FIBBR 8K Fiber Optic HDMI Cable 3ft, 48Gbps High-Speed HDMI 2.1 Cable 8K@60Hz 4K@120Hz Dynamic HDR/eARC/HDCP 2.3, Ultra HD Directional HDMI Cord Compatible with LG Samsung Sony TV /PS5/Blu-ray

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.

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.!!!

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 had signaling issues from running at 4K120 over just a 5 meter normal HDMI cable; the TV screen would often blank out intermittently. This fiber optic one surprisingly outputs 4K at 120 frames per second with zero issues even at 10 meters and is much lighter weight (for holding up with tape for example). Normally the issue is that fiber optics cost an arm and a leg, but I was pleasantly surprised to find them at this price point. Best to buy these for either very long cable runs or to reduce the cable weight; a normal HDMI cable otherwise suffices. Edit: As a surprising bonus that I guessed would work, they're also immune to noise, so use it with poorly behaving converters. I have a poorly shielded HDMI adapter for my Wii that would cause lines to appear on the picture, and swapping out the copper HDMI cable for this one fixed my issue.

While reconfiguring my home theater connection, I decided to change the HDMI cable, which is about 15 feet long. Up until now, I used a very stiff, thick, old, and quite expensive HDMI cable to connect, but this HDMI cable was so stiff and tight that it came off by itself when I moved the device. Then I found the Fiber Optic HDMI cable below on Amazon. [8K HDMI Cable 15FT/5M, FIBBR 48Gbps High Speed HDMI 2.1 Cable 8K@60Hz, 4K@120Hz/144Hz eARC HDR HDCP 2.2 & 2.3, Slim Fiber Optic Cable Compatible with HDTV/PS5/Blu-ray]. Ordered and to my surprise it arrived the very next day. I was very surprised after receiving the item. This cable is soft and the thickness is thinner than the RCA audio cable I was using, so it was great to connect devices and organize the wires. But on the other hand, I was a little worried about whether this cable would come out well. I am not an expert on the performance of cables and there is no way to measure their performance. First, I unplugged the old HDMI cable and connected a new one. The clear video of the 77-inch LG OLED TV screen came out, and I could hear the sound through the speakers and subwoofer connected to the home theater. With more than 50 years of experience and feeling, I compared the HDMI cable I was using before with the Fiber Optic hdmi cable I bought. Not a numerical comparison of the results from the meter, but the new Fiber Optic hdmi cable I bought, which I can now feel with my eyes and ears, is much cleaner and the sound is particularly powerful for my ears with no loss across the entire range! At this point, it's not uncommon to find 16-foot high-end fiber optic HDMI cables that cost over $100. With this cable I bought for less than $30, I wondered why I needed this cable with such a luxurious reputation. I can feel the clear video image and lossless sound across all ranges of treble and bass, and there are no other conditions as long as there is no difficulty in installation. After all, it is my sense to enjoy the video screen or sound rather than the digital numbers displayed on the measuring device. I would like to give +++ to 5 stars.

Ordered 4 of these , 1 was to output the video from my receiver , the others were used for my PS5, Xbox series X and switch . Xbox is the only one that’s having where the screen goes blank . Another reviewer said the same thing also. Will order another brand to see if it works . Other than that it works fine with other devices

Obtained this after suffering 4K@60Hz intermittent signal drops (image and audio blank) on a 60 foot ATZEBE Fiber Optic HDMI Cable 60ft, Fiber HDMI Cable. This FIBBR 50 foot 8K@60 cable cured the signal drops. The ATZEBE is rated for 4K@60 and that was all being transmitted through it to a bedroom Vizio sound bar. An identical ATZEBE cable feeds my HT projectors, but somehow connection stability with a Vizio sound bar was not possible. This FIBBR 8K@60Hz cable fixed the dropouts. Also obtained a 25 foot FIBBR 8K@60 fiber optic to try fixing another intermittent connection. That one was a 12 foot run via copper "8k" cable carrying 4k 60 Hz from HDMI matrix switch to Hisense TV. Initially, got no connection negotiated, but after some EDID adjustements on the HDMI switch, a solid connection was achieved at 4k 60 Hz. So in two different situations a FIBBR 8K fiber optic cable achieved a stable connection where other cables failed. Definitely pleased.

If you are using a HDMI KVM from Level1 these absolutely resolved all the issues I was having with my display. They work wonderfully, small/thin cables and no more flashing screens or resolution issues. I purchased one then followed through replacing all the others, one at a time. I've gone from sceptic to believer. Edit : I was initially a believer and purchased 5 of these, but about 2 weeks in these cables simply stopped working. The screen would flicker on and off. I fought with them. I tried unplugging and reinserting them. I gave up and now they sit unused. Replaced with zeskit maya.
