Soldering/splicing wires sucks

[ChadTower]

Of course it might exist, but it's far less common than with solid core installation wire.

While that's true, he is the one complaining about how much soldering stranded wires sucks.  Sometimes you just have to evaluate what you're using and maybe make a run to the store for 10' of a different cable.

BTW what I don't understand is is how you get crosstalk in the Cat6 cable, but not in the original cable. Is that because of the length that you are trying to add or did they add some form of shielding inside the original cable?

[ChadTower]

He is getting it in 5e.  I assume it's because he unwrapped the pairs when he spliced them and also because he is running power over a line specced for data.  More current = greater magnetic field, and when you add in the unwrapping, there is nothing protecting those individual inner lines from interference. 

That is of course just my theory but it is why it was suggested earlier that he split the power out separately.

I thought shmokes said he had cat 6.

Either way, my question was why the original cable does not suffer from crosstalk.

[shmokes]

Yeah, the original cable, as I say, has smaller gauge wires for all but the power (26 gauge perhaps) and larger for the power wires (22 maybe -- I actually thought the gauges were always even numbers).  None of the wires are twisted, and the overall thickness of the cable is maybe 2/3 a typical Cat 5e patch cord.  The wires have been untwisted in three places: at my splice, at the male RJ45 connector, and at the jack.  I've added about 5-6 feet of length to it.  I probably could have got away with 3-4 feet.  I shouldn't have pushed it, but I wanted to be safe.  I.e., I didn't want to have to start all over again.  Look where that got me.   

[patrickl]

Did you make sure that the doubled up power wires are a twisted pair together? Maybe you twisted the power cables around the signal wires?

Twisting wires only works against interference coming from outside the twisted pair (and then only to distribute the interference over both wires instead of on one wire)

[shmokes]

Yeah . . . at first I wasn't going to, just to preserve the color coding.  But I ditched that idea and made the power wires green/white-green and orange/white-orange.
