8K Fiber Optic HDMI 2.1 Cable 40ft, Long Active HDMI Cable, High Speed Fiber HDMI Cord, 48Gbps, 8K@60Hz 4K@120Hz, Dynamic HDR, eARC, HDCP 2.2&2.3, 3D, for HDTV Monitor Game Laptop Home Theatre

Buying a 3.3 foot fiber optic HDMI cable may seem like overkill, since fiber optic is only “necessary” for much longer cable runs. But the advantage of even a short run of fiber optic HDMI cable is that, unlike copper, it’s totally immune to radio frequency interference (RFI), which can cause signal degradation, data loss, and — if the RFI is bad enough — malfunctions in your surround sound system. This particular cable is very well made and works flawlessly with my Roku Ultra, Denon AVR, and LG TV — all hooked up with ethernet connections in preference to wifi. Note that fiber optic HDMI cables are uni-directional, with one end labeled “Source” and the other end “Display.” If you have a streaming device and an AVR, the “Source” end of the cable plugs into your streaming device and the “Display” end plugs in to one of the HDMI ports on your AVR. You will need a second HDMI cable to run from your HDMI OUT port on your AVR (“Source”) to an. HDMI port on your TV (“Display”). Unlike copper HDMI cables, which are bi-directional, if you plug fiber optic cables in the wrong way they won’t work. For me, this was a great buy, with excellent build quality and easy installation. Last but not least, measure (twice) BEFORE you buy, and if in any doubt go for a longer cable (e.g. 6 feet). Stretching fiber optic cable is a very bad idea - both ends need to fit snuggly with no tension on the cable.

The product I received the second time around was the right one with the proper HDMI port connectors and the product is working great so far.

I got this for a specific use case that may mirror yours. I wanted to connect my RTX 5080 to a TV in my bedroom. The problem with your standard HDMI 2.1 cables at long lengths, they are a very heavy gauge, and extremely stiff. Fiber Optic hybrid cables fixes that issue entirely. They can easily send the full 48Gbps of bandwidth while also being extremely thin, about as thin as a thick spaghetti noodle. That means there is zero stress on your HDMI port, and since the RTX 5080 only has 1, I wanted to make sure it lasted. As far as reliabilty goes, it's all but a guarantee this listing won't be here at the end of 2026. These companies just constantly changing their LLC's in order to not have to honor any warranty replacements. So test it thoroughly for the 30 days you have it, and if it gives you any issues at all you should absolutely replace it. Mine has worked perfectly, and for the price I am very happy with it.

The cable worked well for 35 days and then started disconnecting whenever i turn on lights. Additionally, no actual support to the cable and i can’t even contact seller.

The first one didn't work but the service and response was quick and the second cable worked great. The cable is very thin and was easy to hide between the carpet and baseboards. It also didn't take up much room in the cord hider.

Excelente. TV smart a un teatro en casa.sony

Buen producto Buena conductividad Buen materia Buen precio

Works perfect running my pc from other side of room to my tv. Running at 4k 144hz perfectly.

Work perfectly without problems

I just got this cable but so far it's working great. I run a gaming PC on my TV, and we moved our living room around. The gaming PC moved much further away and I needed a much longer HDMI 2.1 cable and apparently the only way to get a run this long is using a fiber optic HDMI cable. This one had a great price and was on sale for about $38 for 30ft which was a little longer than I needed but I like having a little extra just in case. The cable itself works great. I'm using it on my gaming PC at 4k, 120hz but also with variable refresh rate (VRR). I've also tested it with HDR. No drop outs of any kind or any other issues it just works. I suppose it does feel a little cheap, but it was cheap, I've seen similar lengths from other brands go over $100. So hopefully this cable will continue to work as well as it's working now but so far it's perfect

Rien à dire ! Au top...

15m version, absolutely no issues with this pc to lg 4k tv. Shocked how thin wire is, just remember not like older Hdmi cables has input output sides.

Works as intended, So far no issues.
