We'll assume you're ok with this, but you can opt-out if you wish. T568A vs T568B : Comment Choisir ? As an example, we need to copy data from one computer to another, but the two computers don’t have access to a switch for help with this process. The pairs in these cables consist of four colors (blue, orange, green and brown), with each pair includes a solid-colored wire twisted with a wire of the same color, with white stripes.
No solo puede coincidir con el antiguo código de color del 258A de AT&T, sino que se adapta también a los requisitos actuales y futuros, así como a versiones anteriores con código USOC.Los cables de red directos y cruzados se conectan de forma diferente entre sí. If you look closely, you can see that the majority of the distinctions between the two are not in the color, but in the assignment of the pins. It can not only match the AT&T’s old 258A color code but accommodates for current and future requirement, as well as backward compatible with USOC. So, what’s the main difference between T568A and T568B? In all situations, one standard should be adopted and used to avoid a mixed environment. The same is true for the cabling in the wall and the patch panel where they all terminate.Now for other applications, we may need to connect a computer direct to another computer or a host-to-host connection. These two sets are swapped in the cable. Lorsque vous raccordez un câble réseau, vous devez disposer les câbles colorés dans le bon ordre. T568A vs T568B: Which Do You Prefer? Quelle est donc la principale différence entre la norme T568A et le T568B ? En termes de T568A vs T568B, ce sont deux normes de câblage qui sont utilisées pour spécifier la disposition. This allows the computer to communicate with other devices on the local area network.
A cross-over cable can be used to accomplish the same task without the need for the in-between hardware. Both T568A and T568B provide wiring schemes for terminating twisted-pair copper network cable to 8-position RJ45 jacks and connectors. Wie in der Abbildung unten dargestellt, besteht der Hauptunterschied zwischen diesen beiden Standards in der Position der orangefarbenen und grünen Drahtpaare. These two computers need to use a cross-over cable.In a standard network, a switch or router is used as an in-between device that can cross the data connections so the receiving computer can use the data. There are subtle differences between T568A and T568B, but this doesn’t mean they shouldn’t be addressed. The only real difference between these two pin-to-pair assignments are the green and orange pairs. Both standards are used with 10/100BaseT cable. share. Como se muestra en la siguiente imagen, la principal diferencia entre estos dos estándares es la posición de los pares de cables naranja y verde, lo cual no es solo un cambio de color, por supuesto. Lorsque vous raccordez un câble réseau, vous devez disposer les câbles colorés dans le bon ordre.
Entonces, ¿cuál es la principal diferencia entre los estándares T568A y T568B? También habrá factores de compatibilidad, lo cual deberá influenciar en su decisión de un esquema de cables RJ45.Por lo general, los cables directos se utilizan principalmente para conectar dispositivos diferentes. For example, a computer plugged into a wall panel uses the standard cable configured with either T568A or T568B termination. In most networks, cross-over cables are not needed as they have a specific use.Cables can be made with either termination standards and in most instances will work. Each one consists of solid colored wire and a strip of the same color. En gardant à l'esprit que T568B est le format le plus utilisé pour les réseaux, vous êtes techniquement libre de choisir le format de câblage que vous préférez lorsque vous entreprenez la construction d'un nouveau réseau.

Based on TIA/EIA-568-B.1-2001, the T568A and T568B wiring schemes define the pinout, or order of connections, for wires in eight-pin modular connector plugs and jacks. Then when it comes to the cross-over cable, its only needed in host-to-host situations so those cables are not used often. Was ist also der Hauptunterschied zwischen T568A und T568B? Of course, this is not only a single color change. Los otros dos pares de cables (de color marrón y azul) se utilizan para otra aplicación de red Ethernet o para conexiones telefónicas. If you are just getting started on your network, or if you need to rewire some things, trying to determine what standard you should use or what type of cable to purchase can be a daunting. And also, it offers backward compatibility with one-pair USOC wiring schemes.. Now comes the question, can T568A and T568B be mated? I believe this is why it’s so confusing to most, because using either of these standards gets the same result; a working patch cable.
