a Patch vs Crossover Cable
When buying cables, there is a possibility that you may choose the wrong cable from patch and crossover cables. As both the patch and crossover cables looks similar, it really becomes difficult to choose the right one. Your perplexity happens when you reach home and you notice that you have not bought the right cable because these two cables cannot be interchanged.
So what are patch cables? Patch cables are straight cables and do not change or swap along its way. The wire ‘one’ on one end comes out as wire ‘one’ on the other end and not as wire ‘two.’ These patch cables are the most widely used Internet cables. These cables are widely used for connecting the computer to the switches, hubs, or routers.
Now let us look at the crossover cables. These cables, as the name suggests, cross over or swap on their way when coming from one end to the other. This means that wire ‘one’ on one end does not come out as wire ‘one’ on the other end. The crossover cables are mainly used for connecting two routers, computers, or hubs. In crossover cables, the wires that come out of the other end match the correct pin at the receiving end.
Worship music for church services. When a crossover cable connects two like devices, like a PC to a PC, or a switch to a switch, the patch cable connects two unlike devices like a PC and a switch.
In computers, crossover cables are used for connecting computers or networks, and a patch cable is used for connecting the computer to the switchboard, router, or hub.
Summary:
The Gigabit Crossover Adapter converts any standard Ethernet patch cable to a crossover cable for 1000 BASE networks and below. Used with a standard Ethernet patch cable, the Gigabit Crossover Adapter can network two computers in a Gigabit network without requiring a hub. This feature is great for creating a personal network in the office, a. Download our CAT 5 Patch/Crossover Cable Creation Guide today! You can usually buy a crimp tool, shown in Figure C, for about $40 from the same place you buy the RJ-45 connectors.

Crossover Cable is used to connect two same type devices back to back to provide a network connection. This can be also called a direct ethernet connection. What makes crossover cable different is the connecting devices are the same type as two computers or two routers etc where the data communication lines should be reversed. The signals should be crossed intentionally where they send signal will be receiving a signal and receive signal will send a signal for the counterpart system.
Crossover Wiring Scheme
There is two pinout schemes named T568A and T568B . A crossover cable uses both of these scheme end of the ethernet cable. You can see these pinout in the following diagram.

We can see the crossover cable connection more clear in the following diagram. The following connections are made to make a crossover cable.
- Connector A Pin 1 <-> Connector B Pin 3
- Connector A Pin 2 <-> Connector B Pin 6
- Connector A Pin 3 <-> Connector B Pin 1
- Connector A Pin 6 <-> Connector B Pin 2
Crossover Cable Usage
Crossover cable is used for different cases where which are depicted with the following diagrams.
- Switch to Switch
- Switch to Hub
- Hub to Hub
- Router to Router
- Router to PC
- PC to PC
Patch (Straight) Cable vs Crossover Cable
Crossover cable is the alternative of the Straight or Patch Cable. They are using the same cables with different pinouts were used for a different type of connections.
- The crossover uses different pinout for the ends like if one end is T-568A another end should be T-568B but in straight cable, both ends will be the same pinout like if one end is T-568A the other end will be T-568A too.
- Crossover cable will be used the same type devices where Straight cable is used for a different type of devices where a crossover of the pins are not required.

Auto MDI is a technology where the cable type can be detected and configured automatically with the software on the network interface card. This is very useful where a crossover cable can be used to connect different types of devices by using Auto MDI technology. Auto MDI is provided by the network interface card. Today most of the network ports like modem, pc, laptop, switch, router use the auto MDI where there is no need to find proper cable type.
