8K Fiber Optic HDMI Cable 6ft, 48Gbps Ultra High-Speed HDMI 2.1 Cable 8K@60Hz 4K@120Hz Dynamic HDR/eARC/HDCP 2.3, Directional HDMI Cord Compatible with Game Console PS5 Xbox Series X/Blu-ray/TV etc

This HDMI fiber optic cable did what a Panamax MRS 5100, premium power, careful grounding, and sheer force of will could not: it told electrical noise to sit down, shut up, and leave my living room. Context. I own a Samsung Q900T 8K TV that costs roughly one kidney, part of a lung, and most of my dignity. I also run an aggressively obnoxious audiophile setup—the kind where guests stop mid-sentence and say “why does it sound like the band is here.” Everything was perfect except for one villain: ground interference bleeding from the TV into the audio chain like an electrical poltergeist. Buzzing. Feedback. Subtle but infuriating. The kind of noise that makes you question your life choices and stare at your rack at 2 a.m. swapping cables like a mad scientist. Even with the TV plugged into a very expensive Panamax power conditioner that promises to tame lightning strikes and minor deities, the noise persisted. Enter this cable. This thing does not transmit electricity. It transmits light. Literal photons. Zero shared ground. Zero electrical nonsense. Just tiny disciplined beams of light carrying HDMI data like monks delivering sacred scrolls. Result: about a 99% reduction in interference. Not “a little better.” Not “audiophile placebo better.” Actual, measurable, immediate silence. The noise floor dropped so hard it needed medical attention. My system went from “amazing but haunted” to “why is everything so clean and calm.” Picture quality? Perfect. Audio? Untouched, except now it isn’t being strangled by Samsung’s electrical chaos. My setup finally sounds like it costs what it cost, which is an amount I refuse to calculate for mental health reasons. If you’re running high-end audio with a modern TV and hearing mysterious garbage you can’t eliminate, this cable isn’t an accessory. It’s an exorcism tool. It replaces copper with physics and solves a problem that money alone could not. Five stars. Would buy again. Would trust with my remaining organs.

After getting a 4K LG OLED TV, running @ 120hz with Gsync, and Media Center PC running an RTX 3070, I discovered that the only way to drive the TV at it's full capabilities (120hz @ 4K) without resorting to some sort of display compression that sacrifices picture clarity, was with a 48Gbps 8K HDMI 2.1 Cable. The next step down is an 18Gbps HDMI 2.0b, which can only drive 4K @ a max 60hz without compression. Every Single 48Gbps HDMI cable I could find was THICK, which it turns out is necessary to carry the higher frequency signal on copper wires. I have a lot of cables routed around and bundled though rather small conduits, and whenever possible use as thin a cable as possible Enter Fiber Optic cables. They can support 48Gbps while keeping thin, but there aren't many out there - most are very long (100' +) and very expensive. This one looked too good to be true - a real 48Gbps cable that's thin, short and cheap. I ordered one, swapped the firehose sized 2.1 cable out for it, and song of a gun .. It Just Worked. I'm running 120 Hz @ 4K no problem with an 8-bit uncompressed signal (I haven't tried getting 10-bit/HDR working yet). And its nice and thin - perfect for the small conduit I have. Happy! Happy! Happy!

I'm a gamer and so is my brother and this cable made such a huge difference in response time, its to the point where I caught me off guard when playing Apex, I'm getting 2 to 3 more kills per game. It feels as if I'm getting zero letancy. My TV is hdmi 2.1, but it would still make a big difference on any monitor or TV. Picture quality and motion improve so much more, you just gatta see for your self. Colors pop much better and HDR never felt more natural and realistic. Dolby vision is a delight, sound quality improved, feels more alive. This ain't no placibo effect alright. I know exactly what I'm talking about and fiber is always going to be much better than copper. Don't doubt your self about buying this cable, for the price and length, you're getting a great quality product and deal that does supports all Hdmi 2.1 features. Because of this same reason and more that I didn't feel like typing, I'm switching all of my cables to fiber and to be more specific to this brand of cable.!!!

Cables showed up in nice packaging and it’s nice to see the company update their description. I did not originally know they were directional and have to be installed with 1 being the source and 2 being the display. After 15 minutes of no image and troubleshooting, I saw a separate email from the company via Amazon explaining how the cables only send signals one way and after turning the cables around… Amazing picture quality! 4K has never looked better. Ran one set through a 4K Apple TV and another through an Xbox series x. into the 4K 120hz TV and a vast improvement over 1.0 HDMI cables. It’s been a week with these across three systems and worth the money. Great speed across the cables and great images.

Updated 2: Trashed (in recycling bin). My other 3-ft & 6-ft follow the same fate. After a month or so, Signal lost (blank screen). This brand, “fiber” and thin wires, you get what you pay for. I will never go for this brand or “fiber” ever again. Updated1: So I bought, 3ft (two) and 6ft a month or two ago. The 6-ft have worked flawlessly (not any more read update 2). Sadly the 3-ft, not so much. It keeps blanking out (black screen). I have lost hope now for “fiber” cables. Initial Review (not true anymore): First, I was using a so call “8K 10K HDMI Cable 48Gbps” by Highwings between a 4K TV and M3 MacBook Pro, and it was fine but with slow startup (blank screen for a few seconds when turn on). This was until I bought a 4K HDR 144hz monitor. It wouldn’t work properly, slow starting up again and early cutting out intermittently to the point it would prompt me to re-login sometimes more than once. Now, with this so call “fiber” cable, all those issues disappear, no more problems. Wow, I was so surprised! I was skeptical about it but no more. I’m now going to order another for my PC. Let’s hope it works for a long time. If anything, I will update it here.

I’d give five stars but there is one very minor issue I have. I use it on my Xbox series x and sometimes when I turn it on there is no picture output until I unplug and plug it back into the Xbox. I’ve never had that issue with normal hdmi cables. Not sure the cause or if I maybe got a dud. Other than that the picture and sound quality are great.

So I replaced a 25ft copper hdmi cable with this 24ft fiber optic cable from my pc to my AVR. And the difference is quite noticeable. I have better audio and video. So I am quite pleased with this upgrade. 5 stars ⭐️🔥

Nothing better than fiber. My TV plays Dolby ATMOS-MAT. It automatically switched from Dolby ATMOS-DD+ even on WiFi! These are 100% fiber HDMI cables. Don’t let the TROLLS fool you!

Excellent product. Absolutely what I needed, and fully met my expectations. Only thing is that I'm unable to test if 120Hz is carried as described. However, performance is great with no dropouts or artifacts at least at 60Hz. Very light and easy to manage cable. Nice seller who contacted me several time by WhatsApp, but something is wrong with the Amazon tracking as it is still showing in my orders as not shipped. It arrived in 16 days..

The Cables are much thinner and more flexible, while this may not sound like a big deal it can make a huge difference over longer lengths as the longer lengths of the copper HDMI cables get rather bulky and stiff making them a nightmare if you want to run them through any kind of conduit. these Fibbr Cables are a dream to work with. The Tv also responds noticeably quicker using these cables even though I'm using them on a HDMI 2.0 Port (18 gigabit per second) not a HDMI 2.1 (48 gigabit per second port). The Cables also come very well packed, in a nice reusable Ziploc style bag with Velcro ties for easy cable management which was an unexpected bonus. I am never going back to the older cooper style cables. I sound like a commercial..yikes... anyway awesome cables and they aren't crazy expensive.

Works great

Got the 24 foot version and used it to connect my XBox Series X to my 77" LG C1 OLED. I was able to max out all the settings, 4K HDR 120Hz and Dolby Vision worked flawlessly. I also used eARC to send audio to my Denon X1600H and it worked flawlessly. Would definitely recommend this cable, especially since it's the cheaper fiber optic HDMI cable compared to other brands on Amazon.

This cable i use apple tv i get good picher good audio also realy very good
