[CAT6] Pick the right cable for your project
Cat7 cable is officially a lie because only two of the three groups needed to be approved for that claim. When people use Cat5e at 10 gigahertz speeds, they can't promise it works every time. Even Cat6 might work up to fifty meters on some brands but drop to forty meters on others. If you are setting something up for professional use, you need to trust your own tests or experts, not just what people post online. A Cat5e cable is built to handle the full one hundred meter distance at gigabit speeds—that's exactly what the certification says it can do. Maybe someone is selling fake cables if they don't make that long run. I've used things like Cat5e at 10 gigahertz before, but my personal experience doesn't count; the standard actually requires a Cat6a cable to guarantee the work will happen unless you have that specific one.
By that logic, Cat6 wires don't even exist because it was never officially approved. EIA is really slow at making changes; they only went ahead with Cat6A because the vendor created Cat7 and ISO said yes to it. The reason EIA took so long is because they were fighting for "fiber all the way to your wall," pushing everyone away from copper just in case, rather than just speeding up existing copper stuff. It's funny how you shifted your argument from saying standards don't matter to saying that actually, standards DO matter. Wiring all four pairs follows an ISO standard so you can keep those high speeds over the full distance. I was showing you why things sometimes look fine even when they shouldn't. The cables themselves have no active part talking back and forth; instead, the adapters start with the highest speed possible and slowly slow down until a stable link is made. Shorter wires let higher frequencies pass, so you can get 500mhz on a tiny 3-meter Cat5e cable, but that drops to just 100mhz when it's 100 meters long.
