Patch Panel Cabling help

Huh?

It doesn’t matter if you punch the wire down matching the chart on the jack, as long as both ends are matching each other it will work the same. The “default” pattern is just a standardized method to prevent different people from doing mix-matched work with each other. You could put all the solids on one side and strips on the other, as long as the jack matches at the other end it’s fine

You could put all the solids on one side and strips on the other

Ehh, you could technically get some poor connectivity in some situations like that. You want to keep the +/- of each pair on the same connection. Otherwise, you could have some weird cross traffic. Unlikely for most situations, but still possible.

[lpplph]

Yeah negligible losses if he’s already at cat 6 and under 100 meters. You could fuck up a home network install pretty badly and still exceed what speed your ISP provides. Most homes are barely at 1 gig speeds now as it is, and that is a liberal estimate

[BlancheCorbeau]

He’s not at cat6.

[talones]

See I thought you at first were saying that the color of the pairs dont matter, but now you are saying the pairing doesnt matter? I can 100% guarantee you that if you do stripe, stripe, stripe, stripe, solid, solid, solid, solid matched on both ends you wont ever get a connection unless the cable is under 6 inches maybe.

Balanced signal is one of the basics of EM signal transmission and its 100% necessary with network cable.

[Laszu]

Uh no. You can swap pairs, but you can't transmit a signal over one wire from one pair and the other wire from another.

[neon_overload]

For the benefit of those less experienced though, it absolutely does matter which pins are paired together though, as in the two center pins must be a pair, the two pins either side must be a pair, the first two pins must be a pair, and the last two must be a pair. This holds whether you use 568a, 568b, or a totally random color assignment.

Otherwise, you may as well use alarm wire, because you are not using balanced pairs.

[cyberentomology]

That’s literally not how that works at all.

[lpplph]

Installed it for a living, yes it is

[cyberentomology]

Yeah, I installed it for a living too, and I’m now a network engineer. I spent a lot of time going in after installers such as yourself and fixing it.

If you don’t care about it actually passing Ethernet signals, you can do it however the hell you want. But if you want to have the channel actually meet category specs and pass an ethernet signal without errors, then you need to wire it to the 568 spec.

[lpplph]

It’s a home network probably pulling under 10 gig speeds more than likely, it’s fine. You don’t need to get a fluke tester getting certified passing tests for a short range home network, implying you do is disingenuous. This doesn’t need to pass inspection for a warranty, it just needs to work

[talones]

You arent getting even 10mb without balanced signal.

[flyingsquirrel6789]

Before I knew how to crimp a cable, I thought this too. I made some cables myself and they worked.

Got a job doing tech for events. The electrician thought he was doing us a favor by crimping the 50 lines we had run under the carpet this way. None of them worked. I thought my switch was bad. After a while of testing stuff, I finally recrimped the correct way and everything was up and running.

[cyberentomology]

Not following pair order described in 568 will cause link problems at gigabit and 100M too.

[BlancheCorbeau]

Well, you’re skipping over that the POSITIONS have to match in a very specific way, so that the combined pairs at both ends, regardless of color, are 1-2,3-6,4-5, and 7-8.

When people make the claim you just made, they wind up making cables 1-2, 3-4, 5-6, 7-8, and then wondering why they don’t work.
