Hi!

I have a device that requires an Ethernet cable. It comes supplied with a 1m cable but I need it to be 2m to reach the shelf.

So, on the cable it says TIA/EIA-568B.2 CAT.5E PATCH CABLE.

I looked online to see if I could get a 2m one, but they are all CAT 7, CAT8... etc. Russell has an old one for his xbox but that says something different again (cat 2, or 3, can’t remember...) so are these all different things? Does it have to say .5E, or can it be a higher number, or... something else :)

the higher the cat number the better it is, (it can handle faster data connections, wake on lan, video over ethernet, etc) Anything above CAT5 should be fine.

Quote:
Class F channel and Category 7 cable are backward compatible with Class D/Category 5e and Class E/Category 6. Class F features even stricter specifications for crosstalk and system noise than Class E. To achieve this, shielding was added for individual wire pairs and the cable as a whole. Unshielded cables rely on the quality of the twists to protect from EMI. This involves a tight twist and carefully controlled design. Cables with individual shielding per pair such as category 7 rely mostly on the shield and therefore have pairs with longer twists.


Just to show I didn't make it up: https://en.wikipedia.org/wiki/ISO/IEC_11801#CAT7

Not better in all ways - cat6 has a larger bend radius than cat5e, so you can't turn it round corners as easily. I think I've got that right, been a while.

Also more expensive, so not better if you are on a budget

Correct. Bloody waste of time in an office when you have tricky corners to get around to people's desks.

It's still the better product, though.
