CABLEDECONN Fiber 8K 4K DisplayPort Cable DP 1.4 HBR3 8K@60Hz 4K@144Hz High Speed 32.4Gbps Optical Fiber Slim and Flexible DP to DP Cable 10m 33ft

This review is for the 10 meter fiber optic cable.This cable does what it claims on the package and what you'd hope: It works just like a copper DisplayPort cable, except for longer, and thinner. I've found no limitations with it at all, no issues. It works in 3840x1600 8-bit @ 144Hz and 3840x1600 10-bit @120Hz both of which are right near the maximum speed DP HBR3 supports. It works with SDR mode and HDR mode. It works with Gsync over the entire frame rate of the display, including very low frame rates (like 10fps). When I lock my computer, the display goes to sleep, when I turn my computer off, the display goes to sleep.In other words, it works just like the copper cable it replaced. I haven't found any "gotchas" or cases that worked properly on a copper cable but don't on this. It just works.Price is good for what you get, in line with what it should cost. Fiber optic cable and lasers aren't expensive these days thanks to their widespread use in Ethernet. Don't think that if you are paying ore it is for better quality, you are just getting ripped off.

Ran great for a week before turning into a brick. (10m version) Was using 28.14 Gbit/s of the "rated" 32.4 Gbit/s and it overheated and completely stopped working after a week of 6 hours/day usage.

Edit: Just replaced my computer. My new graphics card is an RTX 3090 and SSD is Western Digital SN850. The cable now works perfectly up to 144hz in the Valve Index and has not caused any startup issues. I guess it was just a fluke with my old computer which had a GTX 1080 Ti.----This cable paired with the Cable Matters DisplayPort Repeater (ASIN: B07D949F59) is working with my Valve Index at least up to 120hz without any artifacts. 144hz looks almost like one eye draws faster than the other causing a smearing/shadow along the edges of everything while moving. Luckily I never saw much of a difference between 120hz and 144hz so 120 is fine with me. This cable did NOT work with the Cable Matters DisplayPort Coupler (ASIN: B00YFPM2CU).A strange issue worth noting is that my computer's boot drive disappears from the BIOS if this cable is plugged in prior to turning on. If I start my computer then plug in the cable after boot everything is fine. If I have the cable plugged in then turn on my computer it won't boot because it can't see my SSD. Tried a different video card and motherboard and the issue continued. I can't even begin the fathom why this happens but I've tried so many fiber optic display port cables without any success I'll live with it for now. If you also happen to have an Intel 750 SSD or other PCIe slot SSD be advised this cable may cause you grief.

2 weeks in with the 15m cable. First things, it is an optical cable it is fragile by nature I haven't broken the cable--but be warned (preliminary mark on the 'durability' score reflects this). One other thing to know, there are defined source and device ends on the cable, make sure to plug the cable in correctly--the cable is marked and the instructions in the box advise you of this.Now, it is an optical cable. So there are micro-light sources internal on the cable ends. They get warm to the touch, when the source device is powered on and sending signal. Time will tell how long they last (hence the 2 week caveat emptor at the beginning), early optical thunderbolt cables had problems in that regard. I've been running 3440x1440 at 10bit color 144Hz without issues.For people using high-resolution DisplayPort for monitors there isn't much in the way of long-range optical cabling and this product so far has been a winner.

I'm using the 10m cable so I can keep my computer in a cabinet rather than on my desk. No problems at all doing 5120x1440 @ 120hz, or 4k @ 60hz depending on which monitor I am connecting to. I did run into one brief issue where the screen would get intermittent bright lines, but the manufacturer replaced the cable and the new one has been perfect. Worth noting is that the connector is longer than regular dport cable connectors.

The cables works just like intended, I got three of these (10m) and the plan was to plug them all into my RTX3080-card, but I can only use output 1 and 3, as the housing of the plugs are too wide and there is not space to fit a plug in port 2.

TLDR: I ended up paying for three and getting 0 working cables.I purchased my first of these a year ago. With a 1440p ultrawide (3440x1440) it struggled to push the 144hz it should be capable of and would just display a blank screen until the refresh rate was decreased. After roughly 6 months the cable started to fail and started failing to push 120hz, then 90hz, and finally it wouldn’t reliably pass video at all. I contacted support and they quickly replaced it under warranty. However, the warranty replacement arrived faulty. When the computer resumed from sleep the screen would stay blank until I unplugged the cable and plugged it in again - even rebooting the computer was not enough. I verified that the problem was with the cable since it only happened with the fiber cable. I contacted them and got an exchange, but that arrived with the exact same problem. I contacted the company and they refused to honor the warranty and get me a working cable and told me to just buy another company’s cable. When I tried to return the cables they were lost in the post and I was charged for them despite no longer having the cables and them being faulty. So I am out the full price of the original, the warranty return, and the exchange for the warranty return (almost $200), and all I have is a single cable that wont even do 1080p 30 hz any more.

Mono directional cable. Great price for the product but found that after a full office day of working, the source side plug would be burning hot to the touch and signal would start intermittently dropping out to my display past the 7-8 hour mark.
