wiring a rj11 plug

Hi I'm making a home-made cable for master socket to router. I have a c?rimp tool, 2 rj11 plugs and a length of cw1308 cable.

My question is with the 4 connectors on the plug which colour wire goes in which hole? And presumably they need to be identical on the plugs at each end?

If your CW1308 has four wires..

Then using a twisted i.e.
Blue with white stripe
White with blue stripe

Connect these to the two centre pins. The other pair you simply spread out and connect on the outer pins.

And the same at both ends.

thank you

the forum from which that second picture is taken appears to say the image is incorrect

The crossed centre pair should not matter really, but my usual habit on RJ11 leads is to not cross them over at all,
Blue with white stripe goes to the exact same pin number at the other end

So do what I said originally and you should be fine. The note working in that thread is probably down to what looks like the sort of extension cable to avoid these days.

If doing a few crimps regularly then at a basic cable tester is worth considering. A good few times when putting crimps on cables in dark dank corners I have messed up and testers can save time.

Thanks for all the help. What's the best cable for making a lead from router to Openreach socket - and where do I get it?

In the OP you said you had the cable

No idea how much they need but

Is 10 metre of cable 20m and 30m are only fractionally more expensive.

I have something that calls itself cw1308 - but I've no idea if it's really any good - so I was wondering where to get high quality cable of the type Openreach might use. My internet connection is ropey - but BT can find nothing wrong so I'm trying to find an optimal set-up at home.

Thanks. I'm going to try some "CW1308 Black External 2 Pair Telephone Cable.SOLID COPPER CONDUCTORS" from ebay.

As Andrew has said, worth making up a test piece for your home-produced cable.

An easy way is to get hold of two RJ11 SOCKETs

For one socket, with six short lengths of wire, connect a single wire to each socket pin, the other end of the wire being "free".

For the other socket, using three short wires, connect the following pins together

Looped Socket
1 to 6
2 to 5
3 to 4

----------------------

When you have made your (intended) working cable,

Insert one of the RJ11 Plugs in to the looped socket.

Insert the other RJ 11 Plug in to the other socket.


With a Continuity Tester, first ensure that you get continuity

from Wire 1 to Wire 6

from Wire 2 to Wire 5

from Wire 3 to Wire 4



After that, check that you do NOT get CONTINUITY between wires 1 and 2, wires 2 and 3; and (very unlikely) wires 1 and 3.

I've done such tests many times!

Aren't there 2 pairs - 4 connections? Inner and outer?

RJ11 plugs support 6 wires, but generally are only wired with 4 or even just two used.

NOTE:

External grade should only be used outside a property with a very short length inside, due to the UV proofing means if the cable is involved in a house fire giving off toxic fumes.

I may be confusing with Ethernet cables; but the general method is the same; and can be used in many situations.

Isn't this more to do with the sheath of the cable rather than it being external cable? There's a lot of PVC and PE covered wiring in houses and not much LSZH imo.

Yes, it is the sheath that is the problem when used internally.

So if external grade cable with a LSZH sheath is chosen, there shouldn't be a problem?
