How to wire this cable to cat6

Cyrus

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

Get a multimeter and run a continuity test on on each wire to the end with the plug and you should find what order the wires are in.

Not Ethernet cable. 5 Pair External Telephone Cable Black
Ethernet cable is 4(four) TWISTED pairs, not 5 as yours.

Sorry that sounds good but what do I need and how do I do that ?

Read second link or google why pairs are twisted

Where technically it will work , crosstalk will kill your network.

At 100Mb or less though most likely.



Sparks are always doing things like that.

I'd say the fitter just used pins 1 2 3 and 6. Have a close look at the RJ 45 ( the internet plug)at the other end

Did you check the rest of the cabling?

Skerries

They are in pairs it’s just they don’t be twisted very tight together and it can be difficult to tell generally you will have one white with each main colour blue orange green brown and grey.

I have no rewired it as a Jack and it works fine albeit maxed at 100mb presume I have accidentally put the pairs in the correct order

If I now wire a plug using the same config it should work right ?

I'd be getting the electrician back to do the job properly myself.

Cyrus

Yes will be getting him back to put the proper cable in

This is the correct answer. That cable may have "worked", but you've no assurance that a change in equipment or other environmental changes won't cause problems.

Failing that, I'd terminate it to a punchdown wall keystone and use a network tester that shows each pin to see if I got lucky, if not it's easy enough to swap them around. Inspect the other end, if your sparks thought cable that would suffice for network, he probably didn't follow the 568b standard which the keystone would be marked for.

When done you can pop it in a wallplate and plug your equipment in with a premade cable.
