Patch cable to crossover

Crossover cable, as the name suggests, cross over or swap on its way when coming from one end to the other. Unlike patch cable, crossover cable uses two different wiring standards on both end: one end uses the TA wiring standard, and the other end uses the TB wiring standard. Both side connector A and connector B of crossover cable have wire arrangement with different color, and the wires that come out of the connector A should match the correct pin at the connector B.

As shown in the following wiring scheme, you can see that Pin 1 on connector A goes to Pin 3 on connector B, pin 2 to pin 6, pin 3 to pin 1 and pin 6 to pin 2, etc. The crossover cables are mainly used for connecting two routers, computers, or hubs. In brief, a crossover cable connects two devices of the same type to communicate together, like a PC to a PC, or a switch to a switch.

The patch cable connects two different devices to each other, like a PC and a switch. The following scenarios will explain the different applications. If we have two computers connected directly to each other. And both PCs try to transmit on TX wire, their signals will collide. Moreover, nothing will be sent on RX wire.

Connector Guides. Live Chat Need help? These cables are used to connect the same devices. Sometimes we need to share the internet from one pc if the other pc does not have an internet connection.

So to connect pc to pc or from any other similar devices we use crossover cables. Both the ends of the cable consist of different connectors due to the difference in the output serial of the wires in the cable. So taking an example, a rollover cable is connected to TA on one side and TB on the other side. Different serial pinouts can be best understood from the example. Some examples of the crossover cables available in the market are null- modem cable, rollover cable, etc.

Both patch cables and crossover cables are used to connect one device with the other. But the difference is that one can connect similar devices only, whereas the other can connect different devices.
