Review on FeizLink 8K HDMI 2.1 Fiber Cable 50ft - 4K 120Hz, 8K 60Hz, 48Gbps, Dynamic HDR10, eARC, HDCP 2.2 - Compatible with RTX 3080, RTX 3090, Xbox Series X, PS5, LG C9, Samsung Q90T, TCL, Sony by Joe Glass

I have a couple of gaming PCs in my basement (best place for hot and loud power hogs) and I use them to connect HDMI to 4K TVs upstairs and this cable manufacture it just such a run. The cable offers an excellent picture, great sound and is immune to interference. This is a real blessing as I also route various power, network and analog signals down the cable and the fiber doesn't care about EMI. Be sure to plug the source cable end into the source and the display end into the display (as an active cable, they're not interchangeable) and the rest works. My requirements haven't tested ARC/eARC so not much to report here. If you need it, read the other reviews (some fiber doesn't handle this aspect of the connection).
