On a straight through cable, the wired pins match.
#BEST WAY TO SPLICE 2 CAT 5 WIRES TOGETHER PATCH#
This type of cable is also sometimes called a patch cable and is an alternative to wireless connections where one or more computers access a router through a wireless signal. If you are unsure of which to use, choose 568B.Ī straight through cable is a type of twisted pair cable that is used in local area networks to connect a computer to a network hub such as a router. T568B has surpassed 568A and is seen as the default wiring scheme for twisted pair structured cabling. The first is the T568A wiring standard and the second is T568B.
There are two standards recognized by ANSI, TIA and EIA for wiring Ethernet cables.
A pinout is a specific arrangement of wires that dictate how the connector is terminated. Then, what’s the difference between straight through vs crossover cable? Read through this post to find the answer.Ī RJ45 connector is a modular 8 position, 8 pin connector used for terminating Cat5e patch cable or Cat6 cable. Crossover Ethernet cable is more commonly used to connect a computer to a computer and may be a little harder to find since they aren’t used nearly as much as straight through Ethernet cable. They are most likely what you will find when you go to your local computer store and buy a patch cable. The straight through is the most common type and is used to connect computers to hubs or switches. The longevity and reliability of my cars is evidence enough that what I'm doing is just fine.Ethernet cables can be wired as straight through or crossover. So I'll keep using them, but then I'll keep doing things that other people don't agree with anyway. I have repaired enough butt connector failures to avoid them and have yet to repair a single solder connection, but it's probably because none of them are 19 years old now. To me, a butt joint crimp connector is like a tire plug, good enough for now but not the proper way to make a repair. "Good enough" is good enough and will outlast the anticipated lifespan of the car, but many of us drive them well beyond it. VW's (and most every other car manufacturer's) mission is to produce cars at the fastest rate they can while still maintaining reliability (that's another arguable topic), so it makes absolute sense they wouldn't wait for solder to heat, cool, and be consistent. This issue can mostly be mitigated by using a better wire stripper, like a thermal wire stripper.Ĭlick to expand.That's due to the process involved in the manufacture and has nothing to do with longevity.Īs evidence I offer you this factory crimped (or rather mashed) jumble of wires found on the B4 (yes, I know they're grounds). This leads to a stiff wire that ends at a weak spot and this creates a point of failure. Then when you solder the wires, capillary action causes the solder to wick up the wires until it reaches that nicked spot where it stops. These blades invariably nick the wires right at the point where the insulation ends. Almost all common (read: cheap) wire strippers use sharp blades to cut into the insulation before pulling it off. The issue is really the way in which the wires were stripped before the connection was made. There is a potential issue with soldered connections breaking at the end of the solder joint, but this issue is usually not actually caused by the soldering itself. However, one important point (IMHO) has been missed. Soldering and butt (crimp) connections both make for good electrical connection and both have advantages and disadvantages over the other. I'm just yammering on again.Ĭlick to expand.I have been in the electronic manufacturing and service industry for over 40 years. To me this seems better than the straight line crimp. As I started to think about this more though, it seems that solder will wick up the wires to different points so the end of the solder joint actually tapers off. In my mind, this is a recipe for breakage (without a proper strain relief).īut soldering also gives a place where it goes from flexible wires to the stiff soldered part, which gives a point for breakage as well, it just doesn't crush the wires. not only is it crushing them, but it is crushing them in a straight line. With a crimped connection, you have the metal sleeve that is crimped and is crushing some of the wires. soldering, one thing that always bothers me is wire breakage at the end of the solder or at the crimp. In his defense, he is a customer of mine, and was here doing me a favor, so I couldn't really expect a detailed explanation. I don't quite understand it, but at least I know that there is a kernel of truth in what he said, but he skipped some details. Abacus and tadawson had great answers to my question.
