AX11000, Cat 8 cable, and Ethernet switches?
AX11000, Cat 8 cable, and Ethernet switches?
I understand your observation, but the switch models don’t matter much since in all my tests—especially when avoiding the 2.5G port—I still reached only up to 100Mbps. It seems the cable might be faulty or the router could be the issue. I’m planning another test using the ISP’s router with the Cat8 cable to check for differences, but it would likely point back to the cable problem.
Cat 6 cable has been shipped, checked, and put in place. It functions properly with the switch and connections reaching my desktop, work laptop, and satellite STB.
A few of these highly rated cables seem questionable at best. My setup has a CAT7a that supports up to 5Gbit, while a CAT6 flat cable handles 10Gbit well. It’s unclear why this discrepancy exists—maybe it’s due to differences in cable capacitance affecting certain modulation types. Regardless, it’s evident some cables don’t fully meet their advertised performance.
I’ve retained the cable because it could be valuable later if I require 30m of Cat8 someday. Right now, since Cat6 perfectly meets my needs, I’ll keep the existing configuration for now.
The problem lies with Cat 7 being only ISO certified while lacking TIA certification, which is crucial for Ethernet standards. The TIA certification determines the actual performance capabilities of cables. Many Cat 7 products aren’t up to the required quality for their labeled specifications. In contrast, Cat 8 comes with TIA certification and is suitable for short-distance applications in data centers. Honestly, I’ve never understood why people insist on using the most expensive Ethernet cables. Cat 6a supports up to 10 Gbps over 100 meters, but if you need more, fiber is the better option.
