Like the picture shows, I think he was just untwisting the very end. Upon reading the headline, I was also concerned about the extent of untwisting. But, I think the main length of the cable is still twisted, which is done to make the pairs resilient to induced noise. Untwisting the entire length of a Cat 6 cable would defeat this signal integrity mechanism and potentially make it incapable of hitting the rated speeds. Reply
bill001g The title is misleading. What he is doing is installing infrastructure cables not making 50000 patch cables. The time it takes to untwist a few wires is nothing compared to hauling a ladder around and doing the setup. Maybe he does 100 cables into a patch panel not 50,000 at one time The guys I used to watch install patch panels did it all by hand and were extremely fast. The machine he is trying to copy is what they use when they make patch cables in a factory sitting at a table. Reply
AmirTHforum Why doesn't anyone comment or complain about the obvious problem here? And that is the archaic way we connect Ethernet. I don’t care when Ethernet or the physical connection was invented, but that must be the worst design ever. And why hasn’t it been updated? Am I wrong about this? Reply

And why hasn’t it been updated? I guess you're talking about the RJ-45 connector? If so, I'd agree that it's not optimal. I can't count how many times I've seen Ethernet connectors with a broken latch. I've even had a batch where latch seemingly broke through simple plastic aging, because a bunch of my cables had latches with zero springiness and I'm really careful with my cables so I know that wasn't due to them getting snagged on something or being abused. What I found disturbing about that is how at least one of these cables seemingly required the pressure exerted by the latch for the metal fingers to make good contact. Because, even though the cable was fully inserted, I found that the connection was unstable. I think two factors keep RJ-45 in use: backwards compatibility and the relative ease of attaching connectors after running bare cable through a conduit. I'm not an expert on connectors, but it seems to me that anything aiming to displace RJ-45 would need to be similarly cheap & easy for installers to crimp on. I don't know if there's anything which meets those objectives that's significantly better than RJ-45. As for the rest of the cable, shielded twisted-pair seems to be pretty much the gold standard in copper cable technologies, which is what the highest-grade Ethernet cables use. Reply

Where I worked they had a seeming simple project of swapping out a rack of switches with newer models. This had been sitting untouched and working fine for 5yrs. About 200 cables to unplug and plug back in was the theory. The plastic ends on those cables were so brittle that we had plastic tabs all over the floor. That room ran kinda warm so likely helped damage the plastic. So now a 1 hr project took all day because all new patch cable had to be found and run. Goes back to if it isn't broke don't fix it rule i guess. Reply
