Network cabling query

[cyrusir]

I had an ethernet cable run to a garden office. I needed to take the jack end off to put a plug on as I wanted to fit a ubiquiti in wall AP

However when I snipped the end of it off it looks like the cables aren’t in twisted pairs and the white ones are just plain white with no other colour (there is also a spare grey and a spare white cable)

How can I know which white corresponds with which other colour ?

It works so there must be a way

Are you sure they’re plain white. There should be a thin stripe in one of the other colours, not always obvious at first glance.
If really no marking you can buy cable testers for ~£10.

or use a multimeter. Can't imagine them not having the markings on them.

Multimeter won't work if one end is in one room and the other elsewhere!

of course it will flower. He has the ability to make the ends off. Even if there's no colours on the whites I'd have them paired up in 10 seconds and both ends made off in another 30 seconds.

Make the ends off?

re crimp them/terminate them.

I'm afraid to say that if you have a 10 core/5pair cable with a slate/white pair then you don't have an Ethernet type CAT5/6 cable. The cable you have is a general data/control cable with IEC colored cores:

The twist is very loose (about 2 twists per foot) so you may need to take off quite a bit of the jacket to identify the pairs.

You say it works & it might well do so but I'd suspect you will struggle to get decent consistent speeds. You might need to think about replacing it.

^ I think you are correct.

Luckily CAT6 cable is cheap and you could use the old cable as a draw wire.

Yes correct the electrician charged me for cat 6 and fitted this

the good news is that I have identified the pairs and also it seems to hold up at 100mb but I’ll be getting them back to replace it

thanks for all help
