CAT5 is typically flat, which works well for compact patch cables. Most often it appears as twisted pairs inside a round sheath for standard cabling needs. CAT6, however, is designed with a tighter twist and a plastic core to help minimize interference between signals.
Flat cables are still twisted pair, just made differently and usually use the smallest gauge possible. I have a solid 10Gbit connection over a 7m flat cable that seemed too thin to support it. I ended up buying a standard CAT7 cable, which only supports up to 5Gbit.
The staggered pin layout seen in the CAT6 end picture is common across various brands. I've replaced many CAT5e units, and the pin endings vary depending on the supplier available that day.
It's fascinating to learn about this, since I've only encountered brief, straight cables before. They appeared completely flat without any bends. Looking into more details, I understand flat cables can be arranged in different setups, which is great!
It must always be twisted if it's labeled as Ethernet, but I only verified this after the retention lug detached from my end, so I removed it to check if a replacement was possible. The strands were extremely thin, making replacement unlikely, though I could still observe the twists.
