Solve : Twisted Pair Cable help?

Answer»

I have a Q/A about Making Twisted Pair Cable??

When you STRIP the cable open you have 8. wires and you have to pair them up.
So you end up with 4. pairs of wires I get this.

But this is whare I need help every pair of wires you must Twist and then get the next pair of wires and Twist them.

This is sapost to keep the Data from getting crosed over.

But the whole cable that you did not cu open are the wires Twisted inside ?
And if not why??

PS...
I know I can buy a Twisted Pair Cable I am just a geek
ThanksThe twisted pairs are not twisted around each other in this picture

I think I know what you mean. Are you trying to make you're own lan cables?
If so, this is what I do.

I cut the desired length I need or want.
Make sure you add a few more feet so you can move your PC around when you want / need to.

I then strip back about 3 or 4 inches of the PLASTIC covering so I ahve all the wires removed.

You'll see that they're already twisted.

untwist the wires and then group then in this order.
Holding the wire in your fingers place the wires starting from the left and moving right

Orange / White
Orange
Green / White
Blue
Blue / White
Green
Brown / White
Brown

Make sure they're nice and straight and held firmly between your fingers and cut them so they're about 3/4 of an inch long sticking out of the outter plastic or at least just above your finger tips.

Take an RJ45 connector with the tab on the underneath slide it over the wires and slide the wires into the little slots firmly.

Holding it all securely take the RJ45 crimping tool and CRIMP the connector firmly.
Follow the instrcutions again for the other end.

It makes it much easier to test this if you have a Cable tester.... that takes some of the guess work out when you don't make a connection in the RJ45 or miss wire it.

i strongly recommend not making your own ethernet cable. why?

because ethernet cable (cat 5) is specifically designed and engineered for transferring data at a certain max speed. the diameter of the copper wire, the insulation around each copper wire, the insulation around the entire group of wires, and the varying degrees of twists around each pair all effect the max speed of the cable.

do not twist them more, when hooking up to an RJ45 connector or outlet, try to limit the amount that you untwist. as i stated earlier, they are twisted at varying degrees for a reason.I totally agree with Homer. If you making cables just for fun or for your own desire, cool... If it's for something in the server room.... Buy it.... when that SQL server LOSES the connection because your home made cable wasn't good......You don't want to stand in the VP's office and explain to him that you saved $4.00

But is a good practice to learn how to make your own cables and it actually does come in handy every once in awhile.

it seems i was not very clear, when i stated "i strongly recommend not making your own ethernet cable" i meant the actual cable. by all means it is fine to crimp on your own RJ45 connectors.
