Cat 8 cable?

Cyber-Mav · 2 Feb 2021 at 22:37

Anyone using cat 8 or even 7 cable? Anyone gone from lesser cable like 6a or 6 to 7 or 8 and saw a difference?
Now im not saying this from a home gigabit lan lan setup, but from anything else or situations that have benefitted from it.
Maybe someone ran a 200mtr run of it for 10gig speed or something?
Just more out of curiosity to find out in what type of situation it was of benefit.

Iv read of success stories of cat 5e doing 10gig so does that mean its possible for 40gig to be done by cat6a or is that 8 territory?

Optical fiber should not be affected by emi etc so doesnt need shielding like copper (or cca lol) so can run next to electric motors etc is that correct?

Whats holding back fiber optic? Is it the kit to convert light signals back to electronic signals?

Iv seen some pics of cut open cat6a and cat8 cable and both look very similar. Visually i can't see what the upgrades were.
Cat5e to 6a you can easily see the multiple shielding layers.

iv seen flat cat8 cables. how do those pass spec since they are flat i doubt they would be twisted inside?

Where? Amazon? Just more mislabeled fakery for the gullable.

many shops and one large networking and cable supplier too. shady i guess but its rated 2000mhz so cant say anything without testing it a proving it wrong.

2000MHz - like 2GHz? What does that refer to exactly? s an antenna that would pick up the low-end of most people's front door bells if it was long enough. Or do you mean 2000Mbps? In which case most CAT5e can do that.

thats all i saw in the pic here have a look:

i dunno about flat cable uses, do people just run it under the carpet?

harsh right angle twists.

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.

Is it not true then?

Dunno avalon mentioned it was.

Cyber-Mav · 3 Feb 2021 at 21:29

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.
I was like :eek:

ok so browsing aliexpress i came across cat 9 cable. whats the benefits of that? google says its not a standard.

Heh - Kenable are OK if you want something cheap and cheerful which isn't a complete lottery quality wise for something not too serious. I wouldn't want to use them in commercial application however.

Whats good brand to get and where from?

Cyber-Mav · 4 Feb 2021 at 11:30

hmm, usually copper is copper like cheapo speaker cable vs expensive ones. as long as conductor size and material is the same performance should be equal. im guessing with network cables the outer jacket quality can vary the most. but then again iv had ubiquiti tough cable fail before due to jacket splitting over time and water getting in.

Excel is nice but there’s really nothing wrong with Kenable.

yep just avoid cca for long runs or poe, but i can see why people go for it. 50 meter of cat5e outdoor cca for less than a fiver has many people sold i guess. haha

might cost £1 more than other cable

If the other cable costs 50p then 1 quid more is triple the price :eek:

Cyber-Mav · 4 Feb 2021 at 13:13

nickf23 said:
EEERM that would be double not triple .

how? 50p + £1 = £1.50p

so how is going from 50p to £1.50p a doubling?

My only idea was that it is like comparing a 2 lane motorway with a 5 lane motorway, you cant go any faster than 70mph but on the 5 lane you can get MORE there at that speed ?

so which cable is this that gives you more than the 4 pairs of regular ethernet?

The kenable cat6 I have may be better than the above "cheap and cheerful" some people talk of. The Kenable I have has an internal spline, internal pull thread and is black outdoor UV rated. It's quite hard to bend at a tight radius or you can damage the internal spline. It's solid copper core and apparently 23awg. It's about £45 for 100m.

looking at the excel brand cable cat6, i noticed in the pics it doesnt have that crosstalk divider spline going down the middle. why is excel rated as good quality then?
