RUIPRO 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

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.

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'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.

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..

Best!!!!!! HDMI 2.1 cables I love them I bought two different sized one 35 ft for my PC and 12 ft for my TV to my receiver eventually I'll buy another two more for my PlayStation 5 and my Nvidia shield TV to my receiver so far I have no problems runs great fast I wish they make one for DisplayPort for PC and wish they made a 90° down shape adapter and DisplayPort for my GPU to connect to my PC I'll definitely buy from them again

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.

It’s an expensive product, but it’s worth it. It works with my Gigabyte Eagle RTX 3080 Ti and my Xiaomi Smart LED S Mini LED 75" 2025 TV, 4K 144 Hz, with FreeSync Premium and HDR / FILMMAKER / IMAX. The only thing I didn’t like is that it doesn’t come braided and feels somewhat fragile. I had to install special cable channels to make it safe. My setup uses the 65 ft version. There is no signal loss. You need to make sure that both your TV/monitor and your GPU support HDMI 2.1. In my case, since my GPU has two HDMI outputs in use (the fiber one to the 4K TV and a regular one to a 1080p monitor), when HDR is enabled it flickers constantly, which is annoying. However, when I disconnect the regular HDMI from the monitor, I can enjoy my 4K TV 100% without any issues.
