The bandwidth of Cat8 is 2000MHz. Cat5e is way down at 100MHz (as a minimum allowable).

FWIW that clearly is twisted pair.
Kenable wouldn't be on my list of quality suppliers. Show me a flat cable from a manufacturer like Excel and I'll take it seriously.
BTW what's the use case for a flat Cat8 cable? I doubt anyone who's buying those cables it sticking 40GbE through it.

I like Kenable. They have REALLY cheap EZ-RJ45 plugs. And I think flat is a sales/marketing thing. Like those ultra-thin patch cables.
thats all i saw in the pic here have a look:
Sorry - I should have retracted that post. I was talking crap from a position of ignorance. Having done 5 minutes reading on cables I can see that there is part of the specification (just as with wireless) where bandwith is altered by the frequency that you can turn the signal on and off at. Again, thanks to @bremen1874 for the gentle education.
Why's that? I've used Kenable solid core cat6 outdoor cable with no issues as a good compromise between fricking thick hard to use/install cable and very flexible inferior CCA cable. I've never had it not deliver gigabit even over long runs with harsh right angle twists. It terminates fine and the internal twisted pair colourings do not fade. I don't have any 10gb equipment to test with an likely won't do for years as I don't have a usage case for anything above giga.
It does feel a bit 'thin' though compared to Excel or BT Cat6. I only buy it because they make a white external grade CAT6 and they have external grade CAT5e in several different colours which other cable suppliers don't have. And the cheap EZ-RJ45's of course.
I dislike using anything more rigid or thicker to be honest as it's harder to clip to walls and starts to look unsightly requiring bigger cable clips. Becomes harder to go round wall corners without either kinking the cable or having a wide hang with an air gap. But yeah...Kenable has been fine for me. Ask me again after 10 summers if it still works. I bet it will.

I don't disagree. It's just a perceived quality thing. If the first cable I was trained on was Excel/BT branded from Cable Monkey and it's 7.5mm diameter with a THICK cable spine if you give me the Kenable stuff that is under 7mm diameter and basically hasn't really got a cable spine then I'm going to see where money has been saved and part of me just goes 'cheap'.
As you say, it works just fine with one exception. I find it's more susceptible to nicks in the outer sheath if I'm rough when I pull it. The obvious solution to that is not to be rough with it when I pull it. And you can't argue with the price.
some people say you cant do 90 degree bends on these cables since its like a railway track and if the packets hit a corner at gigabit speeds they can "derail" as such . lol
Is that why? didn't know that. Thanks for the education
not me that made that claim.
Dunno avalon mentioned it was.
Well, Avalon knows what (s)he’s on about so it probably is correct. You could understand how you could break the outer sheath on the conductors and the packets would just spill out and keep going in a straight line. I think it’s called conservation of momentum or something.
No not the avalon guy on here but avalon networks uk who i spoke with and said that their cat8 cables are recommended since with other brand cables they send the packets via skin effect on the surface of the conductor and like a train can derail if the track hits a 90 degree sharp bend. They claimed with their own cat8 cables the packets travel through the conductor like a tunnel and can be bent any way, the packet has no where to go other than out the other end of the cable.
