Here’s the solution to my deluxe problem. I have a lovely LG 55″ OLED tv, and my A/V equipment is about 30 feet away in a closet, due to my wife having successfully waged a campaign against wires a few years ago.
I wanted to view 4K and Dolby Vision from my spiffy new Apple TV 4K. Alas, my existing HDMI extender solution wasn’t even good for 4K/60, and forget the higher bit rates.
This cable delivers. It’s flexible enough that it was relatively easy to route it through walls, holes in floors, etc. It delivers the 18.2Gbps data rate you need for 4K Dolby Vision and 4K HDR10 4:2:2 content. The price was lower than 4K HDMI to ethernet solutions, and it actually works better (I learned that by spending $750 on an extender that won’t do the full data rate when transmitting Dolby Vision content due to the the color info is encoded).

I have the 10m Ruipro cable I have temporarily run the cable around the room so that I can give it a good run. Changed all of the Oppo settings so that it would run at max bandwidth and the Ruipro passed with flying colours. The final test for the first night was to pop in Billy Lynn’s Long Halftime Walk 4K UHD which runs at 60FPS and again the Ruipro had absolutely no issues.

Took a chance last April and ordered 50 ft HDMI with ethernet. Always had problems with devices connecting at UHD. Although they were marked as “certified for long distances” I had nothing but problems. Looking for solutions I found the Fiber cables. I struggled initially with the sticker shock but ultimately my desire to get good and consistent 4k/UHD into my OLED TV won over. Bought 4 and ran them across the room yesterday. What a difference. Everything works and not a screen flicker. You get what you pay for. Most reputable cable companies will not sell regular HDMI over 15 feet for a reason. If you are having problems but these. Work great.

I tested a bunch of cables, and this is the only cable above 15ft that supported 8K with the Denon 3700H receiver HDMI cable test albeit in only one direction. Surprisingly for short distances, my 5 year old Audioquest Pearl 6ft cables support 8K although there were no 8K back in the day, and they’re even bi-directional despite what AQ writes on them. However, when I tested the Cinnamon at 8m (26.25ft), and it didn’t pass the 8K test. So back to Ruipro, it was the only long cable that supported 8K but only in one direction.
PS: if you connect this to AppleTV 4K make sure you use the USB/HDMI power dongle that comes with the package, otherwise Apple TV cannot show Dolby Vision or HDR content.

So far so good! Based on the reviews prior to purchasing, I was confident that this product would meet my needs. I have a 30′ run in my home theater going through a conduit from screen to projector. And because of the length a normal HDMI was failing to carry the native 4K signal successfully. Fiber was the best option based on research and I had narrowed down my options to either the RUIPRO or Celerity options. The consistent feedback was that the RUIPRO product; although cheaper, was more consistent with performance and dependability. Now that I have taken delivery on two of the 10M cables I can confirm that they work flawlessly. Per the companies recommendation I hooked up both cables prior to installation to ensure that they worked with all of my sources, once performance/connection was confirmed I took me about 30 minutes to gently/patiently fish the cables up through my conduit – replacing the older two HDMI runs. Reconnected to devices and again, no issues. I have ran multiple sources through them using an array of media (ie. UHD BluRays, 4K MKV files, etc.) and have yet to have a failed experience. So I can definitely recommend this product to anyone who has runs exceeding the normal 6′ length that HDMI struggle to perform with when pushing 4K+ feeds.

I’m running this to a Samsung CHG70, and there’s no discernable lag and the image is crisp and fluid. HDR 144Hz @2560×1440 works correctly, driven by either a 1080 Ti or Radeon VII. I’m leaving this review because if you’re in a predicament like I was, this cable will do the job; take the leap, Amazon has your back either way.

Initially, the Radeon VII couldn’t sync with the monitor, but restarting and switching ports fixed that. I’m pretty sure it was because it was trying to output 10bit RGB full, which is too much bandwidth for the DP1.2 spec anyway. I also ran this with A Samsung CRG50, and had no issues whatsoever @144Hz, 1920×1080.

Do note this is an active optical cable, this means it draws power from the source device, but this is allowed in the DP spec, so as long as the source is DP compliant, it should work (this may also explain the initial weirdness with the CHG70). It is also directional (source and display sides are labeled).
