Ethernet crossover cables are used to connect two devices directly to each other without having to use a switch or hub. These cables are typically used to connect two computers, or to connect a computer directly to a printer or other peripheral device. In this article, we will discuss the wiring diagram for an Ethernet crossover cable, as well as frequently asked questions related to these cables.
What is an Ethernet Crossover Cable?
An Ethernet crossover cable is a type of Ethernet cable that is used to connect two devices directly to each other, without the need for a network switch or hub. This type of cable is used primarily for peer-to-peer networking, and is commonly used to connect two computers, or to connect a computer to a printer or other peripheral device.
The primary difference between an Ethernet crossover cable and a standard Ethernet cable is the way in which the wires are connected. In a standard Ethernet cable, the wires are connected in a specific order, while in a crossover cable, the wires are crossed over so that certain wires are connected to different pins on each end of the cable.
Ethernet Crossover Cable Wiring Diagram
The wiring diagram for an Ethernet crossover cable is relatively simple, and involves crossing over certain wires so that the devices can communicate with each other directly. The wiring diagram for an Ethernet crossover cable is as follows:
| Wire Color | PIN Number (T568A) | PIN Number (T568B) | Signal Name |
|---|---|---|---|
| Orange/White | 3 | 2 | Transmit + |
| Orange | 6 | 1 | Transmit – |
| Green/White | 1 | 3 | Receive + |
| Blue | 2 | 6 | Not Used |
| Blue/White | 5 | 7 | Not Used |
| Green | 4 | 8 | Receive – |
| Brown/White | 7 | 4 | Not Used |
| Brown | 8 | 5 | Not Used |
In this wiring diagram, you will notice that certain wires are crossed over so that they are not connected to the same pin on both ends of the cable. This is what allows the devices to communicate with each other directly, without the need for a switch or hub.
FAQ
What is the maximum length of an Ethernet crossover cable?
The maximum length for an Ethernet crossover cable is approximately 100 meters (328 feet). However, it is important to note that the longer the cable, the more signal degradation and interference will occur. Therefore, it is recommended to keep the length of the cable as short as possible.
Can an Ethernet crossover cable be used with a switch or hub?
No, an Ethernet crossover cable should not be used with a switch or hub. These devices are designed to work with standard Ethernet cables, and using a crossover cable can cause connectivity issues or damage to the devices.
How do I know if I need an Ethernet crossover cable?
If you are connecting two devices directly to each other, such as two computers or a computer and a printer, you will likely need an Ethernet crossover cable. However, if you are connecting devices through a switch or hub, you will need a standard Ethernet cable.
Can I make my own Ethernet crossover cable?
Yes, you can make your own Ethernet crossover cable using the wiring diagram provided in this article. However, it is important to have the proper tools and knowledge to properly crimp the cable and ensure that the wires are connected correctly. If you are not experienced with working with Ethernet cables, it is recommended to purchase a pre-made crossover cable.
What is the difference between T568A and T568B wiring standards?
The T568A and T568B wiring standards are two different ways in which Ethernet cables can be wired. The primary difference between these standards is the way in which the wires are connected to the pins on the connector. Both standards are commonly used, and the choice between the two typically depends on the preference of the installer or the specific requirements of the device being connected.
