbit was enough to make it stable again without losing any features.

Perfect! I've tried couple of diffefent cheap optic HDMI cables, but they were flickering and the quality was bad. But this one is really good! I've bought 15ft long one and it can handle 4K 120Hz HDR signal from my laptop to TV without flickering or any other issues. The cable itself is also so thin, I couldn't believe my eyes. The connectors are also good! 5\5

Excellent picture quality and no latency between audio and video. I purchased the 40 foot fiber optic/HDMI unit to connect a Marantz cinema 70s to a LG tv and it works perfectly. Before this purchase, I tried hdmi over cat7 and the tv kept loosing signal(very annoying). I also tried hdmi to fiber optic (without the 5v power supply on each end) and there was a latency between audio and video. The product is pricey but worth every dollar. Don’t eff around like I did..

Pulled out older runs of copper hdmi cables and replaced with these. Way easier to run. They work great now I have them in. The only reason I knocked one star off is for the covering on the cable. If they could make it more slick and grab less it would be easier to run and be a better product.

Item works great, armored fiber helped to reduce the stress of running the fiber line through walls and attic. I used the supplied USB power on both ends to solve for CEC power issues. Great picture!

The dongle and fiber cable together work out to over 3 inches long, which means they won't fit behind most TVs. Despite being powered, the signal they produce is so weak that ANY cable or adapter in line will cause it to have intermittent signal at 4K60, with continuous drops to black screen. I've ensured that the cables and adapters I've tried are HDMI 2.1 and well rated and I've tried three different ones from different manufacturers and different form factors, but all of them eventually run into the same intermittent black screen problem. With the screen taken off the wall so the cable can directly connect it works fine. If you don't need 4K60 or you have plenty of room for a massive connector to stick out, then you may not run into this issue. If both of those are true then it will be a huge waste of time and money. That is not acceptable from an expensive, powered HDMI cable.

Funktioniert großartig. Hab damit meinen PC im Nebenzimmer mit meinem Fernseher verbunden. Funktioniert mit vollen 4k 120hz ohne Latenz. Wirklich toll, Preis-Leistung ist auch super. Ich hatte erst Probleme mit meinem Kabel mit Bildfehler oder Black screen's immer wieder. Der Support hat unkompliziert einen Ersatz zugeschickt. (Lag an den HDMI Endstücken, nicht am Glasfaser Kabel) Seitdem keinerlei Probleme mehr.

Amazing product

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.

Bon produit

Doet wat het belooft! Was even spannend omdat ik deze kabel samen met een UTP door een 19mm buis moest trekken. Met bescherming dop was dit overigens niet te doen omdat deze een stuk dikker is dan de MPO connector zelf, dus uit soort van laatste poging met een stukje tape om de connector heen om deze te beschermen (elektrische tape gepakt) en een schietgebedje weer geprobeerd. Uiteindelijk zonder beschadigingen kunnen trekken en werkt helemaal top! Ben benieuwd op de langere duur hoe het zich houdt :P.
